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 note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

SOURCE: Sony 57 in Rear Projection TV
If the picture is playing fine and you notice that the background is getting more and more red, until it is too red and the set shuts down, it could be that the red screen control is set just a bit too high. If this is the case, you can probably correct this yourself. If you are watching a perfect picture and then it suddenly flashes a very bright red, with thin red lines in the pictureand then shuts down, it usually means that the red picture tube has developed a short in it, between the cathode and heater. A good tech might be able to remove the short by arcing, but if the short persists then the red tube will have to be replaced. Either way, this is something that should only be done by a qualified tech.
