Sharp lc-c3234u 32" flat screen hdtv turns off and on

I purchased a new Sharp LC-C3234U hdtv yesterday, and it worked great for one day, until it suddenly shut off. It now turns on for about 4 seconds, then shuts off and restarts over and over. I unplugged it and plugged it back in, but same thing. I called support, and they asked me to unplug set, and press the power button for 1 min., then wait 5 min. before plugging back in. It worked again for about 10 mins., then did it again. What's up with that? it's a brand new tv! Please help.

    Purchased same LC-3234U from Costco, the on/off problem occurred after two months of bedroom use. Sharp C.S. did nothave a solution, suggested a warranty repair man.

    Exchanged the set at Costco for another one. Same probelm occurred after one day.

    The same problem happened with my set after just a couple of months of use. Costco's concierge service also recommended that one-minute hold of the on/off button. While it worked initially, after about 10 minutes of operation, the tv went back into break-down mode. It was then when I tried something I never would have thought of trying, it was just a spur of the moment thing.

    I simply disconnected the component cable from the tv and turned on the tv. It turned on and stayed on. I then plugged in the component cable on a different input (from input 1 to input 3). I've operated the unit for a couple hours now without any incident. I'd recommend you try the same thing and see if it works.

    The same thing...but kind of different. My sharp tv from costco has never turned off. It just has a hard time starting, i have to press the on button about 4 times, it goes thru its starting cycle, but finally will come on. The tv always stays on, and the picture is the best picture i have seen in HDTV

    i am using component inputs to the #1 input. 32" sharp aquos lc-c3234u
