1. Safety Precautions
I. Parts with the exception of MODULE
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. Pane 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 b ock (Main and Sub PCB) is Mu ti Media circuit board that can process various input signa s
such as video, component, PC, DVI, and ana og TV signa . It is main y composed of switching,
sync processing, decoding, ana og TV, digita image processing, and system contro part
4-2-1. Composite video, Y/C(S-Video) and SCART (CVBS, RGB) composite video
Y/C(S-Video) and SCART(CVBS) have simi ar signa paths, IC102 receives these signa s
and swithes out a se ected signa . Then the signa goes into IC132 for video processing,
SCART(RGB) signa goes direct y into IC132. The output of IC132 goes through IC134 and
IC140 for deinter acing and digita image processing respective y.
- Main IC
A. IC102: Switching IC (Input: ana og inputs Output: an ana og output)
B. IC126: Te etext IC
C. IC132: Video processor (Input: Y/C, CVBS Output: 16bit digita , HV)
D. IC134: Deinter acer (Input: 16bit digita , HV Output: 24bit digita RGB, HV)
E. IC140: Image Processor (Input: 24bit digita RGB, HV Output: 24bit digita RGB, HV)
- Main TP (Input: Co or Bar Pattern)

4-2-2. TV signa
Tuner(PC901) receives antenna signa and outputs CVBS and sound signa . IC102 switches out the
CVBS and the rest of the signa f ow is same as composite video signa f ow mentioned ear ier.

4-2-3. DTV/DVD signa
Both DTV(Y, Pb, Pr) and DVD(Y, Cb, Cr) share same jack and signa path. IC102 switches out
signa and a so detects type of signa so that IC121 can convert the ana og signa to digita . Then
the signa goes through IC134(deinter acer) and IC140 for digita image processing.
- Main IC
A. IC102: Switching IC (Input: Component Output: Component, HV)
B. IC121: A/D converter (Input: Component, HV Output: 24bit digita RGB, HV)
C. IC134: Deinter acer (Input: 24bit digita RGB, HV Output: 24bit digita RGB, HV)
D. IC140: Image Processor (Input: 24bit digita RGB, HV Output: 24bit digita RGB, HV)
TP188: Clock for display (output of IC140)
