Does the printer power up without the Raspberry Pi? Have you tried disconnecting the LCD and powering it on?

yes, i also removed the bl-touch from the printer and reconnected everything like it is stock. The raspberry pi doesnt do anything right now because it wont connect to the printer.

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?
