4.3 Service Positions

For easy servicing of a TV set, the set should be put face down

on a soft flat surface, foam buffers or other specific workshop

tools. Ensure that a stable situation is created to perform

measurements and alignments. When using foam bars take

care that these always support the cabinet and never only the

display. Caution: Failure to follow these guidelines can

seriously damage the display!

Ensure that ESD safe measures are taken.

As most signals are digital, it will be difficult to measure

waveforms with a standard oscilloscope. However, several key

ICs are capable of generating test patterns, which can be

controlled via ComPair. In this way it is possible to determine

which part is defective.

• Video: Color bar signal.

the Customer Service Mode (CSM) is used for communication

5.3 Stepwise Start-up

When the TV is in a protection state due to an error detected by

stand-by software (error blinking is displayed) and SDM is

activated via shortcutting the SDM solder path on the SSB, the

TV starts up until it reaches the situation just before protection.

So, this is a kind of automatic stepwise start-up. In combination

with the start-up diagrams below, you can see which supplies

are present at a certain moment. Caution: in case the start-up

in this mode with a faulty FET 7U0X is done, you can destroy

all IC’s supplied by the +1V8 and +1v1, due to overvoltage (12V

on XVX-line). It is recommended to measure first the FET

7U0X or others FET’s on shortcircuit before activating SDM via

the service pads.

The abbreviations “SP” and “MP” in the figures stand for:

Constraints taken into account:

- Display may only be started when valid LVDS output clock can be delivered by the AVC.

- To have a reliable operation of the EEFL backlight, the backlight should be driven with a maximum PWM duty

cycle during the first seconds. Only after this first one or two seconds, the PWM may be set to the requir ed output

the picture should only be unblanked after these first seconds.
