Is My Pioneer PDP-5070HD Fried?

[BluPix]

So, I returned home this evening to find my Pioneer PDP-5070HD fifty-inch plasma display, which I've owned since January of 2007, mysteriously turned on. It was displaying a blank screen and hearing static. It was definitely off when I left for work this morning.

Just to make sure it was okay, I tuned it to a cable channel. Within fewer than five minutes, the TV went blank, clicking itself into standby mode for a few seconds, then clicked back on. It kept doing that erratically for a while. I unplugged it and all the other components my home theater system, then plugged everything back in and tried the TV again, but the problem persists whether it is tuned to any channel or receiver source and even even when it's not tuned to anything. It keeps flipping between being powered fully on (with a picture) and being in standby mode (blank screen).

Has anyone heard of anything like this occurring before? What could have caused this? Some odd power surge? (I've had the unit for over eight years and nothing like that ever happened. All my other HT components (receiver, PlayStation, blu-ray player, speakers, etc. seem to be okay.) What, if anything, can I do to fix this issue? Or is my only option to replace the display?

Not sure if this will help, but how long was it unplugged? A few years ago I came home and my 5080 would not turn on. After some serious freak out activity (unplugging, plugging, checking connections, etc) I looked in the manual and found that my Pioneer had a built-in surge protector that required the tv to be unplugged for two minutes to reset it. Now I unplug the Monster Surge protector whenever there is an electrical storm in the area. Could a power surge have fried something that powered on your set? I don't know if that can happen, but it couldn't hurt to unplug your set for awhile. Mine wouldn't come on, yours won't stay on. In any event, it's worth having a tech trouble shoot your set if the time out doesn't help. Good luck, please let us know what happens.

A long list of anomalies could create those symptoms. Symptoms say nothing about what is damaged or why.

For example, a manufacturing defect could exist. That is a most common reason for failures.

Another example. A surge incoming on AC mains found earth ground via an 'installed for free' cable protection. Damage being on a surge's outgoing path. Surges occur maybe once every seven years. Are incoming to everything. But only find an always required outgoing (and destructive) path via one or a few appliances.

Best evidence is a dead body. Without those facts (what is damaged), then every reply can only be wild speculation.
