L04HU AA Safety Instructions, Warnings, and Notes 2. Safety Instructions, Warnings, and Notes 2.1 – Safety Instructions Safety regulations require that during a repair: • Connect the set to the Mains (AC Power) via an isolation transformer (> 800 VA). • Replace safety components, indicated by the symbol h, only by components identical to the original ones. Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard. Safety regulations require that after a repair, the set must be returned in its original condition. Pay in particular attention to the following points: • Route the wire trees correctly and fix them with the mounted cable clamps. • Check the insulation of the Mains (AC Power) lead for external damage. • Check the strain relief of the Mains (AC Power) cord for proper function. • Check the electrical DC resistance between the Mains (AC Power) plug and the secondary side (only for sets which have a Mains (AC Power) isolated power supply): 1. Unplug the Mains (AC Power) cord and connect a wire between the two pins of the Mains (AC Power) plug. 2. Set the Mains (AC Power) switch to the "on" position (keep the Mains (AC Power) cord unplugged!). 3. Measure the resistance value between the pins of the Mains (AC Power) plug and the metal shielding of the tuner or the aerial connection on the set. The reading should be between 4.5 Mohm and 12 Mohm. 4. Switch "off" the set, and remove the wire between the two pins of the Mains (AC Power) plug. • Check the cabinet for defects, to avoid touching of any inner parts by the customer. 2.2 • • • • 2.3 Notes 2.3.1 General • • • Warnings • Complete kit ESD3 (small tablemat, wristband, connection box, extension cable and ground cable) 4822 310 10671. – Wristband tester 4822 344 13999. Together with the deflection unit and any multi-pole unit, flat square picture tubes form an integrated unit. The deflection and the multi-pole units are set optimally at the factory. We do not recommend adjusting this unit during repair. Be careful during measurements in the high voltage section and on the picture tube. Never replace modules or other components while the unit is 'on’. When you align the set, use plastic rather than metal tools. This will prevent any short circuits and the danger of a circuit becoming unstable. In order to prevent damage to ICs and transistors, avoid all high voltage flashovers. In order to prevent damage to the picture tube, use the method shown in Fig. 2-1, to discharge the picture tube. Use a high voltage probe and a multi-meter (position V_dc). Discharge until the meter reading is 0 V (after approx. 30 s). • Measure the voltages and waveforms with regard to the chassis (= tuner) ground (H), or hot ground (I), depending on the tested area of circuitry. The voltages and waveforms shown in the diagrams are indicative. Measure them in the Service Default Mode (see chapter 5) with a colour bar signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated otherwise) and picture carrier at 475.25 MHz for PAL, or 61.25 MHz for NTSC (channel 3). Where necessary, measure the waveforms and voltages with (D) and without (E) aerial signal. Measure the voltages in the power supply section both in normal operation (G) and in standby (F). These values are indicated by means of the appropriate symbols. The semiconductors indicated in the circuit diagram and in the parts lists, are interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors.

Careless handling during repair can reduce life drastically. Make sure that, during repair, you are connected with the same potential as the mass of the set by a wristband with resistance. Keep components and tools also at this potential. Available ESD protection equipment: • • • • All resistor values are in ohms and the value multiplier is often used to indicate the decimal point location (e.g. 2K2 indicates 2.2 kohm). Resistor values with no multiplier may be indicated with either an "E" or an "R" (e.g. 220E or 220R indicates 220 ohm). All capacitor values are given in micro-farads (µ= x10-6), nano-farads (n= x10-9), or pico-farads (p= x10-12). Capacitor values may also use the value multiplier as the decimal point indication (e.g. 2p2 indicates 2.2 pF). An "asterisk" (*) indicates component usage varies. Refer to the diversity tables for the correct values. The correct component values are listed in the Electrical Replacement Parts List. Therefore, always check this list when there is any doubt. Safety Instructions, Warnings, and Notes 2.3.3 Rework on BGA (Ball Grid Array) ICs • General Although (LF)BGA assembly yields are very high, there may still be a requirement for component rework. By rework, we mean the process of removing the component from the PWB and replacing it with a new component. If an (LF)BGA is removed from a PWB, the solder balls of the component are deformed drastically so the removed (LF)BGA has to be discarded. Device Removal As is the case with any component that, it is essential when removing an (LF)BGA, the board, tracks, solder lands, or surrounding components are not damaged. To remove an (LF)BGA, the board must be uniformly heated to a temperature close to the reflow soldering temperature. A uniform temperature reduces the chance of warping the PWB. To do this, we recommend that the board is heated until it is certain that all the joints are molten. Then carefully pull the component off the board with a vacuum nozzle. For the appropriate temperature profiles, see the IC data sheet. Area Preparation When the component has been removed, the vacant IC area must be cleaned before replacing the (LF)BGA. Removing an IC often leaves varying amounts of solder on the mounting lands. This excessive solder can be removed with either a solder sucker or solder wick. The remaining flux can be removed with a brush and cleaning agent. After the board is properly cleaned and inspected, apply flux on the solder lands and on the connection balls of the (LF)BGA. Note: Do not apply solder paste, as this has shown to result in problems during re-soldering. Device Replacement The last step in the repair process is to solder the new component on the board. Ideally, the (LF)BGA should be aligned under a microscope or magnifying glass. If this is not possible, try to align the (LF)BGA with any board markers. To reflow the solder, apply a temperature profile according to the IC data sheet. So as not to damage neighbouring components, it may be necessary to reduce some temperatures