2. SAFETY WARNINGS
Panels used in LCD and LED panel televisions are quite sensitive in electrical and
physical aspects. Therefore, the following warnings should be observed.
1. Panel surface is quite sensitive and can be damaged easily. Take care to avoid
scratches on the panel surface. When you need to lay down the panel, place it on a
floor, which will not cause damages. Besides, do not use rough materials when
touching or wiping the panel clean.
2. Keep panel surface clean. Put on rubber gloves when touching panel surface. To
clean the surface, use a mild cleaning agent that does not get electrified.
3. Keep LCD and LED module away from water. Spilling water in or on the panel
causes electrical damage. It should be wiped dry, if needed.
4. Avoid sudden temperature and humidity changes.
temperature and humidity may harm the panel.
Sudden changes of
5. High temperature and humidity shortens product life. LCD and LED panels are not
suitable for use under high temperature and humidity conditions. The user should
observe the stated values of temperature and humidity.
6. Keep it away from harmful (corrosive) gases. Corrosive gases damage chemical
and electronic structure of LCD and LED panel.
7. Static electricity flow may damage the panel. LCD and LED module contain
materials sensitive to static electricity such as CMOS and etc. The body should be
grounded before touching the panel. Also, you must not touch connector areas with
bare hands.
8. The same image should not stay on the screen for prolonged times. Keeping the
same image on the screen for a long time may lead image retention and the panel
may get damaged. Therefore, TV should be turned off when not in use and the image
should be changed within certain intervals when displaying still images.

3.2.Functional Features
TF-chassis products are intended to drive all screen sizes between 19" and 46" over
a single chassis unlike SU and T5-chassis products. The project will support LCD and
LED panels. In small screens (19”, 22”), DVD Combo feature will be provided and
DVB-T2 features will be included in the product range. Hotel TV with Timer (with
Swan and Klein cabinet) aims to provide Hotel TVs with the feature of cloning via
USB; and USB PVR feature will be supported for all screen sizes. Besides, MPEG4
low cost products with 1 HDMI will be offered with this chassis (26”-32” LCD).
Our televisions with TF chassis support both analog and digital broadcasts. As is
known, digital broadcasts are divided in three as terrestrial digital broadcasting (DVBT/DVB-T2: Digital video Broadcasting Terrestrial), cable digital broadcasting (DVB-C:
Digital video broadcasting cable) and digital satellite broadcasting (DVB-S: Digital
video broadcasting satellite). Our TF-chassis televisions support DVB-T/C and DVBT2 (optional) broadcasting. Digital receiver unit of the product processes signals
coming from digital transmitters and convert them into audio and video of superior
quality. It enables you to access video, music and photo file and play those media.
In our country, DVB-T (Digital Terrestrial Broadcasting) has been tested by TRT in
three metropolitan cities, but private broadcasting companies have not started DVB-T
broadcasting yet. DVB-C (Digital Cable Broadcasting) has been started over the
cable TV network called Teledünya. In DVB-T broadcasting, MPEG2 and MPEG4
standards are currently supported. MPEG defines compression algorithms used in
digital terrestrial broadcasting. Our TF-chassis products support MPEG2 and MPEG4
broadcasting. In today's digital broadcasting, emergence of high definition digital
broadcasts (HD) has brought the use of MPEG4 standard, which is more productive.
Supporting all systems of analog broadcasting (multisystem), TF chassis has image
improvement algorithms such as 3D comb filter, 3D deinterlacer, DLTI and DCTI
features. DNR (digital noise reduction) and MPEGNR (MPEG noise reduction)
improvements are used. Moreover, it features sound improvement algorithm SRS TS
HD; supports AC3 (Dolby digital), AC3+ (Dolby digital plus), AAC and HE-AAC coded
audio broadcasts in digital broadcasting.
To summarize, TF-chassis products support the following features.
• HDMI-CEC
• DVB-T/T2/C
• USB-PVR
• DVD-COMBO
• CI+
• Full HD (100Hz)
• HD-Ready

3.3.Special Features
3.3.1. Next-Generation Digital Terrestrial Broadcasting (DVB-T2)
DVB-T stands for Digital Video Broadcasting-Terrestrial. The frequencies used for
DVB-T are UHF and VHF channels that we are familiar from analog broadcasting.
Thanks to digital broadcasting, those channels are used more productively compared
to analog technique. A single frequency contains many television channels. COFDM
modulation divides the band width among thousands of individual carriers. Each
carrier is encoded with defined QPSK, 16-QAM or 64-QAM modulation technique.
Data rate per channel is approximately 12 and 20 Mbit/s depending on the set
parameters. Data rate of a
frequency can be divided to
maximum four programs.
