I have a Sony KV36FS70 TV and I often notice a slightly greeny tinged patch in the top right hand (and maybe left too) corner of the screen. It is only noticeable watching TV, not DVDs, and is most obvious when the screen is bright, i.e. white. It is just a small greeny patch in the extreme top-right corner. I am pretty sure it's not magnetic interference, since when I switch to Teletext i.e. dark black page, there is no lighter patch in the same corner. Any suggestions/ideas? Thanks guys!
