Symptoms of Camera Malfunction

• The camera does not power on.
• The display does not show video from the affected camera.
• Only one of the cameras (front or rear) is working while the other remains inactive.

Common Causes

1. Incorrect power supply

   • Using a USB power cable instead of the main harness can cause insufficient voltage, leading to the camera—or even the main unit—not starting.

2. Improper installation
   

   • Cables are not connected according to the installation requirements. Please follow the official Install CHIGEE Display wiring guide

3. Hardware fault

   • Either the camera or the Chigee Display main unit may be defective.

Troubleshooting Method: Connector Swap Test

Since the front and rear cameras are identical in specification and can be interchanged, you can test to isolate the fault:

1. Swap the cameras

   • Insert the working camera into the connector port of the non-working camera.
   • Example: If the front camera (F) is working but the rear camera (B) is not, connect the front camera (F) to the rear (B) port.

2. Observe the results

   • If the originally working camera fails to work after the swap → The issue may lie in the main unit or the connector port → The Chigee Display may need replacement.
   • If the originally working camera still works in the new port → The non-working camera is likely defective → The camera itself needs replacement.
