CR-10 Creality

I've been away from home for 8 months, printer was doing fine before I left. I can't do anything anymore with the printer as of now. I'm running Marlin with a BLTouch sensor.Basically what happens when I try to do anything the screen goes blank and nothing happens. Or the printer restarts with the screen displaying:
Homing failed:
PRINTER halted
Please Reset

The only thing that happened is the printer has been moved to a different location in the room. Would this be a motherboard issue? I do have a RAMPS v1.3 lying around which I can use but I don't know if it's better to get the SK3 Mini E3 or something

Maybe to start hook up the printer to a PC/Laptop via USB and use pronterface (https://www.pronterface.com) to send an M119 command. If you encounter problems finding the printer in pronterface where it does not connect, try this driver: https://www.th3dstudio.com/hc/downloads/drivers/ch340-drivers-th3d-uno-creality-v1-1-x-v4-2-x-board/

Then manually trigger the endstops and resend the command to see if they work properly. If not, check all your wiring for any potentially loose connections. If that works, try sending a G29 command via pronterface and see what the response from the printer is. Observe what it's doing and check for any reports via the command interface inside pronterface. If that works, check the values for the bed mesh that the printer will report. Do a G28 followed by a G29 2/3 times and check if the values are more or less constant. If yes, good. If not, you might have problems with electromagnetic interferences which you can read more about here: https://marlinfw.org/docs/hardware/endstops.html#endstops-and-electromagnetic-interference-(emi)

I feel stupid, I forgot there was a power button at the back of the 3D printer.... Now it's working fine

Wait what lol? :D Well if you encounter any other problems, hit me up here or on my discord server: https://discord.gg/vGXgTV8xvZ
