Question about Zenith A50M91W 50" Rear Projection Television

Green spot on the middle of screen.

I have a 1998 proj. tv Zenith model A50M91W, it has a green dot in the middle of the screen about the size of a dime. How can I fix this? Also what's the best way to clean the mirror, lensses and screen?. It was in storage in the garage and I think it is dusty inside. Thank you.

If the spot is perfectly round then most likely you have phosphur burn on 2 of the CRT's. If it uneven then maybe it is a spider who has made his home in there (not uncommon as it is warm and dry which is what they like).As far as cleaning goes, don't use standard glass cleaner as it will damage the screen. Use warm water and a soft towel, or purchase glass and plastic cleaner which is ususally a foam type spray.

D52w19 rca tv...has green screen..all crts seem to light up at the base but only green is on screen..also a looks like a burn dot in the middle of the screen.....sound works..powers on and off ok

The Green CRT has shorted and causing the green to become dominate is the most likliest cause. The Green CRT will most likely need replacement.

Converge off a little and screen has green tint

If you have the remote, go to the setup screen and move the picture. Converge has nothing to do with where the picture sits but, where the red, blue & green dots land. All you should see are pure white dots. There should be absolutely NO color ghost anywhere on the screen. If so, you need a bar / dot generator to set the convergence to center the dots.

Light green and pink spots on my hd tv!!!

Tiny particles of dust on the light engine lens can cause this (and was a service call for me about a month ago), or possibly the expensive light engine.
