1. Check the Power Supply
Power Cord and Socket
Verify that the resin 3D printer is plugged into a functional power outlet. Test the outlet by plugging in another device to confirm it is working.
Power Switch
Ensure the power switch on the printer is in the “ON” position.
Power Adapter
Inspect the power indicator light on the adapter.
Test the printer with a replacement power adapter that has identical specifications. If the printer boots normally with the new adapter, the original adapter is faulty. If the problem persists, it indicates an internal wiring fault or motherboard damage.
2. Examine the Hardware
Hardware Connection Check
Remove the back cover of the printer and inspect all cable and terminal connections on the motherboard and touch screen. Disconnect and firmly reconnect every cable to ensure proper contact and seating.
With the power on (only if safe to do so), observe whether the indicator lights on the motherboard illuminate normally and measure whether the input voltage is correct.
Diagnosis Based on Indicator Lights and Voltage
Measure the output voltage at the DC interface of the adapter and the line voltage between the power adapter output and the motherboard.
