I've been watching my Dish TV on Component 1. I've been using my DVD player on AV2. Recently, after watching a dvd, I tried to get to dish tv and I couldn't access component 1. When I push the "input button" on the side of the TV, the menu of components comes up and there is an "x" beside component 1, component 2 and rgb. When I try to scroll down to those components, they are skipped as if they are not available choices.I called dish tv. They checked everything on their end. My 2nd TV is working so I know the Dish signal is getting into the house. I also tried rebooting the DVR, but this did not solve the problem.One other thing, when I turn the Vizio set on, the message "pip no signal" shows at the top of the screen.Thanks in advance for your help
