I have a 52GW947 and after 20 min it died and lights flashing in the back?

I had watched the 52GW947 tv for 20 minutes and the tv died and a flashing of light was in the back to the left of where the power cord plugs into. It has 2 red cables comming out of it and thats where the flashing is happening. It happend for about 10 seconds after it died also. Later tried to turn on and got just the flashing agian. I unplugged it and went to unplug the red plugs to take in the part and it shocked me. I want to see what this is so I can fix and tell me how. I also have a picture of the part of what Im trying to explain. Thanks for any help.