and times. More Information For more information on how to handle BGA devices, visit this URL: www.atyourservice.ce.philips.com (needs subscription, not available for all regions) ). After login, select “Magazine”, then go to “Workshop Information”. Here you will find Information on how to deal with BGA-ICs. 2.3.4 Lead Free Solder Some PWBs in this chassis are “lead-free prepared”. This is indicated on the PWB by the PHILIPS lead-free logo (either by a service-printing or by a sticker). It does not mean that leadfree solder is actually used! P b Figure 2-3 Lead-free logo Due to this fact, some rules have to be respected by the workshop during a repair: • Use only lead-free soldering tin Philips SAC305 with order code 0622 149 00106. If lead-free solder paste is required, • • • • 2.3.5 L04HU AA 2. EN 5 please contact the manufacturer of your soldering equipment. Use only adequate solder tools applicable for lead-free soldering tin. Adjust your solder tool so that a temperature around 217 220 deg. C is reached at the solder joint. Do not mix lead-free soldering tin with leaded soldering tin; this will lead to unreliable solder joints! Use only original spare parts listed in this manual. These are lead-free parts! On the website www.atyourservice.ce.philips.com (needs subscription, not available for all regions) you can find more information on: – Aspects of lead-free technology. – BGA (de-)soldering, heating-profiles of BGAs used in Philips sets, and others. Practical Service Precautions • • It makes sense to avoid exposure to electrical shock. While some sources are expected to have a possible dangerous impact, others of quite high potential are of limited current and are sometimes held in less regard. Always respect voltages. While some may not be dangerous in themselves, they can cause unexpected reactions - reactions that are best avoided. Before reaching into a powered TV set, it is best to test the high voltage insulation. It is easy to do, and is a good service precaution. EN 6 3. L04HU AA Directions for Use 3.

ComPair is a further development on the European DST (service remote control), which allows faster and more accurate diagnostics. ComPair has three big advantages: • ComPair helps you to quickly get an understanding on how to repair the chassis in a short time by guiding you systematically through the repair procedures. • ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas. You do not have to know anything about I2C commands yourself because ComPair takes care of this. • ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available. When ComPair is installed together with the SearchMan electronic manual of the defective chassis, schematics and PWBs are only a mouse click away. Snowy picture Check CSM line 6. If this line reads “Not Tuned”, check the following: • Antenna not connected. Connect the antenna. • No antenna signal or bad antenna signal. Connect a proper antenna signal. • The tuner is faulty (in this case line 2, the Error Buffer line, will contain error number 10). Check the tuner and replace/ repair the tuner if necessary. 5.4.2 Specifications Black and white picture If: • The picture improves after you have pressed the AUTO PICTURE button on the remote control transmitter, Then: 1. Press the AUTO PICTURE button on the remote control transmitter repeatedly (if necessary) to choose PERSONAL picture mode. 2. Press the MENU button on the remote control transmitter. This brings up the normal user menu. 3. In the normal user menu, use the MENU UP/DOWN keys to highlight the PICTURE sub menu. 4. Press the MENU LEFT/RIGHT keys to enter the PICTURE sub menu. 5. Use the MENU UP/DOWN keys to select COLOR. 6. Press the MENU RIGHT key to increase the COLOR value. 7. Press the MENU button on the remote control transmitter twice to exit the user menu. ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product. The ComPair interface box is connected to the PC via a serial or RS232 cable. For this chassis, the ComPair interface box and the TV communicate via a bi-directional service cable via the service connector. The ComPair faultfinding program is able to determine the problem of the defective television. ComPair can gather diagnostic information in two ways: • Automatic (by communication with the television): ComPair can automatically read out the contents of the entire error buffer. Diagnosis is done on I2C level. ComPair can access the I2C bus of the television. ComPair can send and receive I2C commands to the micro controller of the television. In this way, it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set. • Manually (by asking questions to you): Automatic diagnosis is only possible if the micro controller of the EN 12 5. Service Modes, Error Codes, and Fault Finding L04HU AA television is working correctly and only to a certain extends. When this is not the case, ComPair will guide you through the faultfinding tree by asking you questions (e.g. Does the screen give a picture? Click on the correct answer: YES / NO) and showing you examples (e.g. Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope). You can answer by clicking on a link (e.g. text or a waveform picture) that will bring you to the next step in the faultfinding process. By a combination of automatic diagnostics and an interactive question / answer procedure, ComPair will enable you to find most problems in a fast and effective way. Note: If you encounter any problems, contact your local support desk. 5.5 The error code buffer contains all errors detected since the last time the buffer was erased. The buffer is written from left to right. When an error occurs that is not yet in the error code buffer, it is displayed at the left side and all other errors shift one position to the right. 5.5.1 Beside fault finding, ComPair provides some additional features like: • Up- or downloading of pre-sets. • Managing of pre-set lists. • Emulation of the Dealer Service Tool (DST). • If both ComPair and SearchMan (Electronic Service Manual) are installed, all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink. Example: Measure the DC-voltage on capacitor C2568 (Schematic/Panel) at the Mono-carrier. – Click on the “Panel” hyperlink to automatically show the PWB with a highlighted capacitor C2568. – Click on the “Schematic” hyperlink to automatically show the position of the highlighted capacitor. 