¶ Troubleshooting steps
¶ 1. Check if the power cord of the pad is loose (you can unplug it again and turn it on again)
¶ 2. Use a power adapter (12V/2A or 24V/1.2A) to connect to the pad
(1) If the pad still has a black screen at this time, you can contact the after-sales e-mail: service@flsund3d.com
(2) If the pad can be turned on normally, you can continue to check down the list
¶ 3. Lay the machine flat and check if the 8P cable (under the Y-axis) is loose, you can unplug the 8P cable again
If there is no problem with the 8P cable, turn on the machine and check if the power switch and power supply light will be on（pay attention to safety）.
If the power supply light is not on, it is the problem of power supply, contact after-sales service to deal with it
If the power light is on normally, you can check whether the motherboard light is on.
¶ 4. Disassemble the upper casing of the machine and check whether the motherboard light of the machine is on
After checking this step, please feedback all the checking results to the after-sales mailbox for processing
