Came back to a printer that won't turn on

Hi guys,
I have a HIC Prusa i3 3DP-12. This is my first time working with a 3d printer, and so far it's fun! After assembly, I printed 2 parts with no problem and was very pleased with the quality. However, the 3rd part was estimated to take 5 hours, so I started it and left it. I could have sworn I heard some clicking while I was gone, but it didn't register in my mind, and I honestly may have made it up. When I came back, the print was only half finished, and the printer was off, even though the power switch was still on. Now, no matter how many times I unplug/plug it and flip the switch, there is no response at all. One thing that was interesting was that afterwards, I was manually turning the screws for the Z-axis and the left one made a snapping sound before turning in my hand as it normally would. This is what reminded me of the clicking I thought I heard earlier. I'm not sure if a stepper motor blew out and fried something, or if my control board or power supply went dead. Any thoughts? Thanks in advance!

I think it's unlikely that a stepper failed... they're pretty robust. Wondering if the snapping sound was something stuck in the gears/belts/whatever?

I'd start by checking the power supply... Are you getting 12V? Then check that your controller board has 5V.

Its dead and should be buried in the garden.

Not really.

Just what frank said - basic fault finding starting from the fuse in the PSU plug following the flow inwards. Sniff for smells & look for damage.

Ok, finally got a voltmeter and poked a bit. Turns out, the signal stops right after the power switch on the control board! I'm hoping HIC will replace the switch. In the meantime, can I simply just bypass the switch and wire the power supply right into where the switch would connect?

I'd just put a jumper on the back of the switch, connecting the input to the output. I assume it's just a simple-pole switch?

Hey guys,
To update, after waiting for 4 weeks for a replacement switch (embedded in the cage) from HICTOP, I finally received it, installed it, and found that it completely solved the problem! Thanks for the help.
