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”.

Slide #8
Power LED’s Response to Shutdown Operation
When an abnormality occurs in
the TV, the “SOS Detect” circuit
is 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 is
unplugged, 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 Procedure
If the power LED continues to blink even after the TV is unplugged, press and hold the power
switch on the TV for a few seconds until the LED turns off.
Beginning last year (2008), the plasma TV
are designed to shutdown if either the SU or
SD board is disconnected.
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 and CHA 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.
Slide #18
Procedure to Isolate both SU & SD at the Same Time
If the power LED continues to blink even after the TV is unplugged, press and hold the power
switch on the TV for a few seconds until the LED turns off.
To 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.

Procedure to Isolate both SU & SD at the Same Time

Slide #20
SU Board Isolation Procedure
If the power LED continues to blink even after the TV is unplugged, press and hold the power
switch on the TV for a few seconds until the LED turns off.
To isolate the SU board:
1.
Remove the 2 VF_GND screws on the
SU board only.
2.
Unplug connector SC41 on the SC
board and SU11 on SU board.
3.
Place SC jig cable ZSC09187)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 when
troubleshooting 7 blinks problems.
Slide #21
SD Board Isolation Procedure
If the power LED continues to blink even after the TV is unplugged, press and hold the power
switch on the TV for a few seconds until the LED turns off.
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 the
SD 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 when
troubleshooting 7 blinks problems.

Slide #24
SU and SD Boards Visual Inspection
Check the ICs on the SU and SD boards for blown hole on the
surface.
Note: In some models it is not possible to check if these ICs are
blown because they use surface-mount heat sinks that are glued to
the surface of the ICs.
This is an
example of what
a blown IC looks
like
Slide #25
SU,SD, and SC Boards Resistance Test Procedure
SU,SD, and SC Boards Resistance
Test Procedure
Note: The result of the resistance test determine if the boards are bad, but it does not
determine if they are 100% good. For this reason, after performing a resistance test, we
need to further check the boards that check OK using another procedure.
Slide #26
SU Board Resistance Test (All Models)
Preparation:
Disconnect AC Power prior to making any disconnection or connection.
Wait at least 2 minutes before the removal of any connector.
Note: If the power LED continues to blink even after the TV is unplugged, press and hold the power
switch on the TV for a few seconds until the LED turns off.
Unplug connector SU41 and SU11. Remove the 2 floating ground screws from the SU board.
Procedure:
Using a digital meter
measure the resistance
between VF-ground
(Floating ground) and
pin 2 of connector SU41
on the SU board.
The normal resistance
should be approximately
2.1Mega-ohms.
Note: A low resistance
reading indicates a
defective SU board.
Slide #27
SD Board Resistance Test (All Models, Except TC-50PX14, TC-P50C1, TC-P50X1)
Preparation:
Disconnect AC Power prior to making any disconnection or connection.
Wait at least 2 minutes before the removal of any connector.
Note: If the power LED continues to blink even after the TV is unplugged, press and hold the power
switch on the TV for a few seconds until the LED turns off.
Unplug connectors SD42, SD46 and SD11. Remove the 2 floating ground screws from the SD board.
Procedure:
Using a digital meter,
measure the resistance
between VF-ground

on the SD board.
The normal resistance
should be approximately
2.1Mega-ohms.
Note: A low resistance
reading indicates a
defective SD board.
Slide #28
