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

[skykomish]

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

Possibly/probably(?) the amp is in protect. Download the service manual

See chapter on self diagnosis function, page 29 of the sm.
Invoke DIAG, ie, while pressing TONE/BALANCE and INFO buttons press the Power ON button then read the protection info,
eg, I PROTECT, DC PRT.nnn, note the full message

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)

I’ve tried unplugging and left unplugged over night and plugged in the next day, same clicking but no stand by light no red light like the video, would not turn on
