    re: 46 in. rear proj. Zenith TV:

    Picture is fine, except for the lower left corner - that corner has a round section where the convergence must be off becuase blue is off with the rest of the picture, creating a sort of 3D picture. Nothing else is impacted. I paid $900 new year ago, so if can't be fixed for $100 or so, time to upgrade. A new 50 in plasma 720 (not 1080) is only $900!

You need to replace both convergence ICs. You can get replacement ICs at the following link and they provide free instalation instructions as well as free tech support so you can do the repair yourself.

Color seperation


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Convergence problems


Well I would say the convergence amps are the culpits in your case. A common problem with all rear projection sets these days. Be real careful about buying replacements as I would go OEM only. They sell counterfits and low cost knock offs that will just frustrate you and raise the chances of damaging the board.
