Try the panel-check test patterns generated on the logic pcb. Will eliminate all boards 'cept the main pcb if patterns are displayed.

how would i do that downunder?
 cheers

downunder:
TV off.remove cable from p/supply to main board and cable from main to logic. Find PS-ON pin on p/supply and cheat it by linking it to ground.On the logic board find pins marked EXT GEN and short them out. TV on.
If p/supply and all scan circuits are operating normally, the tv will display clear test patterns. If it does, main is faulty. If it does not, back to square one.

mali67:
i cant find anything marked ext gen

downunder:
May not be on all models but very hard to find....I have to use a magnifying glass.
