What should I do if the machine has a black screen, no light, no sound, and no light on?


solution:


(1) Check whether the 220V voltage is normal. Whether the connecting terminals of the power cord from the machine and the external power cord are connected correctly, confirm that the machine is powered on.


(2) The power indicator of the machine does not light up to prove that the machine is not powered on.
