Hi,

I have had similar problems with other brands, and it turned out to be the TCON board.

Hope that helps

Keith

Hi PRG,

Had something similar on a 26 Bush (Vestel) where I took in apart to find part numbers, Tried "Quuq parts required" - got no replies - reassembled set - then found pic OK.

Suspect in my case it was connections - all the best - Chris.

Hi,
One of my friends send me Tcon IC on T-Con board, which I replaced. Now original problem is gone, but there is excess brightness on picture. Hence black portion on picture can not be seen black but it becomes whitish -ve.
Any solution?
