I've got a TV with the same issue as this one:
http://forums.cnet.com/7723-13973_102-356792.html

Ive got another TV of the same type which I can source parts from so Im just trying to figure out what is causing the issue. Ive already replaced the board that has all the inputs on it to no avail.

Thanks

Q2?

What do you mean by Q2? And no one knows the board thats causing the issue? I have spares of everything and could easily replace it.

Thanks

If you follow the forum no one has offered advice about boards or chips or parts. We see the occasional advice about the RPTV lamps but even then it's done with a disclaimer.

I think you are looking for a TV repair forum.
