Way back in '97 I bought a refurbished 27" JVC TV for about the same price as they're going for now. I didn't expect it to last this long, but it's been doing well. Lately, the picture 'wraps' over the top of the screen. You can see an elongated 'phantom' of it in reverse. At first, it was only an inch or so, but now it's around 4 inches. I also thought it was a copy at first, but now I see that it's the actual picture, so it's like the top is cut off. Is there an easy way to adjust this, or is buying a new set an alternative to spending money to repair?
