Why is my Mitsubishi rear projection tv shutting itself off?

[Ashley]

We had a scheduled power outage, and when we came home we noticed our tv is shutting itself off every 10 minutes. It is a Mitsubishi rear projection WS-65315. I took the back off and got all the dust out, but that did not work. Sound and picture are great, it will not stay on though. Help!!!

Press the "Device/input" button at the same time as the "menu" button for 5 sec and read the two digit flashing code on the LED on the front of the tv.

Then add that number to additional details for this question.
