No I didn't notice any blinking lights

Just to clarify, the TV actually turns on, and stays on for a few minutes, then shuts off as if someone turned it off?

Yes, it will turn on again after I push TV /power on the cable remote, but it turns itself off again in 2-3minutes.

Ok, well that is unfortunate...

 

The only problem that causes NO blinking lights at shutdown is a bad main fuse, or a bad DMD board. Since yours comes on, that rulesout the main fuse.

 

If it is the DMD board then usually the TV will stay on for a while, then just shut off on its own as if it was shut off, only the cooling fan won't run for the lamp.

 

If it were a temp sensor there would be specific blinking lights, same for the lamp, ballast, power supply, video processing. All have blinking light error codes.

Now you know why I said it was unfortunate Cry

 

 

Hope that helps in some way...
