When I turn on my big screen, I see the input channel (Input 1) in 2 lines: one line with red letters and one with green letters. I supposed my blue light is out, but it might be something else. How much...


This sounds like a convergence problem.

In the customer menu with the Mitsubishi remote select convergence and then advanced. You should see a grid of lines yellow in color.

If red or blue lines appear and are skewed and out of place you have found your problem.

I have step by step start to finish instructions for this type of repair in MOST OF THESE MODELS.


Let me know if it looks anything at all like the attached photos.

Alghin red green abd blur colors


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai2_bing.gif,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Your set has a convergence problem which is a common issue.

Take a look at this solution posted earlier on Fixya. It worked for me.

Blue is distorted


Find and examine the conv ICs, on their big heatsink. They may be unsoldered down at their legs, or need replacement.

Convergence Problem?


Convergence problems are what you have possibly a pincushion error. Either way if you have to have a repair shop do the repair, you should look at replacing the old TV.

Good Day, bigjim;

No inner tube. The tube may light up but it no video bias to turn the tube on, or the tube is so gassy that it doesn't emit properly.

It sounds like you will be in the market for another TV, because it sounds like like the CRT may be bad.

Hope this was helpful and not tooo late.

Good Luck, big IRISH.
