You have 2 IC's in the convergence circuit and possibly a micro fuse that needs to be replaced. Consult a local TV repair shop.

On left half of the screen [ KP51WS510 ], a redish shadow showing


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. 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, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV2_bing.gif may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

Color convergence problem


If you follow the instructions on the other thread, you should be able to resolve the problem. Try the simple stuff first. Resolder the pins of the convergence ICs and see if that alone resolves the problem. Sometimes that is all it takes.

Keep us posted.

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)

Sounds like a convergence issue. Call Sony for an ASC that can come out and give you an estimate. You are probably looking at $200-400 to do the repair.