5.4.3 TO I2C SERVICE CONNECTOR PC VCR Power 9V DC I2C E_06532_008.eps 180804 Figure 5-3 ComPair Interface connection 5.4.4 How To Order ComPair order codes: • ComPair Software: ST4191. • ComPair Interface Box: 4822 727 21631. • AC Adapter: T405-ND. • ComPair Quick Start Guide: ST4190. How To Read The Error Buffer You can read the error buffer in 3 ways: • On screen via the SAM (if you have a picture). Examples: – ERROR: 0 0 0 0 0 : No errors detected – ERROR: 6 0 0 0 0 : Error code 6 is the last and only detected error – ERROR: 9 6 0 0 0 : Error code 6 was detected first and error code 9 is the last detected (newest) error • Via the blinking LED procedure (when you have no picture). See “The Blinking LED Procedure”. • Via ComPair. 5.5.2 How To Clear The Error Buffer The error code buffer is cleared in the following cases: • By using the CLEAR command in the SAM menu: – To enter SAM, press the following key sequence on the remote control transmitter: “062596” directly followed by the OSD/STATUS button (do not allow the display to time out between entries while keying the sequence). – Make sure the menu item CLEAR is highlighted. Use the MENU UP/DOWN buttons, if necessary. – Press the MENU RIGHT button to clear the error buffer. The text on the right side of the “CLEAR” line will change from “CLEAR?” to “CLEARED” • If the contents of the error buffer have not changed for 50 hours, the error buffer resets automatically. How To Connect 1. First, install the ComPair Browser software (see the Quick Reference Card for installation instructions). 2. Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with “PC”) of the ComPair interface. 3. Connect the mains adapter to the supply connector (marked with “POWER 9V DC”) of the ComPair interface. 4. Switch the ComPair interface “OFF”. 5. Switch the television set “OFF” with the mains switch. 6. Connect the ComPair interface cable between the connector on the rear side of the ComPair interface (marked with “I2C”) and the ComPair connector at the rear side of the TV. 7. Plug the mains adapter in a mains outlet, and switch the interface “ON”. The green and red LEDs light up together. The red LED extinguishes after approx. 1 second while the green LED remains lit. 8. Start the ComPair program and read the “Introduction” chapter. Error Codes Note: If you exit SAM by disconnecting the AC power from the television set, the error buffer is not reset. 5.5.3 Error Codes In case of non-intermittent faults, write down the errors present in the error buffer and clear the error buffer before you begin the repair. This ensures that old error codes are no longer present. If possible, check the entire contents of the error buffer. In some situations, an error code is only the result of another error and not the actual cause of the problem (for example, a fault in the protection detection circuitry can also lead to a protection).

Example of error buffer: 12 9 6 0 0 After entering SDM, the following occurs: • 1 long blink of 5 seconds to start the sequence, • 12 short blinks followed by a pause of 1.5 seconds, • 9 short blinks followed by a pause of 1.5 seconds, • 6 short blinks followed by a pause of 1.5 seconds, • 1 long blink of 1.5 seconds to finish the sequence, • The sequence starts again at 12 short blinks. Protections If a fault situation is detected, an error code will be generated; and, if necessary, the television set will go into protection mode. Blinking of the red LED at a frequency of 3 Hz indicates the protection mode. In some error cases, the microprocessor does not put the set in protection mode. The error codes of the error buffer and the blinking LED procedure can be read via the Service Default Menu (SDM), or via ComPair. To get a quick diagnosis the chassis has three service modes implemented: • The Customer Service Mode (CSM). • The Service Default Mode (SDM). • The Service Alignment Mode (SAM). DVD Loader - 5.8.1 NVM Editor In some cases, it can be handy if one directly can change the NVM contents. This can be done with the “NVM Editor” in SAM mode. Using this procedure, you can make the contents of the error buffer visible via the front LED. This is especially useful when there is no picture. 5.7 Diagram 0 5.8.2 Power Supply Set Not Working Check Power Supply Mains Switch Bridge Rectifier circuit 6500 Not Ok Check fusible resistor 3510 & circuit before it Ok Check DC voltage at 2505/2507 Not Ok Ok Check fusible resistor 3532 Check 7512 Check IC7511 & IC7531 Ok Set able to start-up No Check other fusible resistor and capacitor in the circuit Yes End E_14480_057.eps 190204 For a detailed mode description, see the relevant sections.

EN 61 8. Alignments 8.1 Index of this chapter: 1. General Alignment Conditions 2. Hardware Alignments 3. Software Alignments and Settings 6. 7. 8. 9. Note: • The Service Default and Alignment Mode (SDAM) is described in chapter 5 “Service Modes, ...”. • Menu navigation is done with the CURSOR UP, DOWN, LEFT, or RIGHT keys of the remote control transmitter. 10. General Alignment Conditions 11. Perform all electrical adjustments under the following conditions: • AC voltage and frequency: 120 V_ac / 60 Hz or 240 V_ac / 50 Hz (region dependent). • Connect the set to the AC power (a.k.a. Mains voltage) via an isolation transformer with a low internal resistance. • Allow the set to warm up for approximately 20 minutes. • Measure the voltages and waveforms in relation to chassis ground (with the exception of the voltages on the primary side of the power supply). Never use the cooling fins / plates as ground. • Test probe: Ri > 10 Mohm; Ci < 2.5 pF. • Use an isolated trimmer / screwdriver to perform the alignments. 12. 13. CONTRAST to “0”. BRIGHTNESS to minimum (OSD just visible). Return to the SAM via the MENU key. Connect the RF output of a pattern generator to the antenna input. Test pattern is a 'black' picture (blank screen on CRT without any OSD info) with a signal strength of 1 V_pp. Set the channel of the oscilloscope to 50 V/div and the time base to 0.2 ms (external triggering on the vertical pulse). Ground the scope at the CRT panel and connect a 10:1 probe to one of the cathodes of the picture tube socket (see diagram B). Measure the cut off pulse during first full line after the frame blanking (see figure “V_cutoff waveform”). You will see two pulses, one being the “cut off” pulse and the other being the “white drive” pulse. Choose the one with the lowest value; this is the “cut off” pulse. Select the cathode with the highest V_dc value for the alignment.

