This is probably a stupid newbie question but I'd welcome some advice. I really like this tv but I'm starting to think that the lack of an HDMI input might be a drawback in the future. As the tv consists of a separate screen and receiver, is it possible to swop the receiver for a more up to date version while keeping the screen? If that were possible, I'd then have a good looking screen and more flexibility for high def inputs etc. I'm sure it's not as simple as that, but I'd welcome some advice. Thanks, and great site by the way.
