Degaussing means to demagnify. Not applicable with a projection tv. You have a severe convergence problem. Either a component failure, a speaker or other powerful magnet in very close proximity or someone figured out how to adjust (or misadjust) it.

The picture has colored shadows and doubled images. People are doubled shadows are red green purple. I would like to know if it worth fixing the tv is about Ten years old. Thank You

In a nutshell, the convergence ICs have failed. The cost to fix by a service company is likely about $300. You may find someone who does it on the side for around $150.

If you are happy with the picture, you like the tv, then $150 might be worth it.

It is possible to do this repair yourself if you have an electronics background.

Green and purple band of color

Projection TV sets have two very common problems listed below.

Problem #1) Convergence

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 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...

*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

Double vision on tv with purple and green colors


This television set, as well as most rear-projections, is prone to convergence driver problems. There are two large chips (STK392-110's) in the TV that need to be replaced, as well as some resistors that are likely damaged as well. Any competent TV repair shops should be able to repair this TV for 200-300 dollars. It is important to note that if the back of the TV is taken off without the proper prep., the Digital input (DVI) will be disabled permanently.

Hope this helps you...

My T.V. has a funny color .. more of double viewing with purple and green what can I do to fix this?

Your set has a problem with its convergence circuitry. In many cases this can be simply failure of solder connections to the output integrated circuits due to the heat they generate, and resoldering them fixes the trouble. This is a repair you might be able to try for yourself if you have experience with electronic soldering. Or there might be component failure which would require the equipment to isolate and replace the bad parts, which is a repair level best left to professionals. In some cases where the set has digital convergence, the failure might be in the computer control portion. This means the repair might range from only a very few dollars in parts to quite a lot of dollars, plus whatever labor rate the servicer charges. If you aren't looking for an excuse to replace the set, getting an estimate on a professional repair would be the best suggestion.

Degaussing is deliberately applying a magnetic field to the face of a picture tube. This is done to neutralize the effect of other magnetic fields that can cause color distortion. Degaussing isn't done in projection sets because they have separate tubes for each color.

Screen is bowed (top and bottom) Color has a green and purple tint?

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from and do the repair yourself. Its a fairly easy DIY fix.
