So last night watching blu ray. My receiver just shut off. And then goes into standby mode. After unplugging the ac cord for several minutes. And plugging it back in. And powering it back on the power button isn't highlighted, but the light comes on for the knob and the display screen for a few second. Then goes back to standby mode.Their are no error message on the display. And trying the factory reset doesn't work. The main problem is I or my friend doesn't have the receipt. So I won't be able to use the warranty exchange. I have called harman already, but no solution for my problem. They said I can take it to an authorized dealer for repairs. But if somebody has an idea to help me. I would rather go that route and save me some money. If anyone has any idea please help me out. I've only had this receiver for a few months.
