No standby light...! 5V and 3.3 V are OK from power board. 5V pin 2 of P811A 3.3V pin 9 of P810A Eprom is a 25DF321

The problem may be in the secondary power supply. 3V3 and 5V Standby supply is working fine, but the secondary power supply does not work. Check the circuitry of this to see if there are any damaged component.
