Question about Zenith A50M91W 50" Rear Projection Television

1 Answer

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.

Re: Green spot on the middle of screen.

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.

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!!!

You really need to be persistent. I went on the Panasonic customer support webseite and started a web exchange. The first two attempts ended with "call your local authorized service tech" , etc. The third time, I described the prolem again and asked if the authorized tech would have the tool to fix the eprom if that was the cause of the problem. They finally gave me a name for their scheduling department and said they would pay for the diagnosis. I was pretty happy about that, but even happier when they said that this was a known problem and they would pay for the repair as well. They scheduled a service call. The techs came and fixed the eprom error with their tool within 1/2 hour. That was about 5 weeks ago, and all looks good so far.

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

Hi--Bought my panasonic pt-52lcx65 on sale for $2200 in 8/05. Replaced the lamp for about $300 in 1/08, just prior to Superbowl. Admittedly, this was to be expected after family members watched lots of tv over 30 months. However, two months later the blue spot emerged in 3/08, and red spot emerged 5/08. Set looks decorated by a Andy Warhol or Van Gogh wannabe. I'm looking for a fix it solution. Dr. Bob Heiliger, Lebanon, OH.

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.

Green and Blue spots on screen

Sounds like stuck pixels, you really can't fix that. Do some google research if you are curious what a stuck pixel is.
