The exact same thing happened to me. I will never EVER buy Toshiba again. (Thankfully, one of my stepfather's co-workers fixed my problem for me)
I had something happen with my Toshiba happen too, luckily it turned out to be such a minor thing (the power input was loose) Best Buy fixed it for me, otherwise they said I would have had to pay - even though I'd -just- bought the thing.
In case you are wondering about other brands should need to buy, I have an ASUS and they have an excellent warranty, they honour and managed like a three day turn around for out of town service (they covered shipping). I was blown away.
