Sharp TV Aquos, skipped input needs to be restored.Input 3 was skipped accidently and I need to restore it. The TV is 7 yrs. old. Help please. I've already tried Menu, Options, but there is nothing there that will do the trick. Also tried a factory reset.
Some TVs will only allow you to access an input with an active source connected to it. If your TV just stopped accessing an active input there is likely to be a problem with the input board. Given the age of the TV I would suggest using an external input selector to expand one of the working inputs.
