I thought it just overheated also, after waiting a few hours and trying to turn it on, the PS3 goes from green to yellow to blinking red. A few attempts to get it started and now it won't turn on at all, no lights or anything.
My PS3 just got the 'yellow light of death' and now it won't turn on at all. I was wondering when you ship it to Sony, how long does it take for them to ship it back to you?
