You have possibly contaminated fluid in your blue picture tube if it has a hazy look.Blacks and whites look bluish and whites have a blue bloom to them.The other problem could be bad convergence amps.This would be double image around letters on the screen.

THE PICTURE ON MY TV IS SHOWING A YELLOW SHADOW ON ON SIDE MORE & A BLUE SHADOW ON THE OTHER. IS THIS A BULB PROBLEM?


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.

Blue and yellow shadows appearing on my rear projevtion tv


The convergence IC's are definitely bad. This is not something you can fix yourself unless you know how to solder and are technically inclined.
