This is most likely a convergence problem. You should see 2 large black ICs in side attached to a heatsink. They will be marked STK392-010. Try resoldering the pins on these ICs first. If that does not resolve the problem, replace them. These parts will be about $20 each.
Keep us posted.

Picture and colour are distorted. There seems to be a wavy shadowing effect on the screen. Could it be the colour wheel?


Hi.

If the colors do not match, then it is the convergence.

Let me know if you want more information on this.

Regards.

Shadows on screen


Try moving a medium powered magnet (not one for picking up heavy objects and not a refrigerator holding one) over the distorted area. If that doesn't work, try a more powerful one. This worked for my Toshiba LCD. Good luck!

Projection sets have two very common problems.

The first common problem is 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

Coulor distortion at the top left of the screen


Hello jordan ashe,

This is an indication that the green CRT is having a convergence problem. This might be caused by the convergence amplifier or by the CRT. Does the rest of the picture look OK? and in addition can you supply a picture of your TV so as I can see what you are seeing and develop a proper diagnosis?


Thank you,
