Clicking noise eh? Is inoisclick, click, click, click, ... noise If so check the electrolytic capacitors in the power supply of the Bitax.

Yeah, I guess my next step is to take off the fan and see if I can spot anything wrong with it. And it's a continuous clicking noise as long as it's plugged in. It was looking like it might have been coming from the fan because it was trying to spin up. But the screen and the Pi Zero are totally black and not powering up. (I think it's a pi zero that that screen is sitting on.) But honestly, I just woke up. I'm going to caffeinate first and see what I can see here in a few minutes.

^ Yup usually power issues. Switch mode power supplies when feedback is unstable (high load, poor regulation due to failed passives etc) will flap output power. Usually it's on the output/secondary side but cheapo import power supplies have been shipping with half wave rectification and shitty caps in my recent experience.

I think it may be the power brick instead of the PS circuitry on the bitaxe

So the power supply could be the issue? Fun.

Oh shit lol. This is where the power plugs in. That looks borked to me.

Yes. I've seen and fixed this click, ckick, click issue on all sorts of electronics. Back in the day it was worse due to something known as the capacitor plague.

If you thought the chip shortage was bad let me tell you about the capacitor plague

The very real

That'll do it. If the power supply output can't keep up, it may click on and off.

Could be yeah. Not sure what the cause is though. Usually I'd say bad connection, and I don't have experience with these to know how the power regulation circuit is designed. It's possible with dc-dc converters that low PSU voltage could cause over-current which could have caused the connector to melt like that. That is unless there is a component that let out the smoke right near that connector I cant see?

I don't see anything in particular that would indicate something let out smoke. This happened overnight so I don't really know exactly when it happened or why or how. Took off the heat sink and I don't see the sign of anything else burnt out either.

Do you think it could have just been a loose connection? How badly burnt are the connector pins? Id try another known working power supply after inspection. Maybe poke around with a multimeter

I was able to boot up the little board that's on the bitaxe and it's actually reading PSU error.

Note that those wall wart power supplies have a common failure mode where they output OK voltage but can't output sufficient amperage.

Yeah, I'm starting to wonder if it's the power supply. I think that's where the clicking is coming from.

Already have an RMA in the works.
