HICTOP DIY Prusa I3 - Finished assembling but auto home does nothing

Hello;
You should check voltages and make sure that the 12 Volt Supply is supplying 12volts.
Then we need to make sure that the 12 volts is correctly connected to the controller card.

Do you have a multimeter?

Thanks ! I really appreciate the help.

ok so I assuming that a USB 5V is not enough to heat stuff.
So I need to troubleshoot the issue from the POWER SUPPLY.

I dont see any voltage coming out of the PSU to the main board....
And now I just opened up the PSU to see a blown fuse:

First, is this a blown fuse? And if so, can I replace? or do I just purchase a new PSU?
Also, could I have caused the fuse to break? I put it on 110v from 220v prior to plugging it.

I am worried that if its not just a faulty PSU, the fuse will blow when I buy a new one.

Looking at the Power Supply image the Fuse is blown.
Beside the fuse is a Black Thermal resister I may also be bad.

Do you know how to solder.

I dont have much experience in electronics. I am learning.
I have a soldering kit.

I found this, looks like its the right fuse.

I dont mind soldering to try to fix the issue.
But getting a 8$ fuse to fix a 35$ PSU...

Might be worth buying new PSU...

Might be but look at all the fun you will miss out on. Plus learning how to solder.
Before you spend the money as a temp test you can jump the fuse to see if the supply still works.
I would disconnect it from the Controller first, just in case.

I would use this fuse. and buy the way Fuses should be way less than $8 each

You could get the fuse at any appliance repair shop
