Ender 3 stopped working

Filament 3D Printer Technical Help Creality Ender 3 / 3 Pro / V2
1

I am Vanbiele - I’ve had my ender 3 for several years and it just stopped working. It has been upgraded with a BL touch and a 32 bit V4.2.7 Creality mother board. I’d been having clogging issues and just serviced my boden tube and replaced the nozzle and it just shut down. When I turn it on now only the power supply fan turns on and no screen or anything else. I checked out the mother board but I did not see any burn marks on it. Thanks for your help.

Welcome to the forum Vanbiele! I believe that board has a fuse in it, have you checked to see if it has blown? Another thing to check is if the wires connecting the power supply to the mainboard are disconnected somehow; I’d check both ends.
