Sony TV image rough, missing color depth and pixelation
My old Sony Bravia KDL-46V3000 TV suddenly started showing a picture that is quite a bit off. I don’t really know how to describe it. My best effort would be: rough edges, missing color depth and pixelation. But a picture says more than a thousand words.

I have searched quite a bit online and think it may be the t-con board that has a defect. Before ordering a new one I’d like some expert opinion. Does anybody know what might be the cause and how I might resolve this problem?
