Can you post a picture of what the screen looks like? It could be convergence amps or a pincushion problem. The pic would help clarify the diagnosis.

Lots of Blue shadows off to side. concaved picture almost


HI, this is a failed convergence chip that is located on the convergence board. it will need to be replace ASAP. you can just replace the chip or , you can order a new board.

Replacing the chip can be a rough job if you don't have tech experience. if you are a fluid tech and you can solder and know your way around a circuit board, just replacing the chip will cost less. if you are not an experienced TV tech, i recommend a service call to the nearest TV tech to replace the convergence board.

PINK/GREEN SHADOWS, LINES


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:)
