Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
Unfortunately this is a very common problem with these receivers, and a known flaw.
While it can sometimes be caused by corrupted firmware, it is almost always the result of an underlying hardware relating to a defective processor chip.
As a 2011 model receiver, it is at/past its service life at this point, so seeing hardware failures start to develop is not surprising.
The one thing you can attempt here is a microprocessor reset to refresh the firmware/operating system.
Unplug power to the receiver for 5 minutes.
press and hold the ENTER button on the front panel
keep holding while powering on.
If it comes up on screen with a RESET? button, use the preset <> buttons to navigate to select reset, enter
then enter once more to confirm.
Power off and back on.
If no change (error message persists) then it would confirm a hardware fault, which would require repairs to correct.
At that point, you are better off buying a new receiver, as repairs will run you about $400 on average, which would be better spent on a new model with updated features and a fresh warranty.
Should it come to that, I can help with finding a repair shop or recommending replacement models, if you'd like.
