I have an Ender CR-10 which I recently installed a clone of a BLTouch on. It all worked fine and printed well but once when I started the printer all the pixels on the LCD were white. Then when I started the 4th time the LCD just went all black and I got no power to it. I also have a Raspberry Pi 4B which I tried connecting to the printer but it couldn't anymore.
Do I need to get a new motherboard or is there anything I can do to see where the error is so I can fix it?
I havent measured any voltage yet, I'll have to do that when I have some spare time...
