Panasonic TC-P54S1 Revised Troubleshooting Handbook

Slide #18
SU and SD Boards Isolation Procedure
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.
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.
