If they are large colored circles behind the picture scenes, mine had it too. Fix was as simple as service technician plugging into the EPROM and loading a software update. Picture then was better than day1.

Red, Green convergence lines are wavy

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

Letters and numbers are 3d and curved picture


red, green, and blue lines curve across the top of tv is cause by defective convergence STK IC or you have open resistor at convergence section. if you have defective RGB Color vertical ramp probably you have defective STK IC..

There is just three lines that show red, green and blue.

It has been my experience with Sonys that those three colored lines indicate that the set is having trouble with the data communication lines. The hitch is that a model as complex as that one has as many as five seperate clock/data lines and if any one of them goes down the set will exhibit your symptom. It will take a professional to track down which line is causing the problem. I've seen audio output IC's as well as tuners cause the problem.
