Yamaha receiver makes clicking noise when plugged in but won’t turn on

Hi all, my Yamaha rx a3020 went dead while I was changing a headshell on the turntable without turning the receiver off, my bad. Since, it’s been not turning on, but clicks when I plug it in to the outlet. This seems to suggest relays are activated but maybe there’s a short somewhere? I’m not electronically capable beyond checking on a fuse so hoping someone here knows what I should track down, thanks in advance
 
Sounds like it entered protect mode.

Unplugged every cable, including power. Leave for 30 min, then plug in just power and see if turns on (reset procedure).

This guy went to the next step and entered into self diagnostic mode (with all input/outputs disconnected)
