[QUOTE="1am7h30n3, post: 1131790, member: 13860"] Some basic troubleshooting would be if the display/lights/etc. come on but you're not getting sound, then the problem is likely not with the power supply. If the display is showing something like protection mode, you could try removing unplugging the speakers from the amp, which would show if the fault is inside the amp or outside. If the display is working and no protection mode then as pieter said above try headphones or speaker AB selection to try and see where the fault is. Sometimes the relays which turn the channels on/off go bad on AVRs, but if e.g. ALL speakers stopped working at the same time it's less likely to be that, typically one relay will go intermittently bad first and you'll have sound dropping in and out or not always turning on, etc. [/QUOTE]
