Where do I find safe mode?
1. Connect the PS3 to any display preferably using the HDMI output.
2. Connect the PS3 to a power source. Also make sure the PS3 is off and not started.
3. Hold the Power On button until you here a beep which should take no more than 7 secs and also resets the video settings BUT DON'T LEAVE PRESSING THE BUTTON. After almost 5 secs you will hear another beep. Now leave the power button. Your PS3 is shut downed now.
4. Repeat Step 3 once again , quickly.
