You need to replace both convergence ICs STK392-120 they are an easy repair you will also need (4) 6.8ohm Convergence resistors. You can get replacement ICs and the resistors at the following link and they will provide free installation instructions and free on line tech support so you will be able to do the repair yourself and save about 400.00 for a 45 minute repair. heres the link.

SOURCE: It started separating the blue from the red so you see everything in double. and the color is not right

You need the panasonic convergence repair kit #1 which comes with instructions with pictures. Heres a link to the correct kit for your model.

SOURCE: My Toshiba cinema series HD separates the red & blue color.

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...

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....

I have a Sony Color Rear Video Projector Model KP-57HW40. Its blue color is not working anymore and noticed some burn smell by the set which controls such blue color.


It may be the CRT drive board which is attached to the bottom of the Blue CRT. I would check that Board for signs of being burnt it may need to be replaced.
