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, IC102 receives these signals and swithes 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.

- Main IC

A.IC102: Switching IC (Input: analog inputs Output: an analog output)

B.IC126: Teletext IC

C.IC132: Video processor (Input: Y/C, CVBS Output: 16bit digital, HV)

D.IC134: Deinterlacer (Input: 16bit digital, HV Output: 24bit digital RGB, HV)

E.IC140: Image Processor (Input: 24bit digital RGB, HV Output: 24bit digital RGB, HV)

- Main TP (Input: Color Bar Pattern)

TP145: Brightness signal (input to IC132)

TP143: Color signal (input to IC132)

TP188: Clock for display (output of IC140)

4-2-2. TV signal

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

-Main IC

A.PC901: Tuner (Input: antenna signal Output: CVBS)

B.IC102: Switching IC (Input: CVBS Output: CVBS)

C.IC126: Teletext IC

D.IC132: Video processor (Input: Y/C Output: 16bit digital, HV)

E.IC134: Deinterlacer (Input: 16bit digital, HV Output: 24bit digital RGB, HV)

F.IC140: Image Processor (Input: 24bit digital RGB, HV Output: 24bit digital RGB, HV)

- Main TP (Input: Color Bar Pattern)

TP143, 145

TP181, 184, 187, 188

4-2-3. DTV/DVD signal

Both DTV(Y, Pb, Pr) and DVD(Y, Cb, Cr) share same jack and signal path. 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.

-Main IC

A.IC102: Switching IC (Input: Component Output: Component, HV)

B.IC121: A/D converter (Input: Component, HV Output: 24bit digital RGB, HV)

C.IC134: Deinterlacer (Input: 24bit digital RGB, HV Output: 24bit digital RGB, HV)

D.IC140: Image Processor (Input: 24bit digital RGB, HV Output: 24bit digital RGB, HV)
