Is anybody can tell me what's led603 mean ?

601 - machine power at all

602 - logic board is receiving power

604 - display communicating with logic board

603 - ???

I have problem with 24" iMac - he's start, but without any sound

on usb ports - no power

display is black of course

led 601,602,604 is lighting but 603 isn't

logic board or power supply (i guess) ?
