TV electronics are complicated and if you do not have a circuit diagram for your model TV or electronic training then you need an electronic TV repair man/shop to repair your TV.

1996 mitsubishi 40" tv has a black screen and


no pic at all usiually means the the heater element in the picture tube it self is burned out. Also there could be a problem with the internal power supply that gives electricity to the heater element. These are all thing the cunsumer cant fix. You either need to trust ONLY a certified Mitsubishi TV repair man, or replace the TV.
I know it's not great news, but if this advice helps, please give me a good rating.

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. Repair kits with instructions are also avail from www.TvRepairKits.com

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.

This is a problem with the vertical circuit. Most likely one or more capacitors in that circuit have drifted in value enough to effect the picture as you describe. If you can update this with the make and model, I may be able to list the probable parts that need to be checked.