How to change an Option Byte An Option Byte represents a number of different options. Changing these bytes directly makes it possible to set all options very fast. All options are controlled via seven option bytes. Select the option byte (OB1.. OB7) with the MENU UP/ DOWN keys, and enter the new value. Leaving the OPTION submenu and switching the set off with the standby button on the remote saves the changes in the Option Byte settings. Some changes will only take effect after the set has been switched OFF and ON with the AC power switch (cold start). How to calculate the value of an Option Byte Calculate an Option Byte value (OB1 .. OB7) in the following way: 1. Check the status of the single option bits (OP): are they enabled (1) or disabled (0). 2. When an option bit is enabled (1) it represents a certain value (see first column 'value between brackets' in first table below). When an option bit is disabled, its value is 0. 3. The total value of an Option Byte is formed by the sum of its eight option bits. See second table below for the correct Option Bytes per typenumber. Sum Sum Sum Sum Sum Sum Alignments L04HU AA 8.

The chassis has a 'hot' ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis. Introduction The "L04" chassis is a global TV chassis for the model year 2004 and is used for TV sets with large screen sizes (from 21 to 36 inch), in Super Flat and Real Flat executions (both in 4:3 and 16:9 variants). There are three types of CRT namely the 100 degrees, 110 degrees and Wide Screen CRT. • The 100 deg. 4:3 CRT is raster-correction-free and does not need East/West Correction (except when used in AP regions), therefore the corrections needed are Horizontal Shift, Vertical Slope, Vertical Amplitude, Vertical SCorrection, Vertical Shift, and Vertical Zoom for geometry corrections. • The 110 deg. 4:3 CRT comes with East/West Correction. In addition to the parameter mentioned above, it also needs the Horizontal Parallelogram, Horizontal Bow, Horizontal Shift, East/West Width, East/West Parabola, East/West Upper and Lower Corners, and East/West Trapezium correction. • The Wide Screen TV sets have all the correction of the 110 deg. 4:3 CRTs and also have additional picture format like the 4:3 format, 16:9, 14:9, 16:9 zoom, subtitle zoom, and the Super-Wide picture format. In comparison to its predecessor (the M8/L01.1), this chassis is has the following (new) features: • Audio: The sound processor is part of the UOC processor (called “Hercules”). • Video: Enhanced video features, video drivers, and Active Control. • Control: Comparable to M8/L01.1 (e.g. Dual clock, I/O mapping, I/O switching). • Power Supply: Adapted to supply the Hercules IC, and to enable 0.5 W Standby power dissipation. Also provisions are made for future extensions like DVD and iDTV. The standard architecture consists of a Main panel (called "family board"), a Picture Tube panel, a Side I/O panel, and a Top Control panel. The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part. The functions for video/audio processing, microprocessor (P), and CC/Teletext (TXT) decoder are all combined in one IC (TDA1200x, item 7200), the so-called third generation Ultimate One Chip (UOC-III) or “Hercules”. This chip is mounted on the “solder” side of the main panel, and has the following features: Control, small signal, mono/stereo, and extensive Audio/ Video switching in one IC. Upgrade with digital sound & video processing. Alignment free IF, including SECAM-L/L1 and AM. FM sound 4.5/5.5/6.0/6.5, no traps/bandpass filters. Full multi-standard color decoder. One Xtal reference for all functions (microprocessor, RCP, TXT/CC, RDS, color decoder, and stereo sound processor). 9.2 Power Supply 9.2.1 Block Diagram Vbatt (to deflection & DVD interface board) -Vaudio SWITCH FILTER & MH COIL RECTIFIER MAIN SMPS +Vaudio +6V (from AUX SMPS for Stdby feedback) Degaussing Supply (V_DG) Derived from =Vaudio Stdby_Con (from HERCULES) RELAY Power_Down (to HERCULES) DEGAUSS +3V (to derive HERCULES supply 1.8V) AUX SMPS +6V (to derive HERCULES & TUNER) supply +5V & +3.3V) Vaux (for IDTV) B (connected to HERCULES port B to switch ON/OFF Vaux) E_14480_072.eps 120504 Figure 9-1 Block diagram power supply Stdby_con signal The Hercules generates this signal.

L04HU AA Circuit Descriptions, List of Abbreviations, and IC Data Sheets Table 9-3 PSU voltage overview Startup Sequence When the set is connected to the AC power, the rectified line voltage (via winding 4-5 of L5531 connected to pin 14 of IC7531) will start the internal voltage source to charge the V_cc capacitor (C2532). The IC starts to switch as soon as the V_cc reaches the V_cc start level of 9.5 V. This supply is automatically taken over by winding 1-2, as soon as the V_cc is high enough, and the internal supply source will stop (for high efficiency switching).

