Answers :

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) 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. In some cases the TV will also not show any video. 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....


\012
    \012
  • Screen looks 3D, wavy, or has a shadow or shadows \012
  • Colors don't line up \012
  • One or more colors can't be adjusted when using the convergence menu. \012
  • Screen is bowed or warped. \012
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
\012Here 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.

The colour on my TV is awful, the colours are not true at all. Red looks orange, blue is glaring blue and sometimes the colours fade out a bit and then come back. I have tried adjusting everything but nothing seems to help. I'm not sure if these TVs have "picture tubes" anymore but is there something I need to replace or do I just throw in the towel?

Hi, My Zenith DVD/VCR Model No. XB 713 skips through the dvds when playing. It has very low usage. I use my disk cleaner multiple times when this happens, which helps somewhat. I use a CD Laser Lens Cleaner (Best Buy said that this was "the same" as a DVD cleaner). Does the reader mechanism need to be manually cleaned? Anything I can do personally to get its performance back? I have the same system in my work room and that one has never given my problems. Thanks, Reachel
