Solution:
Inspect Display Connector Pins:
- Check for Bent Pins: Examine the pins on the display connector for any bends or damage. Bent pins can disrupt the signal between the display and the control unit.
- Straighten Pins if Necessary: If you find any bent pins, carefully straighten them using a small tool or tweezers. Ensure they are aligned properly.
Reconnect the Display:
- Secure Connection: Reattach the display to the connector, making sure it is fully and securely plugged in.
Check Motor/Controller Connector:
- Verify Connection: Ensure the connector between the motor and controller is fully inserted and secure.