An internal current charges the V_cc capacitor (2532), and the start-up sequence is initiated when this voltage reaches a level of 9.5 V. Note: The output power is disabled when the voltage gets below 9 V (UVLO). Operating range is between 0 to 40 V. 5 RC Frequency setting 6 REG This pin is connected to the feedback loop. The pin contains two functions: 1) Between 1 to 1.425 V it controls the "on" time. 2) Above the threshold of 3.5 V, it is possible to initiate "burst mode" standby. 11 Demag Before the Hercules (IC7200) can generate horizontal drive pulses, the +3.3V supply voltages must be present. After the start up command of the microprocessor (via I2C), the Hercules outputs the horizontal pulses. These horizontal pulses begin “initially” with double line frequency and then change “gradually” to line frequency in order to limit the current in the line stage (slow-start). The VDRA and VDRB signals are the balanced output currents (sawtooth shaped) of the frame oscillator (pins 106 and 107 of the Hercules). These output signals are balanced, so they are less sensitive to disturbances. This pin is connected to the V_cc winding of 5531. It has three functions: 1) During Magnetisation, the input voltage is sensed to compensate OCP level for OPP. 2) During demagnetisation, the output voltage is sensed for OVP and 3) A comparator is used to prevent continuous conduction when output is overloaded. 12 Sense This pin contains three different functions.: 1) Dectection of soft start, protection levels of 2) OCP, and 3) SWP. 14 Drain This pin is connected to the drain of the switch or center tap of the transformer. It contains three functions: 1) M-level (mainsdependent operation-enabling level), 2) Supply for start-up current, and 3) Valley detection. There is a current source inside the UOC at pin 102. This pumps energy in the capacitor connected to this pin producing a pure saw tooth. The vertical drive signals and the E/W correction signal are derived. Pin 108 is the East-West drive (or AVL), and it is a single ended current output. The correction for “horizontal width for changed EHT” from this pin is available by setting the HCO bit to “1”. As C2532 of IC7531 is charged, it will also start to charge the V_cc capacitor (C2511) of IC7511. Via resistor R3519 and C2511, the TEA1506 starts to switch as soon as the V_cc voltage reaches the V_cc start level of is about 11 V. The V_cc voltage is automatically taken over by the main transformer L5512 (winding 2-3) when the V_cc is high enough (when this voltage is even higher than the voltage on C2511, there is no current flow from C2532 to C2511 due to diode D6512). The Phase-2 Compensation available at pin 113 gives frame correction for high beam currents. The phase compensation signal is used to correct the phase of the picture from the horizontal drive signal. Pin 63 is the SANDCASTLE output (contains all sync info) and also HORIZONTAL FLYBACK (HFB) input. Pin 97 is the EHT tracking/over-voltage protection pin. The HCO bit can switch on the tracking on EW. If the voltage at pin 97 exceeds 3.9 V, the over-voltage protection will be activated and the horizontal drive is switched “off” via a slow stop. Table 9-2 Pinning overview TEA1506 9.2.4 Pin Symbol Description 2 This pin is connected to the supply voltage. When this voltage is high (Vcc_start level, about 11 V), the IC will start switching. When the voltage is lower than Vcc_uvlo (about 8.7 V), the IC will stop switching.Note: This pin is not self supplied by internal source like in TEA1507 Vcc 3 Gnd This pin is Ground of the IC. 6 Ctrl This pin is connected to the feedback loop. The pin will control the "on" time between 1 V to 1.5 V. 7 Demag This pin is connected to the Vcc winding of 5512. It contains three functions: 1) During magnetisation, the input voltage is sensed to compensate OCP level for OPP, 2) During demagnetisation, the output voltage is sensed for OVP and 3) a comparator is used to prevent continuous conduction when the output is overloaded. 9 Sense This pin contains three different functions: 1) dectection of soft start, protection levels of 2) OCP, and 3) SWP. 11 Driver This pin will drive the (MOSFET) switch. 12 HVS This is High Volt Spacer (n.a.) 14 Drain Connected to the Drain of the external MOSFET switch, this is the input for valley sensing and initial internal supply. 9.3.2 Horizontal Deflection There are several executions (depending on the CRT): • Sets with no East-West correction. The principle of the horizontal deflection is based on the quasi-diode modulation circuit. This horizontal deflection circuit supplies the deflection current and auxiliary voltages from the LOT. • Sets with East-West correction. The principle of the horizontal deflection is based on a diode modulator with east-west correction. This horizontal deflection circuit supplies the deflection current and auxiliary voltages from the LOT. • Sets with dynamic East-West correction. The principle of the horizontal deflection is based on a diode modulator with dynamic east-west correction for picture tubes with inner pincushion. This horizontal deflection circuit supplies the deflection current and auxiliary voltages from the LOT. Standby Mode In this mode, IC7511 (TEA1506) will be totally disabled. So there is no voltage on the main transformer output. But IC7531 (TEA1523) will still work and will provide the necessary output voltages (6V -> 5V, 3.3V, 3V -> 1.8V) to the Hercules (IC7200). Basic Principle During a scan period, either the Line Transistor or diode(s) conduct to ensure a constant voltage over the deflection coil (that results in a linear current). During the flyback period, the Line Transistor stops conducting, and the flyback capacitor(s) together with the inductance of the deflection coil creates oscillation. Circuit Descriptions, List of Abbreviations, and IC Data Sheets L04HU AA 9. EN 69 First Part of Scan Pin 62 of the UOC delivers the horizontal drive signal for the Line Output stage. This signal