ll 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.

DLP TV lamp went out, new one doesn't work either,


Well you have a Samsung TV, in this case, it's most probable that you might have an issuw with your ballast. It might not have enough energu to keep up with your new lamp. You might ask yourself, How could this be if it worked with the old lamp? Well the old lamp didn't have all of it's gases, like it used, when you recently purchased the tv or lamp, and as time goes by, those gases tend to go out.

Samsung 42 inch projection tv picture like watching coneheads seems to stretch


This is a symptom of a defective capacitor in the vertical circuit, but not usually with a DLP machine. Can you post the model number of your set please? I should be able to provide you with the part designation of the defective part once I get the model number.

Thanks,
Dan
