Question about Mitsubishi WS-55511 55" Rear Projection Television

1 Answer

Convergence way off!

Hi!
So I had the green line issue as mentioned in this post
http://www.fixya.com/support/t371268-green_lines_upper_third_screen

I replaced the convergence IC, and the green lines went away, however now the convergence is way off, and it looks like a fishbowl.

Is there something else broken? Anyone have any idea?

    Also, the Pico fuses are all fine, none are blown!
    Also the Diodes in line with the fuses are fine.

    Any other ideas?

Yup, you lost convergence. The only fix is to repair/replace the convergence IC. Some techs will just replace the whole video board.

The green is out of line. i tried the convergence but its too far out of line, also the line is crooked.


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.

RCA 52 in HDTV red, green and blue colors not alligned - concave


That repair only repairs the issue of the convergence option missing from the on screen menu. If thats what your problem is then the ITC222A convergence option missing repair kit at the following link should repair the issue. The kit contains the fl231, DL231, CL230 and the CD with detailed instructions.
