Re: Harman Kardon AVR 270
Are you sure about those pin numbers? Pin 1 is the 5 volt supply voltage, Pin 2 is ground, pin 3 is the output
But heating never did turn on the fans? It does seem odd that neither fans runs, FAN1_ON and FAN2_ON commands come from ic2103 and should output around 3v to D980 & D970 Fan1 (heatsink) also needs audio at the speakers to turn on the heatsink fan.
Have you tried a processor reset (page49)