Each divided program has
averagely 3 and 5 Mbit/s rate.
(COFDM)
Operating
much
more
productively than currently used DVB-T technology, DVB-T2 offers the most
appropriate environment for HD broadcasts by using MPEG4 compression
technique. Started to be used in the UK, DVB-T2 technology will also be put into
practice by Finland and Serbia soon. Besides, DVB-T2 is expected to be deployed in
many European countries, primarily Italy and Spain.

7. GENERAL OPERATING PRINCIPLES OF TV
24
February 11
TF CHASSIS / TELEVISION
7.1.Chassis General Operating Principle
As it is also seen in block diagram, system structure is quite simple and clear. This is
owing to the fact that digital and analog controls can be performed with a single
integrated circuit used in TF chassis. Besides, modulator and demodulator are
located in the main IC. In short, all sources provide input to the main integrated
circuit; after the video has been processed, it is sent to the panel from the integrated
circuit via LVDS lines. Likewise, the sound is sent to the sound amplifier after being
processed. DDR is used for main IC and MEMC circuit's processes.
While performing these processes, the main integrated circuit reads software installed
on flash and EEPROM data installed on EEPROMs. RAMs are used for the
processes performed within the integrated circuit.
25
February 11
TF CHASSIS / TELEVISION
Surely, the system should be supplied power in 5V, 3.3V, 1.8V, 1.05V, 2.5V and 1.2V,
which is required for these processes.
7.2.DC Power Stage
Chassis and supply unit are connected via S606 connector. In TF-chassis products
with large size (26”-46”), only 5V is fed from the supply unit (PSU) when the product
is in Stand-By. 12V and 24V supplies are switched on by the control of main
integrated circuit when television is going out of Stand-By.
26
February 11
TF CHASSIS / TELEVISION
In TF-chassis products with smaller size, 12V and 5V will be supplied from supply unit
(LIPS) in Stand By mode.
On this connector (S606), 3 main control signals are sent to the power supply as well.
The first signal is “POWER_SW”; it is sent to the power source from 8th pin. It
switches on 12V and 24V voltages in the "ON" status. The second signal is
“BL_CTRL”; it switches panel's backlights on or off. This signal is sent from 5th pin to
the power supply. In cases where 5th leg is high (3.3V), backlights are switched on.
The third signal is “BRI_ADJ”; it determines the illumination level of backlights
depending on the value set in the user menu. It can be a square wave or a DC value
according to the panels using PWM dimming and DC dimming.
In Stand-By mode, only VCC3.3V-ST output and IC600 integrated circuit are on
among the regulators on the chassis. Integrated circuits and regulators are kept off in
Stand-By mode as long as possible to ensure lower power consumption. In TF
chassis, Stand-By power consumption is 0.5W.
After power supply is turned on with “POWER_SW” signal, IC601 generates 1.05V
and thus, when POWER GOOD (PG) signal steps in, 1.8V and 2.5V are generated by
IC606 and IC605, respectively. VCC3.3V signal is switched with IC603 and VCC5V
signal is switched with IC604 (turns on).
In our smaller size (19”-22”) products with TF-chassis, Panel T-CON supply voltage
(12V) is directly switched as VCC PANEL signal by T607 Mosfet over S606 DC power
connector, and then sent to the panel as PANEL VCC.
In the large size products, Panel T-CON supply voltage is generated by means of
L608.
In 100Hz products, Panel T-CON supply voltage is generated by means of L609.

8.OPERATING PRINCIPLES OF CIRCUIT COMPONENTS
8.1.Circuit components on the chassis
IC402, MSD3819TX Main Integrated Circuit:
IC402, which is our main IC, has the following features: Digital (DVB-T/T2/C) and
analog broadcasting demodulator, USB recording feature, Broadcast and A/V
decoder (NTSC/PAL/SECAM, DVB, Full HDTV, DVD, MPEG-2 and MPEG-4), 32-Bit
Linux based processor, Audio processor and interface, 2 USB, 4 HDMI, 2 DDR ram
input
This integrated circuit collects and processes data coming from all inputs and sends
audio and video output to the speaker over amplifier and to the panel over LVDS line.
This integrated circuit has more than 500 legs. Special equipment is required for
installation and removal. Therefore, these integrated circuits are designed with very
low error ratios. If you suspect an error with main IC on TV, firstly supplies of this IC
should be checked. There are 4 input supplies as 3.3V, 2.5V, 1.8V and 1.05V.
Extremely low or high ratings of these supplies might cause image freezing, some
sources' not functioning or losing the picture completely. Besides, the problem might
be originated in software, EEPROM, flash, crystal or RAM. If there is a problem, we
cannot be sure that it is originated in IC before checking it out.
