try and obtain a service manual, there may be some fusible resistors.

Hi Buggsy,

I think I have an identical problem with my TV (power board's dead). Although I do not know what tests to do to find out which component may be brokem.

I was wondering if you could let me know where you got your strw6525 ic from? Having trouble buying a replacement.

Cheers,

Toby
