What should I check if my microphone isn’t working?

First, verify your microphone has power or fresh batteries. Ensure the receiver and transmitter are on the same frequency. Check cables and gain levels on your mixer or console. If it’s still not working, ADMFA Audio can diagnose wireless interference or faulty hardware on-site.

Why is my LED wall or screen not displaying video?

Check that the signal cables are connected and the controller is powered. Sometimes a single failed panel or data cable can cause blank sections. If your LED modules, controllers, or power supplies are faulty, ADMFA Audio can repair or replace components quickly.

How do I fix sound distortion or static noise?

Distortion or static often means overdriven gain, poor grounding, or damaged cables. Lower channel gain, mute unused inputs, and inspect your cables. If the noise persists, our technicians can isolate the issue, rebalance your system, and eliminate feedback loops.

Can ADMFA Audio repair my AV system on-site?

Yes. ADMFA Audio provides mobile emergency AV repair across Houston and surrounding areas. We can service LED walls, sound systems, mixers, and wireless microphones directly at your venue or studio, usually within 90 minutes of your call.

Emergency AV Repair & Troubleshooting

When your sound system goes silent or your LED screen goes dark, every second matters. ADMFA Audio offers 24/7 emergency audiovisual repair services in Houston and surrounding areas. From LED walls to wireless microphones, our certified technicians are ready to bring your system back to life.

🔊 No Sound or Poor Audio Quality

Check that your audio mixer isn’t muted and that all cables are fully inserted. Inspect your speaker connections, power amps, and confirm the source signal is live. If the issue persists or there’s distortion, call ADMFA Audio for full signal path testing and rebalancing.

🎤 Microphones Not Connecting

Confirm your receivers are powered and on the same frequency as transmitters. Check for battery levels and ensure antennas are upright. Wireless interference or pairing issues are common — our team can re-scan and configure your system for interference-free performance.

💡 LED Wall or Screen Failure

If one panel or the entire wall goes dark, start by checking the signal chain: power supply, receiving card, and data cable continuity. Our technicians can diagnose failed modules, replace power supplies, or reprogram controllers within hours.

🎚️ Mixer or Controller Malfunction

Software glitches, bad faders, or firmware issues can freeze your console. Try a reboot and disconnect unnecessary peripherals. ADMFA Audio performs onsite firmware updates, repairs, and board replacements for Yamaha, Behringer, Allen & Heath, and more.

📡 Signal Dropouts or Static

Dropouts often stem from damaged cables, grounding issues, or poor RF management. We’ll perform cable tracing, shielding inspection, and interference isolation to eliminate unwanted noise and restore clean, consistent output.

🎥 Video Feed or Projection Issues

Black screens or flickering projection can point to HDMI/SDI connection loss or damaged splitters. Check video source power and refresh settings. If nothing restores signal, our video engineers can test line integrity and reconfigure your switchers and signal flow.
