Hello,
I doubt if you'll find a schematic for this power supply.
A common fault for what you describe is CX810, a blue,
47nfd 1250V polyester capacitor (they usually split).

Hi John,

Notice that all three Quuq former 'Blue Super Heros' seem to have expired, would suggest that you, as a non crap, totally useful guy should get the Blue helmet.

Just a thought, though expect Wales to soon go for the Euro.

Hello John,

Thanks for your Post, i check the CX810 on my board. it seems to be ok. can it be that the failure is in the Standby PS? does anyone have a schematic for this PS?

Regards

Hello everybody,

i want to give an update. In my case the failure was the logic board, there is a short circuit on it from 5,3 volt line to ground. Replacing the board fix the problem and the TV works fine.

Thx for all who help..  :08:
