Has wavey lines and horizontal shadows and will not complete auto focus. It happens after the tv is on 10sec. Have adjusted and cleaned the picture tubes did help clarity but still has the problems


projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

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 projection 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 pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

Double Vision & Bowed Screen


Chances are that the convergence amps are bad.
If those are mounted on a separate board, replacing the board would be the easiest thing to do. Running the magic focus or touching up the convergence in the customer menu may be required.

CONVERGENCE OUTPUT I.C.


Nextag and eBay are turning up nothing for this model. In comparison to other manufacturer's prices, the quoted price is not "unreasonable." Projection TV repairs are certainly not cheap. Sorry.