28
February 11
TF CHASSIS / TELEVISION
While turning the TV on, main IC switches the system on by reading the flash and
turns the power supply on by switching the “POWER SW” signal to high. Then, panel
signals “BRI_DJ (Sets backlight brightness), “TCON_ON” (turns on Panel TCON
board, panel supply) and “BL_CTRL” (turns on the backlight) switches on the panel
backlights and the image appears on TV.
IC200, IC201, W9751G6JB-25, DDR Ram:
29
February 11
TF CHASSIS / TELEVISION
RAM is the place where main integrated circuit performs the processes such as
decoding, encoding, image and video resolution in all applications. Similar to a
calculator, it constantly carries out the processes to ensure the operation of TV. RAM
supplies should be carefully checked. Fluctuations in RAM supplies may cause
errors. Sudden rise or fall of RAM supply might freeze the television and cause
picture lagging.
IC101, TC58NVG0S3EBAI4LR0, NAND Flash Memory:
Flash memory is where the system operating software is installed. It can be inserted
into IC101 and IC102 positions on the circuit. However, only 1GBit flash is being used
on IC101 position.
System software starts to operate as soon as TV is turned on. All TV functions are
controlled by software installed in this flash.
If any problem occurs in the flash memory, the chassis will not function as the
software in the chassis is not functioning. As soon as the chassis is energized, LED
located on the front panel will start flashing. This means that main integrated circuit
has read and started to operate the software. IF LED is constantly illuminated but not
flashing, and the chassis is not turned on even though the chassis is energized, this
means either software was not read due to a problem in flash memory or it could not
be started due to a problem in main integrated circuit.
IC501,TAS5707PHPR, Audio Amplifier:
30
February 11
TF CHASSIS / TELEVISION
The integrated circuit of audio amplifier amplifies audio data coming from main IC to
the desired level and sends it out. There is not any dedicated IC502 amplifier for
headphone socket. After the output has been filtered on main IC, it is sent to
headphone socket through IC502 (MAX9728AETC+).
IC1002, MSB1231, DVBT2 Demodulator
DVBT2 demodulator enables the reception and modulation of next generation digital
terrestrial broadcasting (DVBT2), and the creation of audio and video. For DVBT2
modulated broadcasts to be received by TF-chassis product, DVBT2 should be
selected ON from service menu in addition to lineup of DVBT2 modulator and
peripheral components on the chassis.
31
February 11
TF CHASSIS / TELEVISION
TU300, TDAG8-D11A, Tuner:
TF chassis utilizes hybrid tuner. Receiving both analog and digital broadcasts from the
cable, the tuner obtains analog and digital IF (inter frequency signals) of the
broadcasts. This ALPS brand tuner uses 5V power as antenna feed for active
antennas. This selection can be made from user menu and controlled by 5V_TA
signal from the chassis (Leg 1). When the signal of analog broadcast is low
depending on the RFAGC signal coming from main IC, signal levels are strengthened
by the coefficient of amplification that is calculated by main IC (Leg 2). Tuner is
locked to the desired channel by communicating with main board and main IC,
depending on the selected source, through I2CT2_SCL and I2CT2_SDA lines. It
filters other frequencies and selects the desired frequency and transforms the signal
as to enter main IC. This chassis does not have a separate demodulator IC.
Demodulation is performed in main IC. Here, I2C protocol is used for the purpose of
communication (Leg 7 and 8). Leg 6 sends 4MHz signal of 33V as reference. We
leave this leg empty. Tuner's own power supply is 5V (Leg 3).
32
February 11
TF CHASSIS / TELEVISION
Leg 9 gives analog IF output while Leg 11 and Leg 12 give digital IF output. Leg 10
sends IF AGC value used in digital broadcasting, from the digital demodulator.
IC103, M24C32, Panel EEPROM:
Panel EEPROM contains resolution info of the panel that is obtained after panel
adaptation as well as the white settings of the panel. Panel EEPROM file is named as
“Panel.bin”. This EEPROM’s power supply is 3.3V. If TV panel does not respond to
software update, it should be changed.
IC700, IC701, IC702, IC704, CAT24C02TDI, HDMI EEPROM
33
February 11
TF CHASSIS / TELEVISION
EEPROMs contain information related to the ports which are used to input video and
audio inputs. For instance, they may contain resolution information of the system.
Eeproms used in the positions of IC700, IC701, IC702 and IC704 are also used for
the inputs of HDMI1, 2, 3 and HDMI4. EEPROM contains HDMI resolution info and
protection password for HDCP, or HD broadcast copy. If it has a failure, copy
protected HD broadcasts cannot be received.
