Re: picture problem

This smudge do the colors look ok, or are they starting to separate? If so it may be a purity problem, might try to degauss the screen, some AC electric drills can do this.

I have. Toshiba Regza 46rv530 TV that has been fine but now is only showing picture in top left corner of screen. I can't change to full screen using remote. Picture stays full while Comcast X-1 box boots...

Sounds like T'Con board fault.

Smudge looking marks onscreen

If you suddenly noticed it, this is most likely caused by a large piece of dust on the lens. It is hard to clean, you would need to take the whole TV apart in order to get to the lens (mounted on the optical block).

It could also be caused by a failure of the optical block, which had inherent issues. There is a pending class action law suit against Sony for problems with optical block that include smudges, hazes, and tints that appear after a certain number of hours.

Other causes could be a dirty portion of the mirror or a smudge on the inside part of the screen but these are rare because dust and contaminants do not usually accumulate on these parts of the TV.
