The ps3 boots up when you hold the power button you can play games as normal but you cant shut it down via the power button.
The controller is used for shutting it down and i cant enter service mode as im planning to upgrade my ps3 hard disk and entering fsm is needed
btw i own a ps3 CECHG04 model
Try a new power board ask
if he has any and will sell one to you.
