The convergence IC's are definitely bad. They are not a plug-in device, they solder in so this is a big job.

Picture is bending at the top and bottom and looks 3d


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. 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, Zenith, and others. You can get a convergenece repair kit wiith 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 - makes a chirping sound.
Problem #2

Your TV may have one or more of the following symptoms....
  • Dull looking picture

Red convergence way off


Hello,
I had the same issue as you pretty much exactly and so do others right around this last few weeks so I am thinking that this is a common problem with the product itself.

You can fix this pretty quickly with the link below. I bought it and it resolved the issue.

Auto focus not fixing blue shadow


Well now the convergence IC's need to be replaced. they are two black IC on a metal heat sink and they start with STK on them. If you dont understand the schematic, dont attempt this repair by yourself, as you have to unsolder the old ones and resolder the newer ones back in. Also you may have small fusable resistors that went out also if the iC shorted out. Also the heatsinks need heat grease on them. seek out a pro to assist you in this repair.
