Introduction

1. Basic concept of how to determine the defective board

1) Verification of voltages

Normally, when there is a power problem, shutdown occurs immediately.

So, to resolve a power problem, voltage checks are necessary before shutdown.

2) Check if the power comes up after disconnecting the board under suspicion.

If power comes up (*) after disconnecting a board, the board is defective.

(*) “Power comes up” equals “no shutdown”.

2. Troubleshooting Video and Audio problems

3. Examples of video problems

4. Adjustment after PCB exchange

1) After exchanging the following boards, voltage adjustment is required.

P board, SC board, SS board => Please refer to the “Service Manual”.

Troubleshooting Shutdown Problems

CAUTION: Some steps require removal of connectors and

sometimes PC boards removal. Do not let the TV run for more

than 30 seconds while connectors or boards are disconnected.


9/65Slide #9

Power LED’s Response to Shutdown Operation

When an abnormality occurs in

the TV, the “SOS Detect” circuitis triggered and the TV shuts

down. The power LED on the

front panel will flash a pattern

indicating the circuit that has

failed.

If the power LED continues to

blink even after the TV isunplugged, press and hold the

power switch on the TV for a few

seconds until the LED turns off.

CAUTION: Some steps require

removal of connectors and sometimes

PC boards removal. Do not let the TV

run for more than 30 seconds while

connectors or boards are

disconnected.

SU and SD Boards Isolation ProcedureBeginning last year (2008), the

plasma TV are designed not to turn-

on if either the SU or SD board isdisconnected.

Disconnecting either board causes the

unit to shutdown and the power LED

to blink 7 times.

Unplugging any of the connectors

SC41/SU41, SU11/SD11, and

SC42/SD42, opens the interlocked

connection between VF_GND andCHA on the SC board. This floats

point “CHA” triggering the SOS7

detect circuit. This outputs a high to

the A board through connector SC20

triggering shutdown.

A new SC test fixture (Jig) can be used when

the SU and SD boards are isolated. The jig is a

small connector with a jumper between pin 1

and pin 2. The part number is TZSC09187.

It plugs into connector SC50 on the SC board.


19/65Slide #19

Procedure to Isolate both SU & SD at the Same TimeTo isolate the SU and SD boards at the same time is not necessary to remove any

of the boards:

• Remove the 4 VF_GND screws (2 on the SU board and 2 on the SD board).

• Unplug connectors SC41, SC46, and SC42 on the SC board.

• Place the SC jig cable (TZSC09187) between pins 1 and 2 of connector SC50 on

• the SC board.

Note: If the SC jig is not available,

install a jumper between pins 1 and 2

of connector SC50 on the SC board.

(Remove the jig or the jumper after

completing isolation procedure).

When this is done, the display is

completely black (No picture)

Note: This procedure could be useful

when troubleshooting 7 blinks

problems.

SU Board Isolation Procedure

To isolate the SU board:

1. Remove the 2 VF_GND screws on theSU board only.

2. Unplug connector SC41 on the SC

board and SU11 on SU board.

3. Place SC jig cable ZSC09187)betweenpins 1 and 2 of connector SC50 on the

SC board.

Note: If the SC jig is not available, install a

jumper between pins 1 and 2 of

connector SC50 on the SC board.

(Remove the jig or jumper after

completing isolation procedure)

Note: This procedure could be useful when

troubleshooting 7 blinks problems.


22/65

Slide #22

SD Board Isolation Procedure

To isolate the SD board:

1. Remove the 2 VF_GND screws on the

SD board only.

2. Unplug connector SC42/SU42,

SC46/SD46, and SU11/SD11 from theSD board.

3. Place SC jig cable (TZSC09187)

between pins 1 and 2 of connector

SC50 on the SC board.

Note: If the SC jig is not available, install a

jumper between pins 1 and 2 of connector

SC50 on the SC board. (Remove the jig or

jumper after completing isolation procedure)

Note: This procedure could be useful whentroubleshooting 7 blinks problems.
