i think u have eny of this problems

if the resistor R905 (1kohm) have problem, the phone don't poweron.
and if the phone power ic (D500) have a problem or lose connection with the power way(OnSWAn net); the phone cannot be power on too.

and other one way, you check the phone current when you press power key; that must be go to aboute 80 ma with lcd.
