We have a Magnavox, I think we bought in the early 90's. From 90 to 93. It is a PIP (picture in picture). Lately when we have moved it into another room, plug it back in, it won't turn on. It has turned back on with the first two hours of repluging it, but this time it won't turn on at all. I checked everything in the troubleshooter section, plugs are just fine. What could be wrong? We haven't had ANYOTHER problems with this TV
