Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)

This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

We cannot get the color to align. It appears like there is a blue or yellow background around words


If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

Magic focus --blue and yellow sag in the upper left area of the screen


This is a problem with the convergence circuit. If you can solder, you can repair this yourself. First try and resolder the pins on the existing convergence ICs. These are large black ICs attached to a heatsink and should be marked STKxxx. If the resoldering does not resolve the problem, replace the ICs.

There are integrated ic's that control the convergence circuit, it generally requires qualified service personnel to repair this.

Colors are separated on the top from the left to right


Probably the color convergence is off. I had a similar problem. Have you tried the magic focus button yet? That is located at left in the small front control panel. Power on TV, wait 20 min (according to user guide), then press the magic focus. If that doesn't fix the problem, you could try the service mode alignment procedure. But that's a little trickier. I don't have a link handy for that procedure right now, but will look for it if magic focus doesn't re-align your color convergence.

Double pictures!


Looks like you have a convergence/alignment problem. Try the magic focus (your instruction manual should help you with this). Or else, you will manually have to align the lamps.

If that still does not work, you may have to get the convergence IC's replaced.

Bad ghosting of all colours


The most likely cause is shorted convergence chips and possibly a few pico fuses.

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,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links 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