34
February 11
TF CHASSIS / TELEVISION
IC901, M24C32, CAT24C02TDI, VGA EEPROM
When VGA cable of the computer is connected to TF chassis, VGA EEPROM at
position IC901 contains the information about the supported picture format. The
broadcasts other than this resolution (for example 720P) may not be shown. Besides,
IC901 contains EDID DATA information where resolution data of TV and PC which is
connected from VGA input are compared.
IC1005, IC608 STMPS2151/2171; USB Power Supply IC:
It is the integrated circuit that switches USB voltage and limits USB current. Data
lines in USB socket are directly connected to main integrated circuit.
35
February 11
TF CHASSIS / TELEVISION
In the products whose USB option has been turned off from the service menu, the
socket has "service only" label and it is used for only software update. IC608 is a 1A
integrated circuit and can support hard disks (Side USB).
IC105, IC106, W25Q16BVSSIG, Boot Loader SPI FLASH
Similar to SX and SU chassis, TF chassis has two types of software. Similar to BIOS
software on the computer, "Bootloader code" starts to operate as soon as TV is
energized and ensures the functioning of system software. Bootloader code software
is stored in SPI flash, which is used on IC105 and IC106 positions. Currently, TF
chassis has SPI flash on IC106 position, not on IC105.

9.SERVICE MENU SETTINGS
To enter service menu, just like in the previously launched products, we press menu
button of the remote control and enter 9, 3, 0, 1 in sequence for BEKO/ARÇELİK
brand TVs. For GRUNDIG brand we enter 8, 5, 0, 0.
As the chassis improvement and development works go on throughout the
production, service menu items may vary according to the software version. The
following explanations are service menu settings of the current version.
System Configuration:
37
February 11
TF CHASSIS / TELEVISION
This menu contains general settings of the system.
TV MODE tab contains "Factory" and "Customer" options. It is used to perform
factory controls and settings more efficiently and faster. On the TVs delivered to the
customer, this setting is absolutely selected as "Customer." Otherwise, it will lead to
customer complaints such as "TV automatically turns on after power failures" or
"different functions operate from the remote control".
HDCP VERIFY: It must be checked if HDCP key is loaded or not during factory
controls. HDCP key stands for ““High Bandwidth Content Protection Key”. This key
is used to prevent copying of data on digital sources such as DVD or blue-ray. With
HDCP, video data is transmitted from the source to the receiver as encrypted.
Therefore, to watch HDCP encrypted DVDs or blue-ray, HDCP key should have been
loaded on TV. On the products with HDCP installed, SUCCESS message is included.
DEBUG MODE is a feature, which is used to track software modifications made on
TV during R&D stage. This setting must be "Off" on TVs delivered to the customer.
PLUG PLAY (Demo Mode): A navigation key is pressed after having completed all
settings and checks in the factory. Later, "Please wait" message appears; and when
you see the message "DONE", the device should be unplugged and plugged again.
With this process, television will be set to its initial values before delivery. It will be
proper to set Plug&Play tab after servicing. After pressing right key on the tab,
EEPROMs will be loaded with factory defaults. TV can be shipped to the customer
after this setting. Please note that any warning is not displayed or you do not have to
exit the menu while Plug&Play is getting activated. You should be careful not to take
the device into Plug&Play mode by mistake.
ATS (Automatic Tuning System) tab ensures that the channels are arranged in order
after automatic search. However, there is a broadcast support to order the channels.
It is active when “On” is selected. “On” should be selected in TF-chassis products.
SRS (Virtual multi-channel sound system) turns on and off SRS Tru-Surround XT HD
feature. SRS Tru-Surround XT® creates a sound experience surrounding the user
similar to 5+1 sound systems, thanks to multi-channel audio by using two
loudspeakers produced by SRS company. SRS is an optional feature that can be
selected upon the customer’s request.
BLUE BACK enables us to determine background when there is no picture on the
screen. When "On" is selected, background will be blue; and when "Off" is selected
background will be black or snowing. “On” should be selected in GRUNDIG brand
products and “Off” in other products.
HOTEL tab should be set to "On" on hotel TVs, and it should be set to "Off" in other
products. When the hotel model is "On", certain features designed for the hotel use
are activated; the user cannot change the channels set by the service, for example, or
the volume cannot be increased more than a certain level.
38
February 11
TF CHASSIS / TELEVISION
CI KEY VERIFY indicates if CI Key has been installed or not. This menu cannot be
changed. This option should appear as “Pass” in the products with CI Plus feature. CI
Key is the keyword on the card which is inserted to decrypt the broadcasting. This
menu is a control indicator and changes automatically. This keyword is installed
during TV production and it becomes a kind of ID for your TV when watching
encrypted channels. TF-chassis products support CI+ feature.
