Hi
I could do with some advice.
Ive got a 55ub850v tv which turns and stays on, with backlights and sound but no picture.
The fuse on the the tcon has 11.78v on both sides.
There is also voltages on I assume test points at the bottom right hand corner of the tcon. There is also voltage present on the bottom left corner which fluctuate.
I have checked the (as much as I can) the components on the screen boards. They seem fine.
The psu output voltages are fine. The chips on the tcon is not very warm- whilst the main chip on the main board is hot-ish.
I was wondering if anyone could advise on what to check next or what they suspect is faulty?
I was going to change the main board.
Thanks in advance
