WARNNING

This service information is designed for experienced repair technicians only and is not designed for use by the general public.

It does not contain warnings or cautions to advise non-technical individuals of potential dangers in attempting to service a product.

Products powered by electricity should be serviced or repaired only by experienced professional technicians.

Any attempt to service or repair the product or products dealt within this service information by anyone else could result in serious injury or death.

CHAPTER C

SAFETY PRECAUTIONS

1. Caution

No modification of any circuit should be attempted. Service work should only be performed after you are through familiar with all of the following safety checks and servicing guide lines.

2. Safety check

Care should be taken while servicing this LCD display. Because of the high voltage used in the inverter circuit. These voltage are exposed in such areas as the associated transformer circuits.

3. Power supply requirements

The external power converter for this display utilizes AC and DC cords, AC cord is detachable, but DC cord is permanently attached. Any attempt to replace another adapter could result in serious problem on the display.

4. Leakage current hot check

4-1 Plug the AC cord directly into the AC outlet. Do not use an isolation transformer during this check.

4-2 Connect a 1500 ohm, 10 watt resistor, paralleled by a 0.15uF capacitor between each metallic part and a good earth ground.

4-3 Use an AC voltmeter with 1000 ohm / volt or more sensitivity and measure the AC voltage across the combination 1500 ohm resistor and 0.15uF capacitor.

4-4 Move the resistor connection to each exposed metallic part and measure the voltage.

4-5 Reverse the polarity of the AC plug in the AC outlet and repeat the above measurement.

4-6 Voltage measured must not exceed 1.5 volt RMS, from any exposed metallic part to the ground.

A leakage current tester may be used in the above hot check, in which case any circuit measured must not exceed 1 milliamp. In the case of a measurement exceeding the 1 milliamp value, a rework is required to eliminate the chance of a shock hazard.

ASIC FOS Performance (excluding Scaling Artifacts) will be judged according to:

Definition of “COMPATIBLE MODE”:

ASIC correctly recognizes the proper resolution and applies the correct display scaling to the image.

(I.e. a 1280 x 720 signal is properly recognized)

Definition of “PROPERLY SIZED / CENTERED”:

The Entire Image (use Display Mate “Side Tics” pattern) perfectly fits the screen. Even one pixel off in Horizontal or Vertical Direction, makes this area “FAIL”.

Definition of “PROPERLY PHASED”:

ASIC automatically computes the correct A/D response so that a Win98 “SHUTDOWN” or “ALL”

Display Mate “MOIRE” Patterns are correctly displayed. Most critical on the panels “NATIVE”; No

‘unstableness’ of the image shall be observed.

Definition of “HD Compatibility”:

The SP3243 devices feature ٛ circuitry automatically wakes up from . It occurs after a RS-232 cable being disconnected. Under this condition, the internal charge pump and the drivers will be shut down. Otherwise, the system automatically comes online.

10. Mitsumi MM1671 Low Supply Voltage 75 Ohm Driver

This IC is a 75Ω driver with a built-in LPF that can operate at low voltage. It supports 3V and 5V operating power voltage, and is ideal for video signal output in devices ranging from portable digital still cameras to stationary equipment such as DVD players. It incorporates a high performance

4-stage LPF, which is ideal for removing DAC sampling noise. In addition, ultra-low current consumption has been achieved b of the batteries in portable devices. The built-in amp gain on this IC is available in series: 6dB/9dB/12dB/16.5dB, thus enabling support for DAC and a variety of output amplitudes. There is also a series with input clamp and one without, allowing support for a range of video signals, not just composite signals.

11. EtronTech EM636165TS-5G SDRAM

The EM636165 SDRAM is a high-speed CMOS synchronous DRAM containing 16 Mbits. It is

Philips BDL46xxE 15

internally configured as a dual 512K word x 16 DRAM with a synchronous interface (all signals are registered on the positive edge of the clock signal, CLK). Each of the 512K x 16 bit banks is organized as 2048 rows by 256 columns by 16 bits. Read and write accesses to the SDRAM are burst oriented; accesses start at a selected location and continue for a programmed number of locations in a programmed sequence. Accesses begin with the registration of a BankActivate command which is then followed by a Read or Write command. The EM636165 provides for programmable Read or Write burst lengths of 1, 2, 4, 8, or full page, with a burst termination option. An auto precharge function may be enabled to provide a self-timed row precharge that is initiated at the end of the burst sequence. The refresh functions, either Auto or Self Refresh are easy to use. By having a programmable mode register, the system can choose the most suitable modes to maximize its performance. These devices are well suited for applications requiring high memory bandwidth and particularly well suited to high performance PC applications.

12. National Semiconductor LM1881 Video Sync Separator

The LM1881 Video sync separator extracts timing information including composite and vertical sync, burst/back porch timing, and odd/even field information from standard negative going sync NTSC,

PAL*, and SECAM video signals with amplitude from 0.5V to 2V p-p. The integrated circuit is also capable of providing sync separation for non-standard, faster horizontal rate video signals. The vertical output is produced on the rising edge of the first serration in the vertical sync period. A default vertical output is produced after a time delay if the rising edge mentioned above does not occur within the externally set delay period, such as might be the case for a non-standard video signal.

13. NXP PCF8563 RTC

The PCF8563 is a CMOS real-time clock/calendar optimized for low power consumption. A programmable clock output, interrupt output and voltage-low detector are also provided.

The built-in word address register is incremented automatically after each written or read data byte.

14. ST TSH340 Video Buffer

The TSH340 is a video buffer featuring a gain of 6dB. A large bandwidth of 300MHz for only 9.4mA of quiescent current allows the TSH340 to achieve a gain flatness of 220MHz. Its structure features a very high slew rate of 540V/µs minimum guaranteed by test. Associated to a very good THD these characteristics are particularly intended in the high quality video systems. The TSH340 is available in tiny SOT23-5 and SO8 plastic packages for size saving consideration.