is a square pulse of line frequency. L5402 is the flyback drive transformer. This transformer de-couples the line output stage from the UOC. It has a direct polarization. The flyback drive circuit works with the start-up supply taken from +6V of the Aux supply (and subsequently taking from VlotAux+9V). When the H-drive is high, TS7404 conducts, and transformer L5402 starts to store energy. The base of the line transistor TS7405 is low and therefore blocks. The current in the deflection coil returns from diode D6404. frequency) taken from the line aux output. Then a series of width-modulated pulses is formed via two inverted phase amplifiers, filtered by an inductor, which then directly drive the diode modulated line circuit. Second Part of Scan When the H-drive is low, TS7404 does not conduct, and the energy that is stored in the transformer will transfer to the secondary, making the base of the Line Transistor high. Then the Line Transistor starts to conduct. The current in the deflection coil returns from the transistor in another direction. Upon entering the picture geometry menu in the SAM mode, the following corrections will be displayed. • EWW: East West Width. • EWP: East West Parabola. • UCP: Upper Corner Parabola. • LCP: Lower Corner Parabola. • EWT: East West Trapezium. The East-West drive circuit realizes them all. The settings can be changed by a remote control. All changed data will be stored into the NVM after the geometry alignment. East-West Correction To achieve a good geometry, dynamic S-correction is needed. The design is such that the tube/yoke needs East-West correction. Besides that, an inner pincushion is present after East-West correction. The line deflection is modulated with a parabolic voltage (frame frequency). In this way it is not so much at top and bottom, and much more in the middle. Flyback At the moment the H-drive becomes high, the base of the Line Transistor becomes low. Both the Line Transistor and the Flyback Diode will block. There is an oscillation between the flyback capacitor C2412 and the deflection coil. Because of the inductance of the LOT, the Line Transistor cannot stop conducting immediately. After the Line Transistor is out of conduction, the flyback pulse is created. The flyback capacitor charges until the current in the deflection coil reduce to zero. Then it discharges through the deflection coil and the deflection current increases from the other direction. The flyback diode conducts and is back to the first part of the scan. Panorama For Wide Screen sets, the S-correction of the picture has to adapt between the different picture modes. In particular, between 16:9 Wide Screen and 4:3 picture modes. This is achieved with the (separate) Panorama circuit (see diagram “G”). A signal (I2SDI1) from the UOC controls the state of TS7463. When in the normal 16:9 Wide Screen mode, the signal is “low” and therefore TS7463 is switched “off”. When the 4:3 mode is selected, this signal from the UOC is pulled “high”, switching TS7463 “on”. The relay 1463 on the Panorama panel is subsequently turned “on” and, in effect, paralleling capacitor C2475/C2474 to the S-Cap C2469/ C2470. This changes the overall effective S-correction. The relay is switched “on” in 4:3 and Superwide picture modes. Linearity Correction Because the deflection coil has a certain resistance, a picture without any linearity issues cannot be expected. L5401 is the linearity coil to compensate for this resistance. It is a coil with a pre-magnetized core. This correction is called linearity correction. 9.3.3 Horizontal S-Correction Because the electronic beam needs to travel a longer distance to both sides of the screen than the center, the middle of the screen would become narrower than both sides. To prevent this, a parabolic voltage is applied across the deflection coil during scan. To create this parabolic voltage, a capacitor called S-cap (C2417/C2418) is used as a voltage source during scan. The sawtooth current of the deflection through this capacitor creates the required parabolic voltage. This correction is called S-Correction. The horizontal deflection provides various auxiliary voltages derived either directly or indirectly from the secondary pins of the LOT: • +9V: This supplies the Hercules’s flyback driver. • +11V: This supplies the frame amplifier. • -12V: This supplies the frame amplifier. • 50V: This supplies the frame amplifier. • Filament: This supplies the heater pins of the picture tube. • VideoSupply (+200V from primary side of LOT): This supplies the RGB amplifier and Scavem circuit at the CRT panel. Mannheim-Circuit When the EHT is heavily loaded with a bright line, the flyback time can be increased a bit in this situation. As a result, the scan delays a bit causing a DC-shift to the right in the next line, which would create a small spike on the S-cap. This spike oscillates with the inductance of the deflection coil and the primary of LOT. The result is visible in vertical lines under horizontal white line. This is called the Mannheim-effect. To prevent this from happening, a circuit called Mannheimcircuit is added. This consists of C2415, R3404, R3417 and D6406. During the scan, C2415 is charged via R3417. During the flyback, the S-correction parabola across the S-Cap C2417/C2418 is in its most negative, and D6406 conducts. Thus, C2415 is switched in parallel to C2417/C2418 during flyback. As C2415 is much larger than C2417/C2418, the voltage across C2415 reduces the Mannheim-effect oscillation. Class D East-West Driver To reduce the power loss of the normal used linear East-West amplifier, a class-D East-West circuit is used. To achieve this, the East-West parabola waveform EW_DRIVE from the Hercules (frame frequency) is sampled with a saw tooth (line Auxiliary Voltages Notes: • The V_T voltage (to tuner) is drawn from V_batt. • The EHT voltage is generated by the Line Output Transformer (LOT). The Focus and Vg2 voltages are created with two potentiometers integrated in the transformer. 