I have a Hitachi 50UX7K (AKA 50UX7B & W). The set turns on, but there is no signal on any of the inputs. I hooked the cable directly into the antenna jack and the screen is blank. I beleive that the projectors are working, because I can bring up the on screen menus, just not any picture or sound. The TV was working 2 days ago and then we moved it into another house. I looked inside and all of the connections appear to be in tact, although I am no technician. Any ideas what could be causing the problem and how much it would cost to rectify?
Thanks in advance,
Matt
