I have a 5 year old Samsung plasma tv - model F8500 - and recently while watching television, it turned off- as did my cable box. The cable box immediately restarted but the tv was dead. No standby light - nothing. It was plugged into a power strip with surge protection and the other electronics plugged into it are fine. I tried plugging it into multiple wall outlets and a different power strip and nothing happens. No noises - lights - nada.

Im told (reading online and from my tech geek friend) that this television is the last great plasma of it's kind and only the new OLED's will rival it in terms of picture quality. I'd love to repair it if I can do it with minimal expense - which likely means trying to figure it out myself. I'm told to start with the power supply. Anyone out there have ideas as to what the problem is and/or what the likelihood is that the power supply replacement will fix it? I dont want to be dumping money into a television when I have no idea whether that will solve the problem.

Advice appreciated!
