Our HDTV (a Mitsubishi RPTV) is having troubles. When you turn it on, the power light will turn on for a couple of seconds, then just turn itself off. No sound of the guns firing up or anything else. Just a click when that power LED is lit, a pause, then it turns back off. I unplugged the set and replugged it elsewhere in case it was a power problem, but no dice. Anybody had this trouble before? I called the repair crew, we'll see when they can come out. Luckily, this was the one piece of electronics I took an extended warranty on. What a smart choice that was, used it twice and it's paid for itself 2-3x over. Any advice is appreciated.