Launched in 2008, it is a new encryption standard developed with the collaboration of
consumer electronics and scrambled digital broadcasting companies. So far, it was
possible to copy the programmes after decoding process; however, now they cannot
be copied thanks to that main IC coming with the CI Plus has a key. In this system,
broadcasting is initially decoded on CI card. The broadcasting transmitted to the main
IC from the CI card is also encrypted and it is decoded with CI Key, which is a
factory setting and different for each TV. Thus, there will be no free encrypted
broadcasting on the bare line and encrypted broadcasting cannot be copied. C+
feature is standard in all the products with TF chassis.
SOURCE Configuration:
The settings under source configuration tab determine which sources will be on and
which ones will be off depending on customer demands. In the small size products,
HDMI3 and HDMI4 are off in standard (NAVAIL); and the sources of DVD and USB
can be adjusted optionally. In large size products, DVD will be off in standard. In the
products with LOW feature, USB, HDMI2, HDMI3, HDMI4, AV2, COMPONENT and
DVD sources will be selected off.
TV Configuration:
39
February 11
TF CHASSIS / TELEVISION
This menu contains configuration settings of TV. We may select amongst the menus
that are being used and to be used on TV. These settings differ from the "System
Configuration". This menu contains the changes which the user can directly observe.

enter the numbers 2, 3, 5, 6 in sequence.
TUNER menu contains the tuner types that can be used on TV. TF chassis currently
works with “Alps” branded tuners.
DVBT2 (Next generation digital terrestrial broadcasting modulation) can be selected
as ON/OFF depending on the customer preference, in the countries that support
DVBT2 digital terrestrial broadcasting. DVBT2 is selected OFF in the products to be
used in the country. In our country, TRT makes DVBT2 test broadcasting in Ankara.
OSD Selection menu has "Grundig", "Beko", "Arçelik" and "OEM" selections. For
Grundig products, “Grundig” is selected. This selection adds Grundig sign next to the
user menu and remote control selection is “TP3”. TV brand should be selected in
Beko and Arçelik products. This selection is automatically “YB1187R” in the remote
control and several brand-specific menus are also added. For other brands, OEM
should be selected. If the product is "Grundig", you can enter service menu by
pressing "menu 8 5 0 0" keys. If "Beko", "Arçelik" or "OEM" is selected, you can use
"menu and 9 3 0 1" keys.
Note: In the smaller size (19”-22”) products with TF chassis, when Arçelik, Beko or
Grundig is selected under OSD selection tab, different remote control options will be
displayed compared to large size products.

TF CHASSIS / TELEVISION
USB RECORDING menu indicates the television's status of USB recording. It may be
selected On/Off according to customer demand.
REMOTE CONTROL menu displays remote control selections for BEKO, ARÇELİK
and GRUNDIG as stated in OSD Selection above. For example, GRUNDIG OSD can
support several different models of remote controls and all those models can be seen
under the menu. Selection of remote control may vary according to the customer
demand.
KEYPAD enables you to select which keypad will be used depending on the
mechanical structure of the product. 4-Key, 6-key, single-key and “Joystick” options
can be selected. If selected wrong, the keys will work in different functions. 6+1 (or
joystick depending on option) can be selected for large size products whereas 4+1 is
selected for smaller size products and single-key pad module is used for the products
with LOW feature.
L (SECAM L sound system) tab enables you to select "L" sound system, and it
should be "On."
MEMC stands for "Motion Estimation Motion Compensation." "On" should be selected
for the products that use only 100Hz panel.
7 SEGMENT DISPLAY should be selected "On" in the products with the indicators,
which mechanically display the hour on the front panel. (Not TVs with LED backlight
panel!!!) Generally, this feature is used on hotel TVs.
ECO TV option: When "On" is selected , eco standards-compliant power consumption
is ensured by turning down the backlight a bit. ECO TV option should be selected ON
for all products with TF chassis.
LINE OUT (LEFT/RIGHT Audio output): If the product has line out feature, it should
be selected “On”. Large and small size products with TF chassis will have LINE OUT
feature in standard.
HEADPHONE tab should be selected "On" if TV has a headphone socket. Large and
small size products have headphone sockets in standard.
SHOP MODE is used in the first installation at the dealers for purposes of display
(Shop Mode and Home Mode screens appear). When Shop Mode is selected, the
logos of various features such as CI+, SRS etc., which are supported on TV, appear
on top of screen with certain intervals. SHOP MODE should be selected ON for all
products. However, when the product is delivered to the customer, TV is switched
back to factory settings via PLUG PLAY; and HOME MODE is selected during the
first installation at the customer’s place. During the first installation, SHOP MODE is
only selected at the dealers for the purpose of display.
