5. Řešení problémů
If you experience issues with your rear view camera after installing the rectifier, consider the following troubleshooting steps:
- Žádný obraz nebo černá obrazovka:
- Verify that all input and output wires are correctly connected according to the wiring diagram (Image 2, Image 3).
- Ensure the reversing light is receiving power when reverse gear is engaged.
- Check the camera's power connection to the rectifier's output.
- Flickering or Unstable Image:
- Confirm that the rectifier's input wires are securely connected to the reversing light's positive and negative poles. Loose connections can cause instability.
- Ensure the camera's power and ground connections from the rectifier are solid.
- In some cases, interference can still occur if the vehicle's electrical system has significant noise. While the rectifier is designed to mitigate this, extreme cases might require further electrical system diagnosis.
- Nesprávná polarita: Double-check that the positive and negative wires are connected to their respective poles. Incorrect polarity can prevent the device from functioning.
- Poškození zařízení: Inspect the rectifier for any visible signs of damage. If damage is present, the unit may need replacement.
