Re: New Sierra 1s and a dead Yamaha AVR???
well, that's not good. Probably why it was gifted...
anyways, two last things to try (if possible), see if you can find the last firmware for it and reinstall. Maybe, just maybe, the firmware got corrupted. Secondly, make sure HDMI / CEC / whatever it's called is also off in your TV and source devices (if they have)
Otherwise, looks like you need to buy a new AVR unless you have an older one you can use.
quick google search

Hopefully, it's not the third bullet if no test tones....
Re: New Sierra 1s and a dead Yamaha AVR???
one more thing -- try the tuner (FM/AM) again but in pure direct mode. If you get sound, it is likely an HDMI board and probably not worth fixing as I believe the 720 is several years old.

Yeah - I'll be replacing it.
