We have a Panasonic TV model TH-50OPX60U which after being used for a while starts to break up. We can still see color and a bit of what's going on but it is jerky with horizontal lines and unwatchable. Sometime the Time Warner sign "This Channel Currently Unavailable" comes up but switching to other channels shows the same behavior or pattern. We purchased the TV in Jan 2007. Our other (newer) Time Warner hooked up TV doesn't do this.
