    The TV is probably about 5 or 6 years old. We have had no problems up to this point. The color is real intense green and red and in between changing channels, you see redish/green columns appear until the channel comes in. This also occurs if we watch a DVD (I tried this to rule out the dish).

    Seems Blue gun is not working or has weak result.
    Capacitors in deflection circuits can also be weak.

My tv didn't turn green, but the red separated significantly. It started off happening after a few minutes of being on (I suppose the defective part was "warming up"), then it got to where it was like that immediately upon turning the tv on. In my case, I had to pay a tv repair man $350 for a new part. There are 2 microcircuits that control the color alignment--one that controls the red only, and the other controlls the other 2 colors, blue and green I believe. Maybe your part is the blue/green controller, mine was red. The repair man said these parts fail so rarely they don't stock the part. The cost of repair may be different for a different part, but either way you have to choose if it's worth that cost to you. If you get rid of it, I'll buy your tv stand ;-), I bought mine from a friend and didn't get the stand in the deal.

My Mitsubishi WT-42315 is almost like watching tv with 3d glasses on with the way the colors all seem split. Once in a blue moon it won't do it. But only for like a minute or so. What can I do to try and...


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.

I have a mitsubishi wt-42315. when i turn it on it shuts down right away. any thoughts?


Do the self check this model has.

When you turn it on and green power light goes out:

on front of set press and hold both the menu and input (or device) buttons at the same time for at least 5 seconds and release both buttons.

The power light will blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know what error code you find and I will tell you what problem is.

If this helped rate this solution as very helpful as I do this here for free.

I repaired a convergence problem on this model by locating IC8C01 and IC8C02, the two large convergence chips on the main pcb(center board) and solder all the leads making sure not to leave any solder bridges! The unit was over 4 years old and used often. Those chips get pretty heated and make the solder brittle and crack around the leads.

Red and green lamps look off center


Intermittant convergence alignment issues are quite common.
Either solder the convergence IC pins or better yet , change out
the IC's with first quality OEM spec or upgrade..............T.
