The television shuts off after being on for 30-60 seconds. Thank God it is happening while still under warranty. Is this something simple that I'm missing? When it goes off, the red (on) light actually blinks twice every few seconds. I'd appreciate any help anyone can provide

The first thing in this unit is to check the ribbon cable that goes from the front control panel to the back ssb board, I would unplug and replug to make sure seated properly. Then try it again. There are alot of screws to take out but worth it if this solves the problem.
I just had the same problem with mine (Toshiba 42HP85) The TV was fine and shutoff red light blinked twice, and you can turn it on agin right away then it shuts off again. The problem was there are 2 cooling fans you can here at the top rear of the unit, when they get dusty the bearings wear out and shut off. See if you can here 1 or both fans working. If only one is on, you can get a replacement from coolguys.com for 7.95 ea. model # is on the back of the fan. Replace both while you have the cover off, if that's the problem. The unit shutting off is the computer sensing there is a problem the red light is an error warning. Good Luck!