3D TV (3 Dimensional TV Technology) is not supported in the products with TF
chassis.
41

have been adjusted to prevent cabin resonance and ensure best audio quality.
Depending on the cabins, the list of cabin options that may take value from 1 to 7 is
constantly updated.
HIDEV MONO (improvement of high audio deviation), is a feature developed to
prevent imbalances that may occur on sound carrier signals due to high audio
deviation in the country. It is ON for domestic products and OFF for the products sold
abroad.
OPTIC OUT (Digital Audio Output) feature is generally used to input digital audio to
devices such as amplifier, DVD and etc. OPTIC OUT will be available on large size
products with TF chassis and not available on small size products and the products
with LOW feature.
Cloner Configuration:
This menu is used to copy your selections, channel lists, user options, satellite
settings and service menu settings on TV and move them to another TV. Particularly,
when installing TV at the user's home, this feature will save us time as we will not
have to tune satellite channels anew.
42
February 11

Cloning can be done from any TV with the same chassis. To enter this menu, you
should navigate to "Cloner configuration" from the service menu and enter the
numbers 4, 6, 5, 8 in sequence.
Copy selects what and to where we want to copy. TV to USB copies the configuration
on TV to the USB. USB to TV transfers previously prepared channel list, user and
satellite settings to TV.
Copy item is the name of configuration to be copied. Channel/Video Set selection
enables us to transfer channels, frequencies and favourite lists that were already set.
Service Set enables us to transfer service menu settings. When installing at the
user’s place, this option should NOT be cloned. User Set enables us to transfer user
settings (sound, brightness, TV language and etc.).
Start Cloning option starts the cloning process. Whereas TV to USB takes little time,
USB to TV causes a short interruption of TV imaging. When TV automatically restarts
after installation, its means cloning is completed.
NOTES:
When cloning, you should ensure that both product codes are the same. During both
TV to USB cloning and USB to TV cloning, “ALL" should be selected as Copy item.
When cloning between different product codes, only “Channel/Video Set” should be

11.FAILURE/ERROR CODES
11.1.Sound but no picture, and backlight illuminated
In this section, we will basically explain where we need to check if there is "no picture
on TV" even though there are not any problems in the panel inverter. Here, we are
assuming that chassis is generally in good condition as we obtain sound output from
TV. When you cannot determine if the backlight is working or not due to the
illumination level in the environment, you are recommended to tap on the TV's front
panel lightly; if the backlight is working, you will notice a slight glowing.
Before starting controls and repairs, it is crucial to analyse and comprehend the
problem exactly. In this problem, you must make sure if it is originated from the
utilized source, if it is a cable connection error or if utilized devices have any problems
or not.
Then, particularly LVDS cable on the chassis should be checked for any
disconnections, loose parts, dislocations, breaks or ruptures. Likewise, it will be
proper to check cable connections of the panel.
Later, the panel power supply (PANEL-VCC), which is transferred to T-CON board
through LVDS cable, should be checked on L609 for 100Hz products and on T607
MOSFET Leg 3 for other products. Panel supply for the products with TF chassis is
12V.
If this value of power supply does not exist, the root cause is detected by tracking
back from this supply.
Panel power supply is switched with T607 MOSFET (except the products with 100Hz
panel). Initially, the input - that is L607 coil - is checked for 12V. If not found in L607,
L608 should also be checked. If you cannot detect 12V supply here as well, then the
problem is on the power supply side. For the products with 100Hz, L608 coil is
checked for 12V. If not, then the problem is on the power supply.
If 12V exists at the input, check the voltage on T607 FET legs. When TV is “ON”,
3.8V voltage occurs on Leg 1 of FET as to be higher than 0V, and supply voltage on
Leg 2 is transferred to Leg 3. If Leg 1 does not have voltage, check "TCON_ON"
signal on Leg 8 of R654 resistance. Here, if the voltage is High, it means that panel
supply has not been turned on from the main integrated circuit or software. This signal
remains High while the TV is going out of Stand-By and gets down to 0V, 1 seconds
before the picture appears on the screen.
If the panel is supplied voltage over LVDS, it is most likely that picture information is
transmitted as well. Even it is not a precise control method to be used during
information flow over data lines, the measuring tool detects voltage around 1.2V DC.
In this case, it is likely that panel side has an error; if possible, it can be checked by
using a different panel or using the same panel with a different chassis.
