FAQ Why, starting the machine for the first time, the top light is on but the display screen is not on?

Official text: please contact your seller and never try to disassemble and repair the machine yourself at any time.
The seller gives the solution:
Remove the two screws on the side of the display screen, take out the display assembly, and plug and pull out the display panel cable again; if it is invalid, replace the display screen assembly.
