I have a 32 inch older rca I bought it about 3 years ago so not digital. All has been fine with converter box and dvd/vcr and all until latley. Now on about half the time I turn it on I have lines running through the middel 3 inches of the scren. They will falten out to a single white line then expand back to a mix of black lines, I have all rca cables feeding into an rca switchbox. Then rca into the TV. The problem will sometimes go away or not happen at all, but will apear during various times of the day. Also it dosen't matter what source it happens with any one of them, even if they are turned off. Any info would be appreciated thanks in adavce.

Does this happen while viewing dvds or just while wathcing TV?

Happens during both, will do it with no souce selected just TV on(black screen), and will happen using any of the devices, converter box(tv), dvd, vcr.

Im no TV expert but if this is a tube TV old giant monster then my guess is its about time for a new TV. If it is not a tube TV post back and let me know. AC

Sorry was going to post this in the other one but got distracted. From what you described it sounds like the picture tube is on its way out. GOOD LUCK, AC
