Got My New Plasma Today!
--------------------------------------------------------------------------------
Well, after reading through this thread, I decided the 50pz700u was for me. So I ordered it from Newegg last week and received it today. Box was in good condition and so was the TV itself. So I plug it in and 2 seconds later, the TV turns off. I begin to wonder if I did something wrong setting up so I recheck everything, try different plugs, nothing works though. The set would turn off after 2 seconds and the power LED would blink 11 times.
I call the Panasonic Concierge service and they figure it's a power supply issue so they schedule a tech to come over and check it out, but not until next Monday. I was upset that after waiting for 1 week to receive the TV, I'd have to wait almost another week just for someone to take a look at it.
So I did my own research and discovered that 11 blinks means something is wrong with the fans. Sure enough, 1 of the 3 fans was not spinning upon power-on. With the TV unplugged, I noticed that the fan would not spin at all when blowing air on it using an air dusting can while all the other 2 would spin easily. So I used a toothpick to spin it a few times and loosen it a bit and low and behold, the fan came on and the TV works great! I haven't canceled the appointment yet just in case the fan acts up again, but all seems well now. So if anyone's TV shuts off and blinks 11 times, check the fans first
By the way, thanks to everyone that has contributed to this post. It provided a wealth of information for me!

Sure enough Xavier is dead-on the money-one of my fans is not spinning.
