Convex red and blue lines looping at the top and bottom of the Screen

I have convex red and blue lines looping at the top and bottom of my screen. I have tried adjusting the convergence automatically and manually but it doesn't go away. It was barely visable but the lines are getting thicker and more prevalent as time goes by.Any help would be greatly appreciated!

The convergence red and green will not adjust making picture blurred. It looks like your looking at 2 pictures laid on top one another on a convex screen. Someone told me I may need a convergence chip......

Common convergence problem,both convergence amps need to be replaced and the 2 B+ fuses checked also all the fusible resistors around the amps, it should use stk392-040?

The reason their is no blue color in you projection screen picture.

Over time the Blue CRT in your projection screen produces a thin layer of fungal growth over the top of the tube. This attracts dust particles and as they collect they blocks the light from getting to your screen. This seems to happen with only blue CRT's. To clean it remove lenz and use a damp terry cloth with a water and bleach solution. Wipe the convex part of the tube untill it is free of all dirt and fungi. Replace lenz and get ready to enjoy a very sharp picture.

Rear projection - convex distortion / ghosting / expanding screen

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,Pioneer2_bing.gif 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....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

PT-61G63 Convergance

Your convergence IC's most likely need to be changed, possibly some resistors as well.
Do you know how to solder and use a meter? If so you may be able to fix this yourself for under $100. If not you will need to repairman to repair it, this should cost around $300-$500 Let me know if you want to repair it so i can get you going.

I suspect convergence ics part number startswith stks they are black and on a silver heat sink. if you could solder you could do it.If a tv shop fixed it the cost would be around 295.00. parts are 30.00 total. www.mcmelectronics has parts. to find out part numbers they are located on the board on the back.

Distorted image and color

sounds like the convergence ICs have failed. Will the red and blue move in all 4 directions when you try to adjust the convergence? If not the convergence ICs are bad replace both of them also check the resistors that power the ICs as they may be open as well.
