Hitachi 50ux14b My tv has sound but no picture. The menus show up on the screen but no picture from any of the inputs. Every once in a while it would work for a few seconds but not anymore. After reading some of the problems others have reported I think the HOT is bad, my conclusion to this is mearly because it appears as if it should be warm or even hot during operation and its cold, even after hours of listening to my set. My question is could there be a power imput issue? it appears as if it gets its power from the circut board. Any help would be greatly appreciated. thank you.
