Here is what I was able to find out about your problem from sony: This issue is usually caused by some type of nearby magnetic interference, such as unshielded stereo speakers placed too close to the TV. These spots can be small or large and will normally be red, green or blue, but sometimes appear purple or pink. They normally occur on the sides or corners of the screen, but can also appear in the middle. To resolve this issue, move any stereo speakers or other electronic devices away from the TV; a minimum of 2-3 feet is recommended. If the situation is not remedied immediately, unplug the power cord of the TV from the electrical outlet for 20-30 minutes; repeat this process one more time if the issue is not resolved the first time. If the issue is still unresolved, service may be required. The Sony® eService Web site at http://eservice.sony.com/ can assist you in obtaining service from a Sony Service Center or locating a Sony Authorized Servicer in your area. Hope this is helpful:)

Problem #1 - Failure in the convergence circuits. ( common problem )
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 will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.
