Take a look at the gun at theback of TV. if you don't see the beam. it is definitely the HV. I don't know it is worth fixing it. then, there may be something else is going too.

I did it once it is just not worth the time and money.

I have mitsubishi vs-50800 i was watching a movie and the screen just all of a sudden went blury and the color is all mixed up i went to the convergence menu and it wont allow me to move the colors left or...


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....


  • 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.

If you changed the Ribbon cable and its still the same then the T-Con board would of probably gone faulty. Lots of weird screen problems can be accounted for the T-con board.

Power but no picture


the Y-SUS BOARD is for picture in tv.if the picture is not coming or not proper the Y-SUS board needs replacing .but if the picture is blurry or with linings reparing helps.but in your case the tv does not turns on with y-sus board connected only error led comes on.this means y-sus board needs replacement.
you can get it from www.partstore.com

if you are not familiar with replacing the y-sus board its advisable to get it done by local tv repair technician familiar with your brand/model.

This will help. Thanks please keep updated.please do rate the solution if helped.thank you for using fixya.
