Hello, My HDTV panasonic 1080i is about 7 years old. I replaced the lamp about 2 years ago at 10k hours. Today it keeps powering itself off. It come on with the picture and sound for one full minute then powers down with the red light blinking.

I would suggest Googling the diagnostic code procedure. I would offer you three suggestions: your lamp is toast, your ballast is toast, or you have a failing fan. Diagnostics blinky codes will tell you.
