Standby or red color LED means either:

1) CPU IC got 5 volt but cannot send out the "On" signal due to the ic itself have problem or the eeprom ic have corrupted.

2) CPU IC could send out "On" signal but it cannot reach the main power supply section due to bad components in the optoisolator ic and surrounding components problem

3) On signal can reach the main power supply but main power supply itself have bad components like shorted secondary diodes, bad power ic and etc.
