Sony did something similar for me for my PS3. It was out of warranty and the drive stopped reading Blu-ray discs. CDs worked fine. I couldn’t find the receipt to see how old it was but contacted them anyway. They said can I find an old bank statement or something to see if it is still in warranty. The only thing I found was it showed up in the loyalty points of the game shop I got it from. They accepted this as enough proof however the unit was out of the standard warranty. They said they will still accept it. They sent out a postal guy with a thick plastic box with foam insulation with a replacement PS3 in it. Great! All free of charge. I was well happy. Then a week later a letter arrived and contained the SD card that I accidentally left in my old PS3.

Sony went the extra mile here. Very happy with the outcome.
