Here are some of the most common symptoms and example photos of a convergence problem
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move them up, down, left, and right.
If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.

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.

Thanks for using FixYa. The issue is with the failed convergence (STK) ICs which needs to be replaced. It’s not a difficult job if you want to do this yourself, you should require some basic knowledge about soldering-resoldering components. To start with you’ll have to open the back of the unit and then replace the ICs (STK ICs) which are located behind the black heat sink and also check the resistors as if they are short the ICs might blow again after sometime. There are repair kits available which includes repair instructions with the parts, if you want to do it yourself, you can buy and repair it yourself.Please do rate the solution if the issue is resolved or post a comment for further assistance.
