IT TURNS ON BUT SHUTS RIGHT BACK OFF CAN SOME HELP ME FIX MY PLAYSTATION3

problem thermostat call a technician to properly diagnose and fix

Which model is it? or if you can find an option in settings to perform a reset try it. That should fix the issue.

While hard (fixed) drives are more tolerant today than a decade ago, they are precision devices and subjecting them to hundreds of Gs will wipe out sectors. I suspect the unit shuts down because the drive is no longer capable of locating the required files to start up.

check your game settings

ofcourse it turns red b'coz the battery is low ..u nid to charged it !

If it blinks a red light when it turns off this is known as they yellow light of death(ironic i know). This is caused when the unit overheats causing solder on the board to melt and bridge (connect). Once this happens it shorts out the board causing the error you have now. Contact Sony and see if the unit is still under warranty.

Your motherboard is damaged I would send it to be repaired.

Power Light Shuts Off
If the power shuts off during game play (even as much as 30 minutes after the system is turned on), then turns off and won't turn back on or the fan isn't working, the system needs repair.

Power Light Flashes
If the power light flashes once when power button is pressed, then turns off and won't turn back on, the system needs repair

Replaced YDRVTP & YSUS CBA's. Worked.
