I've had it
Today I get home and for giggles turn it on, and it comes on! I fiddle with some settings but then notice that when I turn the volume up there is no sound. Turned it back off and was going to unplug and replug the front and center speakers back in (all banana plug). Turned it back on and 3 seconds later powered itself of again!
Back to square one! I think it's time for another receiver!
