Phones do not have a real power switch. The power switch is just a push button that activates a circuit. The circuit then connect the battery to the phone circuit. When released, the switch is open. Therefore, there can be many causes.
Power button bad.
Connection of button to MB bad.
Switching circuit bad. = this can be one of multiple components.
