Common Sony XAV-AX100 Issues and Their Solutions
While the XAV-AX100 is known for its reliability, certain issues can arise over time. We'll cover some of the most common problems and provide solutions to tackle them head-on.
1. No Power or Blank Screen
This is often the first sign of trouble. A blank screen or the complete absence of power can be caused by several factors:
- Fused Circuit Breaker: The XAV-AX100 uses a fuse to protect its circuitry. If the fuse blows, it will interrupt the power supply.
- Faulty Wiring: Loose or damaged wiring connections can disrupt the power flow to the stereo.
- Defective Power Supply: The internal power supply unit could malfunction, preventing the unit from powering on.
Troubleshooting Steps:
- Check the Fuse: Locate the fuse box in your car, usually found under the dashboard or in the engine compartment. Consult your car's manual to find the specific fuse for the XAV-AX100. Ensure the fuse is intact. If it's blown, replace it with a fuse of the same amperage rating.
- Inspect the Wiring: Disconnect the XAV-AX100's wiring harness and visually inspect the connections for any signs of damage or loose wires. Secure any loose wires and make sure all connections are tight.
- Test the Power Supply: This step requires a bit more expertise. You can test the power supply unit using a multimeter. If it fails to output the required voltage, the unit needs to be replaced.
2. Audio Problems
Audio issues can range from static and distortion to complete silence. Here are the most common culprits:
- Speaker Connections: Loose or faulty speaker connections can cause audio problems.

- Software Glitch: Sometimes a software glitch in the XAV-AX100 can cause audio problems.
Troubleshooting Steps:
- Check the Speaker Connections: Disconnect and reconnect the speaker wires to ensure secure connections. Inspect the wires for any signs of damage.
- Test the Speakers: If you suspect a speaker issue, test them individually using a known working audio source. Replace any damaged speakers.
- Adjust Audio Settings: Check the volume level and equalizer settings. Try resetting the audio settings to factory defaults.
- Update Software: Visit the Sony website and check for any software updates available for your XAV-AX100. Updating the software can often fix audio glitches.
