Have you moved the TV recently?, if so the red can(Red source) in the back bottom of the TV may have physically shifted in its holder, this is common when a rear projection tv is moved, jostled. Take the back off, look at the three cans,Red, Blue, Green, see if they all look like they are nested the same, bet the red is shifted a little.Good Luck with it!

This is a very common failure on Projection TV sets.

• 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.

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,Pioneer 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...

So you are able to adjust? the crosshairs move left and right up and down. you might have to get a tech to adust it in service mode.

THE PROBLEM IN YOUR TV. IT'S THE CONVERGENCE. YOU NEED REPLACE THE CONVERGENCE STK'S AND AFTER THAT YOU NEED DO ADJUSTMENTS.
