Black screen does not turn on

Check whether the ship-shaped switch under the back of the machine has hit the "position" and whether the red light of the ship-shaped switch is on.

If it doesn't light up, please check the power supply at the machine power fetch.

If the machine switch is pressed and twisted, it will turn on the black screen and touch the screen to see if the machine is in an energy-saving state.