50
February 11
TF CHASSIS / TELEVISION
Besides, you can also consider problems including that LVDS data is not being
transmitted to the panel properly, wrong panel EEPROM or software error. You can
solve the problem by installing correct software.
11.2.Sound but no picture, and backlight not illuminated
Even though LVDS data is printed on the screen, the picture cannot be seen because
the backlight is not illuminated. First, cable connections, particularly inverter and
supply cables and connectors should be checked.
24V power supply should be checked over inverter cable when TV is ON. When this
power needs to be supplied to the inverter unit of the panel, the backlight will not be
illuminated if there is not 24V supply. 24V and 12V supplies are switched on by
POWER_SW signal coming from the main integrated circuit when TV is ON. In this
case, if there is 12V output but no 24V output, then the problem rests in the power
supply.
If 24V supply exists on the system; on the Leg 5 of S606 connector, a voltage over 3V
DC should be transmitted to the panel. This voltage gives “switch on” command to
the panel inverter. This control is provided with “BL_CTRL” and T608 and peripheral
materials.
Besides, voltage level that determines brightness of panel lights through Pin 6 of
connector S606 should be higher than 3V. Brightness control may vary according to
the panel, however, it operates dimly around 0V and completely on around 3.3V.
Brightness control is done by “BRI_ADJ” signal coming from the main integrated
circuit.
When the "backlighting" tab is dimmed in the user menu, the voltage in the Pin 6 of
the connector decreases slowly.
If no problem appears in the checks performed at the chassis, you should consider
that the problem might be arising from panel inverter module or the lights.
11.3.No Sound
It should be checked that if other sources, cables and devices have any problems.
You need to make sure that volume has not been turned down from television
settings or mute button is not pressed.
If there is not any problems, check the loudspeaker cables and loudspeakers on the
chassis; fix the problem, if any.
Check if there is sound on the headphones socket. As an amplifier is used, the
headphones output is obtained by amplifying EAR_OUT_R, and EAR_OUT_L
signals which are sent directly by main integrated circuit through IC502. If you cannot
receive audio from headphones socket, those signals are checked from R505
resistor’s pin 1 and 7. If no signal is observed, then there is a problem on the main
integrated circuit. If signals are detected, you should check IC502 and peripheral
components against problems, and check IC502 supply and whether MUTE is
pressed on.
51
February 11
TF CHASSIS / TELEVISION
Besides, scart output of TV should be checked for sound. If there is no sound in scart
output, power supply of the integrated circuit at position IC800 and peripheral
components should be checked at IC800 input to detect AU_DAC0_L and
AU_DAC0_R signals which are sent by main integrated circuit. If you cannot detect
AU_DAC0_L and AU_DAC0_R signals at the IC800 input, it means no sound signal
comes out of the main IC. If the scart output has sound, the problem might be arising
from the sound amplifier or peripheral materials.
When there is no sound, the pins 2-3 or 34-35 of sound amplifier on IC501 position or
L504 is checked for 12V or 24V (Amplifier is supplied with 12V in small size products
and 24V in large size products). If you cannot detect power, power supply should be
checked against problems.
If the amplifier is being supplied with power, Leg 19 should be checked for 3.3V DC
voltage. We should suspect about main integrated circuit if there is no 3.3V. This
voltage drops down to 0V and ensures switching the amplifier off in Stand-By mode
(AMP_STB signal and main integrated circuit performs the control).
Sound amplifier has I2C communication lines to communicate with the main
integrated circuit. Roughly, the voltage level should be below 3.3V and variable at the
Pins 23 and 24. Here, the fixed 3.3V gets lower when data is being transmitted, and
thus, sound amplifier and main integrated circuit communicate. If this value is
constantly 0V, short circuit possibility should be checked where I2C line is
connected. Current version of the software should be installed against software
problems.
Pin 25 is the reset pin of the sound amplifier. This pin should be high (3.3V) during
the time when TV is on. This value might be measured from C544 condenser. If this
value is low (0V), RESET_OUT signal should be checked. If this signal, which can be
checked from R539 resistance, is low, you may suspect that the problem rests in
software or main integrated circuit.
If all these inspections don't give any results, you may suspect that amplifier
integrated circuit has failure.

If code installation has been successfully completed, TV will automatically turn on.
Shut down TV to remove the USB.
14.2. BOOT Code Installation From Service Menu by Using USB Memory
Boot code update can be performed on TV's factory or customer mode.
Boot code to be installed should be listed under “Target/MBoot/” in USB memory's
main directory with the name “mboot.bin”. Ensure that software that you downloaded
from the system has this folder and “mboot.bin” file.
