Good Day, lawrentzsca;
Sounds like bad convergence IC’s, chips. Hit recommends using STK392-150’s and replacing the bias resistors.
Good Luck, Big Irish, but hope the TV is fixed by now.

Picture is bowed at top and bottom picture perfect in middle of screen; colors seperating in corners convergrence is perfect


Projection sets have two very common problems outlined below.

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. The TV can also shut down when the convergence starts to fail.

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, RCA and others.


You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*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

WS-55809 - Video pinched in center, distorted, yellow/blue/red glow


This doesn't sound like a programming issue. I had a very similar problem about 6 months ago and I fixed problem. I had cold solder joint on the video power board. It was the board in the middle. The power supply was to the right. The video board had a driver with a bunch of legs. About 7 solder joint where cold or loose. I solder the board and my mitsu wide screen was fixed. Hope this helps.
