I have a 27 inch SDTV by Sanyo. This tv seems to have a problem displaying white images for more than about 5 to 10 seconds. It will turn blue on the left side of the white image and red on the other side, eventually getting darker and really bad after about 30 seconds to a minute. This problem will still persist even if the contrast is turned almost all the way down. At this level you really can't see anything at all. I can't seem to figure out what is causing this problem. I always thought if white turns diffrent colors then that means the phospors are being overdiven and will cause CRT burn. But even at a very low setting it will still do this. If the contrast is all the way up it happens even faster. This does not seem to effect others colors only the color of white. Is there anything I can do to correct this problem. I am expericenced it electronics repair so If you have any type of solution I am all ears. Thank you for looking at my problem.
