Hmm, could you describe this better or post a pic? Try cleaning the lenses and disable SVM if it's on.

We have a Sony KP-57HW40 projection TV purchased around 2002. The screen fades to a blue and you can't make out the picture at all. What does this mean and can it be repaired?


This is one of a group of sets with bad picture tubes. If screen goes to mostly blue there is a way to attempt to get around it.

The tubes are expensive and only available on a rebuild basis.

I can tell you how to try in less than 10 minutes to adjust to compensate for the problem.

Do you want to know that to try/