9.3.4 Beam Current The beam current is adjusted with R3451 and R3452. The components R3473, R3453 and C2451 determine the EHT_info characteristic. The voltage across C2412 varies when the beam current changes. This EHT_info is used to compensate the picture geometry via pin 97 of the Hercules when the picture changes rapidly, and compensate the phase 2 loop via pin 113 of the Hercules. Also from the EHT_info line, a BCL signal is derived and sent to the Hercules for controlling the picture’s contrast and brightness. When the picture content becomes brighter, it will introduce: EN 70 9. L04HU AA Circuit Descriptions, List of Abbreviations, and IC Data Sheets • Geometry distortion due to the impedance of the LOT causing the EHT to drop. • Picture blooming due to the picture characteristics Because of the above mentioned, we will need a circuit for Beam Current Limiter (BCL) and EHT compensation (EHT_info). These two circuits derive the signal from the picture tube current info through LOT pin 10. across R3482 will tend to increase as well, while the voltage across D6481 is fixed. Up to certain level (triggering point), TS7481 will be “on” and will force the EHT_info > 3.9 V. The chassis will be shut down through a soft stop sequence. 9.3.7 The Frame stage consists fully of discrete components. This has the advantage for better flash behavior than when an IC was used. BCL • When the BCL pin voltage goes to 2.8 V, the Hercules will start to limit CONTRAST gain. • When it reaches 1.7 V, then the BRIGHTNESS gain limit will start to react. • When BCL pin voltage goes to 0.8 V, the RGB will be blanked. The Frame differential drive signal from the Hercules comes from a current source. Resistors R3460 and R3461 convert them into a voltage, and feed them into the differential amplifier TS7455 and TS7456. The output of TS7456 is input to the next amplification stage of TS7452. Finally, TS7451 and TS7453 deliver the Vertical yoke current to the coil and feedback through the sensing resistors R3471 and R3472. D6458 and TS7454 are used to bias TS7451 and TS7453, to get rid of zero crossovers, which can cause horizontal lines at the screen center. The negative supply is from -12V and the positive scanning supply is from +12V through D6459. The flyback supply is derived from D6455, D6456 and C2456. This circuit is a voltage doubler, which stores energy in C2456 during the Line flyback period and delivers the energy to C2465 during the Line scanning period. Throughout the Frame period, the charging and discharging of C2456 works alternatively. However, at the first half of the Frame scanning, TS7451 is “on” and consumes all the charge from C2456. When entering 2nd half Frame period, TS7451 is “off”, so C2456 will gradually charge up to the required flyback supply. Components TS7483, R3490, R3491, R3492, and C2483 are for fast beam current limiting (e.g. with a Black-to-White pattern). Components R3454, D6451, D6450, C2453, R3493, and C2230 are for average beam current limiting. C2453 and R3493 also control the timing where average beam current limiting is more active or less active. EHT_info The “PHI2 correction” is to correct the storage time deviation of the Line Output Transistor, which is causing geometry distortion due to brightness change. Line EHT_info is to correct the geometry distortion due to EHT deviation. Both of them feedback through the EHTO and PH2LF pin, and correct the geometry through the East-West circuit. Power Down The power down connection is for EHT discharge during AC Power “Off” state. In the Hercules, if EHT_info > 3.9 V, it will trigger the X-ray protection circuit via a 2fH soft stop sequence. The Hercules bits OSO (Switch Off in Vertical Over scan) and FBC (Fixed Beam Current Switch Off) will discharge the EHT with 1mA cathode current at over-scan position. During switch-off, the H_out frequency is doubled immediately and the duty cycle is set to 25% fixed, during 43 ms. The RGB outputs are driven “high” to get a controlled discharge of the picture tube with 1 mA during 38 ms. This will decrease the EHT to about half the nominal value (= safety requirement). When bit OSO is set, the white spot/flash during switch-off will be written in overscan and thus will not be visible on the screen. Careful application must guarantee that the vertical deflection stays operational until the end of the discharge period. 9.3.5 9.3.6 C2463, R3464 and D6457 are for boosting the base voltage of TS7451 during the flyback period and the 1st half Frame period as well. C2463 is charged by D6457 during the 2nd half scanning. R3467 and R3468 are for oscillation damping. The V_guard protection is to protect the Frame stage if a fault condition happens. The V_guard will sense the pulse with voltage > 3.8 V and period < 900 us. Any signal out of this range will be considered as fault, and the chassis will be shut down. 9.3.8 X-ray Protection The X-ray protection circuit rectifies the filament voltage and uses it to trigger TS7481 when the EHT is too high. TS7481 is biased at “off” condition by D6480, R3482, and R3483 during normal operation. When the EHT goes too high, the voltage Tilt and Rotation The rotation control signal is a PWM output from the UOC. It is filtered by R3252, R3246, R3259 and C2259. The DC voltage after filtering at C2259 will be amplified by R3245 (Main Board) and R3390 (CRT panel). The output stage functions similarly as in M8/L01.1 with rotation IC TDA8941P. TS7331/TS7382 and TS7332/TS7381 will function alternatively corresponding to the rotation setting. DAF The Dynamic Astigmatic Focus (DAF) circuit is required by 34RF sets only. It provides vertical DAF and horizontal DAF. Both of the parabola signals are derived through integration by using chassis available signals: • The vertical parabola is using RC integration (via R3403 and C2401) on the Frame sensing resistor saw tooth (Frame_FB). • The horizontal parabola is obtained by 2 RC integration (R3409, R3410, C2402, C2403) on the +9V