You have a bad lamp fan. It is relatively easy to replace and something you could probably do yourself if you have any mechanical ability. The part number is 8-835-860-11
You can buy the part on Ebay factory sealed or Best Buy.Com has it also. To change the lamp fan you need to remove the rear cover. The lamp fan sets to the left of the TV as you are looking at the back and there is a metal shield over it. Take the 2 screws off the shield and the fan should come out. There are 4 grommets on each side holding the fan on.
