I think my Onkyo is toast

[kmcorolla15]

I have an Onkyo TX-NR696 that as of today only puts out a faint signal to the subwoofer. Checked the crossovers, speaker setup, cabling - all appears correct. Hooked up another known good sub and another cable, same problem. Sub was working until recently. Ran auto calibration, same problem. I'm thinking bad board somewhere, but I'm still new to this. Am I just out of luck at this point, and if so, what would be a good receiver that I could buy on FB Marketplace or on the used market? It's just going in my home office so I don't need Atmos, etc....just eArc and 7.1. I mainly just use it for YouTube and music.

Thanks in advance!

So everything else is fine, just a low pre-out signal for sub? What sub trim settings have you tried? Trying a second sub is pointing at the avr, tho.

There's not many settings for the sub on this unit, just On/Off, level and LFE. They're all on. Everything else on the unit works fine though.

Ok, this is weird.....so after letting everything sit overnight, my wife powered on the system this morning and the subwoofer is working again. Wondering if maybe the receiver was overheating? It was a bit warm when I was working on it yesterday.
