Had to send my PS3 back to Sony. Once it got up to temp, it no longer would recognize that there was even a disc inside. So it would only let me play for 20 minutes before locking up. Next day after it was cold, same thing. Did a search and found it is quite common. They sent an email saying they received mine and are just sending me a new one by Tuesday. Moral of the story is, "keep your receipt", it's good for a year. They even delivered a pre-paid box to send it back to them in. Excellent customer service if this should happen to anyone here.