67
February 11
TF CHASSIS / TELEVISION
USB memory is inserted to TV and TV turns on (without pressing any key), service
menu is opened from the TV. (After entering the menu, type 8500 for GRUNDIG
brand products and 9301 for others)
In Service menu, go to "Boot Code Configuration" menu. (Press green button in
service menu or OK on Boot Code Configuration tab)
In “Boot Code Configuration” menu's “Start Loading” option, boot code update is
started from left or right key.
If TV's boot code is not updated, "Fail" message appears next to "Start Loading" menu
item. If update is successful, TV automatically restart.
TV should never be shut down during code loading. If TV is shut down, boot code
should be installed by using Debug tool.
14.3.MBOOT Installation by means of DEBUG TOOL
This feature should be used when you encounter an error while loading boot code
from USB.
MBoot program of the TV is installed by means of Debug Tool over VGA via MStar
company's ISP TOOL program.

TF CHASSIS / TELEVISION
After selecting software (*.bin) to be installed, press AUTO button. In standard use,
the following options are recommended.
After completing the settings, please press "Dis Con" button of the program interface,
then turn TV Power Off/On, press "Connect" button within 1-2 seconds. In this way,
TV goes to ISP mode. Here, a message indicates that Device type has been
recognized. If not connected, root cause of problem should be inspected.
After indicating the location of software correctly from READ section, press "Run"
button to start installation. “Erase” process may take 45 seconds. If this process takes
too short after pressing "Run", it might be suspected that there is a problem.
“Verify” process is a must. If there is an error in writing process, most probably this
will be shown within the first 4-5 seconds; you may press "Stop" button before waiting
for the completion of Verify process.
If the installation is successful, "Pass" message appears .
After completing software installation, service menu settings (Eco Mode, Blue Back,
OSD selection, Keypad and TV inputs) depending on TV's features and Plug Play
should be performed before delivering TV to the customer. Plug Play is located in
System Configuration under Factory Settings (Service Menu).
If the programme does not run successfully, it might be resulting from the following
conditions:
There might be a problem in cables, converter or tool. Probably, TV does not support
USB memory that we are using. We should format USB memory with FAT32 system
and re-install software. If this does not work, we should try to install software using
another USB memory.
71
February 11
TF CHASSIS / TELEVISION
On the chassis, there might be a problem arising from components or soldering. On
the PC, there might be problem arising from USB hardware or driver.
The latest version of ISP Utility should be used. MStar Debug Tool driver should be
installed. In “Config”, I2C Speed should have the correct value. In “Device”, “WP Pin
pull to high during ISP” should be selected. If not selected, the software may not be
updated even though it seems to be installed. If Device type is not recognized even
after you perform the steps above, turn off/on TV from the mains.
!!! IMPORTANT NOTE
Before software installation, TV's service menu settings, user (customer) settings,
channel list and satellite settings should be stored in an external USB memory
device by means of USB cloning feature (USB cloning-TV to USB); and these
settings should be re-loaded on the relevant TV after software installation (USBcloning USB to TV)!
To enter this menu, you should go to "Cloner configuration" from the service menu
and enter the numbers 2, 3, 5, 6 in sequence. Examine Cloner Configuration section
in Service menu for detailed information.

16.HOTEL TV INSTALLATION
Under Factory Settings – System Configuration, “Hotel TV” selection should be
“On” to ensure hotel usage.
Hotel TV is intended to prevent hotel guests from changing TV’s channel settings
and turning volume up to disturbing levels for the environment. Therefore, “Source
Settings” tab is not shown in user menu.
We should open “Hotel Admin” menu to make source settings and determine the
highest volume that the user is allowed.
75
February 11
TF CHASSIS / TELEVISION
Cloner Menu will be displayed by using password “4,6,5,8” on "Menu/Source
Setup/Program Table". These authorizations enable you to perform channel settings
(Source Settings menu), maximum-minimum volume settings and whether TV will
remain on Stand-By or directly turn on (Hotel TV Settings menu). This feature turns
off after TV is switched to Stand-By.
The channels are tuned and favourite list is determined over source settings. In
customer mode, TV is turned on at the channel and source where it was turned off at
admin mode. This feature should be used to set TV’s opening channel. As an
opening channel, you may set the hotel's own advertisement channel with hotel's
videos or a channel advertising paid broadcasts. In customer mode, it is not an error
that TV is turned on at the same source and channel whichever channel or source
was open when turning off the TV. You should consider this issue before switching
TV to Stand-By in Admin mode.
When setting up hotel TV, the easiest and most convenient way is to perform all
settings on a single TV and copy the same configuration to other TVs by means of
cloning feature. Here, you should make sure that TV is turned off at the intended
channel after completing installation at the admin mode.
