We went to turn on our tv this morning and the Power On indicator light went from red, to green, and then a second or two later it went to red again. There is a message on the top saying "No Signal". We pushed the "TV" button, next to the "Source" button on the remote, thinking that someone had put in a DVD or something before bed. But it still said "No Signal, and the power indicator light was still red while the screen stayed blue.Help!
