Hello, you can first check whether the cable is tightly tied.
Then connect the computer to the printer and see if you can control the printer through the computer to complete some basic operations, such as moving, heating, etc.
If it works, the screen needs to be replaced. If not, there is a problem with the motherboard. You can contact geeetech sales to replace the motherboard.
