My TV is about 11 years old, it's a 32 inch tube Toshiba. It's a model CF32G50, manufacture date, August 1997, and the chassis number is TAC
9715.The distortion is sort of like half circles on both sides of the screen, with "rays" that "flutter". The middle of the screen is brighter, but can only really see that if I have a solid light color background, such as a webpage displayed, or a menu for the DVD player.
I could see the pattern at times even when watching regular TV when I first bought it. I called repair out twice after purchase and they couldn't find anything "off", so I had this problem the whole time I had the TV.
Now that I'm using the TV also to display my computer, it's really bringing the defect out, especially on static screens where one color dominates. Very irritating. Not absolutely sure, but I think my TV may have an automatic degausser built in. The TV has never been dropped or damaged, and I've had the TV in about 5 different houses now.
I linked a crude drawing as it's about impossible to take a decent picture of a TV screen, link below.
Any info helpful if it's something that can be taken care of reasonably easy. Thanks much.
