1）If both the screen and ambient lights are not turning on

This typically indicates a power-related problem, such as:

• An unstable or insufficient power supply

• A loose or faulty power adapter connection

• The device not receiving enough current to boot properly

What to try:

1. Power off the machine completely.

2. Disconnect the power adapter from both the machine and the outlet.

3. Wait for 30 seconds.

4. Reconnect the power adapter securely and restart the machine.

If the machine still does not power on, the issue is likely related to the adapter or internal power module.
In this case, please contact [email protected] for assistance and further diagnostics.

2）If the ambient lights are on but the screen is not lighting up

This usually means the device is powered but the screen module itself is malfunctioning.
Common causes include:

• Liquid leakage from the dispensing tube entering the screen area

• Damage caused by improper clamping of the tube

• A failed or incomplete firmware update freezing the display

• Screen module hardware failure

What to do:

If the issue is isolated to the screen, the display module can be replaced.
