Has anyone had an issue with Yamaha's protection circuitry activating?
I've got a three-year-old TRS-7790BL that for a while has been turning off and on randomly. I always assumed it was just a minor quirk -- maybe related to a malfunctioning universal remote -- until just recently when I got the dreaded blinking red light indicating the protection circuitry had activated. Thankfully, I was able to reset the system by holding down the Info and Tone Control buttons and then pushing Main Zone. I initially thought a loose speaker wire connection was probably the culprit, but it happened again last night after I'd tightened all of them.
Any ideas of a possible cause? Could a failing HDMI cable trip the protection circuitry?
(I should note that I'm using the receiver with a Sony XBR 900E, which has had some issues since the last Android TV update. In what is apparently a known issue, the sound doesn't work when I first turn on the TV. I have to turn the system off and on again to get it to work. That got me thinking that the protection circuitry problem could be ARC related but that's just a guess.)
