Question about Projection Televisions

1 Answer

I have a 1985 Zenith Space Command Color TV. It has developed thin white lines at the top of the viewing screen. The rest of the screen is clear. Is it something small or am I looking at a new picture tube. I hope it is something small because I love this old tv.

The picture tube is fine.
Those whites lines at the top of the screen are caused by a dry or leaky capacitor(s) nearby the vertical amplifier IC.
Let me know if you require further assistance.

I have a Zenith 65 in. TV model #R65W28 serial #271-33220211. The words are blurry and there is a green outline on images in the picture even if i reduce color to black and white. what can i do to fix it?...


It sounds like the convergence drive circuit has gone bad. When that circuit goes the red, blue and green don't line up properly. Have a repair shop check it out. While they are in there have the shop clean the lenses and mirror.

Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Zenith 60'' LCD TV a blue screen is not sky blue it looks dark blue to black


Go to zenith.com, look under the service icon at the top and then you should see a listing for "Class Action Lawsuit/Settlement". If you follow that link, they'll have specifics listed for this suit that was brought against them (including tv model #s included in the suit). There was an agreement reached to fix/replace affected t.v.s, court date was in Feb. I believe, and just waiting now until they post information on how to proceed.

Good luck and hope that helps.
