Anyone know of a place that can repair PS3?

Trying to find a place that will repair, if possible.....a 2 yr old PS3 unit. It reads the disc then after 5 minutes, shuts down..gives message that it cant read disc and all play stops. Pretty aggravating especially since its hardly ever been used and now that my son shows an interest and brand new games have been bought, it cant even play a game!
If u have any advice, please send comments...thanks
