About a week ago my RX-V765 started to shut down about 5 seconds after pressing the power button. I checked the speaker wires for shorts and checked the speaker impedance setting per the manual. Also, I have tried disconnecting all the speaker, HDMI, other cables -- same result. After three attempts the receiver will not turn on at all until the receiver is unplugged from the outlet and plugged back in. The same problem still occurs.
When it first started happening, after a few attempts it would stay on. Once it stayed on everything worked fine and it would not shut down even after leaving on for a day. There were never any messages on the display to check something. As week went on, it took more attempts to get it to stay powered on. Now, it will not stay on no matter how many times you try to press the power button.
I have had this receiver less then a year and am surprised this is happening with a Yamaha product.
Has anyone had this problem and if so what was the fix?
