Last night we got some multicolor, green, yellow etc horizontal, kind of half moon shapes coming across the screen, removed the front screen and cleaned the lens's and mirror,, no change. Any Ideas?...

All 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.

Bad picture

Try to consider the following tips:

Smearing out of one or several colors, best seen in txt-mode, my 27CE4599/30R smeared out in red and green, not in blue, fully exchanging the drivers (input and output complete, otherwise the RGB driver will blank the crt) moved the fault to the other color
Replace the 180K feedback resistors in the amplifiers with normal 1/4W metal film instead of 1/8W, they can become open circuited (in mine both green and red were faulty in this way). Change all 3 and not just the defective ones, replace also all the paralleled 75K resistors per color (fe by 47K+27K) to prevent bright color raster (they can also become open circuit)
