To the OP, call Sony and ask. If your console is less than a year old it won't cost you anything (unless you caused it harm by neglect or misuse); if it's more than a year old they will tell you up front how much the repair/exchange costs will be and will require a credit card for payment if you decide to go ahead with the repair or exchange. They will then send you a coffin and a pre-paid shipping label so that you can ship your PS3 to them.
