remove your hard drive...clean the connection....if that doesnt work...your hard drive is probably already gone
Try 1. Take your hard disk out and boot the PS3, 2. Then turn it off and put the hard disk back, 3. Re-boot again. If it doesn’t fix the red light try an extra step: 1. Take your hard disk out, 2. Turn it on to get the game out, 3. Put the hard disk back into PS3, 4. Turn on. DO IT A FEW TIMES.
