1. Safety Precautions
1. Safety Precautions
(1) When moving or laying down a PDP Set, at least two people must work together. Avoid
any impact towards the PDP Set.
(2) Do not leave a broken PDP Set on for a long time. To prevent any further damages, after
checking the condition of the broken Set, make sure to turn the power (AC) off.
(3) When opening the BACK COVER, you must turn off power (AC) to prevent any electric
shock. When PDP is operating, high voltage and high current inside the Set can cause
electric shocks.
(4) When loosening screws, check the position and type of the screw. Sort out the screws and
store them separately for reassembling. Because screws holding PCBs are working as
electric circuit GROUNDING, make sure to check if any screw is missing when
assembling/reassembling. Do not leave any screws inside the set.
(5) If you open the BACK COVER, you will see a
Panel Gas Exhaust Tube (Picture. 1-1) inside
the bracket. If this part is damaged, the entire
PDP PANEL must be replaced. Therefore,
when working with the set, be careful not to
damage this part.
Picture 1-1. Panel Gas Exhaust Tube
(6) A PDP Set contains different kinds of
connector cables. When connecting or disconnecting cables, check the direction and
position of the cable beforehand.
(7) Connect/disconnect the connectors slowly with care especially FFC (film) cables and FPC
cables. Do not connect or disconnect connectors instantaneously with force, and handle
them carefully for reassembling.
(8) Connectors are designed so that if the number of pins or the direction does not match,
connectors will not fit. When having problem in plugging the connectors, check their kind,
position, and direction.

Description of A/V(MAIN and SUB PCB) and POWER
4-2. Overview
A/V block (Main and Sub PCB) is Multi Media circuit board that can process various input signals such as video, component, PC, DVI,
and analog TV signal. It is mainly composed of switching, sync processing, decoding, analog TV, digital image processing, and system
control part
4-2-1. Composite video, Y/C(S-Video) and SCART (CVBS, RGB) composite video
Y/C(S-Video) and SCART(CVBS) have similar signal paths. For the Main signal, IC102 receives these inputted signals and
swiches out a selected signal. Then the signal goes into IC132 for video processing, SCART(RGB) signal goes directly into
IC132. The output of IC132 goes through IC134 and IC140 for deinterlacing and digital image processing respectively.
However, at PIP mode, sub signal has a little bit different path from the Main signal. First of all, IC102 receives input signals
such as composite video, Y/C or etc, and swiches out the selected signal like as the Main signal. But the selected signal goes into
IC158 for video processing instead of going into IC132. Then it goes into IC140 for image processing.

Tuner(PC901) receives antenna signal and outputs CVBS and sound signal. For the Main signal, IC102 switches out the
CVBS and the rest of the signal flow is same as composite video signal flow mentioned earlier.

out the CVBS signal.

4-2-3. DTV/DVD signal
Both DTV(Y, Pb, Pr) and DVD(Y, Cb, Cr) share same jack and signal path. For the Main, IC102 switches
out signal and also detects type of signal so that IC121 can convert the analog signal to digital. Then the
signal goes through IC134(deinterlacer) and IC140 for digital image processing. On the other hand, Sub
DTV/DVD signal is swithed out in IC102 and goes into IC114 for A/D conversion, Then it goes into
IC140 for the image processing.

6. Adjusting Method
6-1. WHITE BALANCE Adjustment
1) Apply 5 Step Gray Scale pattern to Video input terminal (Pattern generator: MIK 7253S)
Figure 6-1 Step Gray Scale Pattern
2) Check initial data from USER CONTROL (refer to 5-1)
3) In order to start Service mode, press button in following order " Vol -> Mute -> Recall
(Display) -> Mute" of the remote control. And then select PW181-1 for checking initial data of
the SERVICE MODE (refer to 5-2).
4) Attach the sensor of White Balance Meter (CA-100) to the 80% white level of the screen.
5) Adjust White Balance by controlling R, G, B GAIN.
. Control R, G, B GAIN values so that the ranges are within DP (Default Value) 10. If the gains
are deviated from the range, the SET is disqualified.
. Set color coordinate to x=0.285 0.005, y=0.275 0.005, and the Color Temperature to greater
than 10,000 K.
6) Attach the sensor of White Balance Meter to 40% of white level on the screen
7) Adjust White Balance by varying the values of R,G, B BIAS.
. Control R, G, B BIAS values so that the ranges are within "Default Value" 5. If deviate from
the range, classify the SET disqualified.
. Set color coordinate to x=0.285 0.005, y=0.285 0.005.
8) Repeat from 4) to 7) until color coordinate is x=0.285 0.005, y=0.275 0.005, and then adjust
Sub Contrast for that the luminance is above or equal to 150 Cd/m2 when the sensor of White
Balance Meter is attached to 100% of white level on the screen.
9) To exit the Service mode, press Menu button of the remote control.
