Hi, I’m a newbie to 3d printing. I was using the printer and it was working just fine, I inserted the SD card to print something and the screen spewed out a bunch of gibberish. So I thought to turn off the machine and reboot it. When I went to turn it off the power switch wasn’t clicking off, I futzed with it a little and the machine turned off. Then I couldn’t get it to turn back on. I thought maybe it was a bad switch so I pulled the switch out and now the switch seems to be working fine but no power, the fuse seems to be good also soooo… Any ideas? BTW there was no smell of electronics burning or smoke etc…
You inserted your card, it may have bent a pin inside the reader and shorted something out. You can try to disconnect one ribbon cable at a time from the card reader and power up to see if it comes back. As well, inspect the slot for bent pins.
