Blair Hampson, seems to be a common issue with this model. This is from Panasonic regarding the 8 blink code

Symptom: Unit is dead with 8 blinks power LED.

Cause: Defective SS board, part number TXNSS1SDUU.


1. Identify three components on the board: Q16051, D16041 and R16051. Refer to Fig.1

2. Remove above parts from the board. Clean the heat sink and apply fresh compound.

3. Replace with new parts as follows:

• Q16051: DG3D3020CVLW

• D16041: B0FBCN000005

• R16051: D0GF5R6JA047

Inspect all grounding paths around mounting holes on the board and on the PDP panel area and carefully clean noticed arcing marks (Fig.2 and Fig.3) using sand paper with 400~1000 grit.

Of course, if you are not up to soldering those pieces, you can always replace the board.
