My Yamaha receiver HTR 5730 was lying dormant (and unplugged)

pressing the standby/on button makes the receiver do a
clicking/ticking sound and it does not turn on.

I tried searching for this phenomena, but couldnt find any help
online. Can anyone suggest something?

Disconnect the speakers. If the clicking continues, the receiver
needs repair. If the clicking stops. Check for short circuits in
the speaker wire -- bare wire should not be able to touch ANYTHING
except the proper speaker wire terminal.

Unfortunately, the 5730 was a lower-end Yamaha, in the 129.00 retail
price class, several years old now and not worth a serious repair
effort, except if saving it from the landfill is important to you.

Actually, we want to keep leaded electronics out of ther trash.

Pretty close to what I had said, I believe. Anyway, according to the service
manual, the 5730 is mostly lead-free. One side of one circuit board (the DSP
board component side) does contain lead however. Then there are all those
capacitors. God knows what's inside those... Sanyo, Nichicon and the others
have gone to more eco-friendly formulations, but this was not the case when
the 5730 was made.
The HTR-5730 was still a decent receiver, even given it's size and ratings.
Doesn't sound like all that straightforward a problem, though. We're headed
toward the microprocessor possibly being bad. Yamaha has had a problem
sometimes with the power relay itself, also the memory backup cap used on
some models has been known to leak and cause unusual symptoms.
