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”.

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.

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.

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.