LOT output. Both of the parabolas are added on the output stage through adder TS7402 and TS7403. The collector of TS7402 emitterdrives TS7401 and is amplified by pull up resistor R3411. D6401 and C2405 provide the rectified supply voltage. Vertical Deflection 9.3.9 CRT panel The RGB amplifier stage is exactly the same as in M8/L01.1. However, the RGB amplifier IC has been changed to TDA6107AJF or TDA6108AJF. The “A” indication is with gain of “80” rather than “50” in M8/L01.1. The diode D6332 used in the former chassis, to solve the bright screen during start up, is not required because this IC has the error correction implemented. Scavem In certain versions, the Scavem feature is used to enhance the sharpness of the picture. The RGB signals are first differentiated and subsequently amplified before feeding to an auxiliary coil known as the SVM coil. The current, flowing through the SVM coil during the picture intensity transients, modulates the deflection field and thus the scan velocity. Circuit Descriptions, List of Abbreviations, and IC Data Sheets During the first half of the intensity increase, the scan velocity is increased (thus decreasing the current density by spreading it on a wider area). During the second half of the intensity increase, the scan velocity is decreased (increasing the current density by concentrating it on a smaller area). The increasing current density transition is sharpened. A decreasing current density transition is processed in a similar way and is also sharpened. In this chassis the SCAVEM signal is different from its predecessor because the Hercules generates the differential SCAVEM signal inside the IC. The supply of the SCAVEM is taken from V_bat through a 1k5 / 5 W resistor. Compared with the M8/L01.1, this has the advantage of getting better performance for the pattern with tremendous SCAVEM current (like V_sweep). In this former chassis, because the supply was taken from the 200 V through a 8k2 / 5 W resistor, the supply dropped significantly during a large SCAVEM current. In this chassis, the drop due to the pattern will be less because of the lower supply voltage impedance. In the Main Board, 1st stage amplification is taken care by 7208 with the pull up resistors (3361, 3387) located in the CRT panel. TS7361 and TS7362 is the current buffer delivering the current to the output stage. The diode D6361 is to lightly bias these transistors, to get rid of the zero crossover of the stage. After that, the signal is ac-coupled to TS7363 and TS7364 where the emitter resistors (R3364 and R3370) will determine the final SCAVEM current. TS7363 and TS7364 are biased by R3363, R3366, R3367 and R3368. C2387, R3388, R3389, R3365, R3369, C2384, and C2385 are used for suppressing unwanted oscillations. The function of TS7376 is to limit the SCAVEM current from going too high. It basically senses the voltage after R3373 and clamps the SCAVEM signal through D6367 and C2376. 9.4 Control The Micro Controller is integrated with the Video Processor, and is called the Hercules. For dynamic data storage, such as SMART PICTURE and SMART SOUND settings, an external NVM IC is being used. Another feature includes an optional Teletext/Closed Caption decoder with the possibility of different page storage depending on the Hercules type number. The Micro Controller ranges in ROM from 128 kB with no TXTdecoder to 128 kB with a 10 page Teletext or with Closed Caption. 9.4.1 Block Diagram The block diagram of the Micro Controller application is shown below. # !$$% KEYBOARD/ PROTECTION CIRCUIT STBY_CON VOLUME/MUTE/TREBBLE /BASS/PANORAMA KEYBOARD/PROTECTION INPUT WRITE PROTECT POWER GOOD OUTPUT LIGHT SENSOR LED IR " !

The IF output from the Tuner is fed directly to either the Video-IF or the Sound-IF input depending on the type of concept chosen. There are mainly two types of decoder in the Hercules, an analog decoder that decodes only Mono, regardless of any standards, and a digital decoder (or DEMDEC) that can decode both Mono as well as Stereo, again regardless of any standards. In this chassis, the analog decoder is used in two cases: • It is used for AM Sound demodulation in the Europe SECAM LL’ transmission. • It is used for all FM demodulation in AP AV-Stereo sets. 9.8.1 Diversity The diversity for the Audio decoding can be broken up into two main concepts: • The Quasi Split Sound concept used in Europe and some AP sets. • The Inter Carrier concept, used in NAFTA and LATAM. The UOC-III family makes no difference anymore between QSS- and Intercarrier IF, nearly all types are softwareswitchable between the two SAW-filter constructions. Simple data settings are required for the set to determine whether it is using the Inter Carrier or the QSS concept. These settings are done via the “QSS” and “FMI” bit found in SAM mode. Due to the diversity involved, the data for the 2 bits are being placed in the NVM location and it is required to write once during startup. On top of that, it can be further broken down into various systems depending on the region. The systems or region chosen, will in turn affect the type of sound standard that is/are allowed to be decoded. • For the case of Europe, the standard consists of BG/DK/I/ LL’ for a Multi-System set. There are also versions of Eastern Europe and Western Europe set and the standard for decoding will be BG/DK and I/DK respectively. FM Radio is a feature diversity for the Europe sets. The same version can have either FM Radio or not, independent of 9. EN 75 the system (e.g. sets with BG/DK/I/LL’ can have or not have FM radio). For the case of NAFTA and LATAM, there is only one transmission standard, which is the M standard. The diversity then will be based on whether it has a dBx noise reduction or a Non-dBx (no dBx noise reduction). For the case of AP, the standard consists of BG/DK/I/M for a Multi-System set. The diversity here will then depends on the region. AP China can have a Multi-System and I/DK version. For India, it might only be BG standard.
