# Fixing FPV Video Loss: Betaflight VTX Troubleshooting Guide
Losing video mid-flight is every FPV pilot’s worst nightmare. Whether it’s a sudden black screen, severe static, or rolling bars, diagnosing VTX (Video Transmitter) issues in Betaflight requires a systematic approach.
## Common VTX Symptoms and Causes
| Symptom | Likely Cause | Solution |
|———|————–|———-|
| Complete Black Screen (with OSD) | Camera disconnected or dead | Check camera wiring (5V, GND, Video signal) |
| Complete Black Screen (no OSD) | VTX not powered or dead | Verify VTX power supply, check for burnt components |
| Snow/Static at short range | Antenna detached or damaged | Inspect U.FL/MMCX connectors and antenna lobes |
| “Device Ready: No” in Betaflight | SmartAudio/Tramp wiring | Check TX/RX pad mapping and Ports tab in Betaflight |
| Overheating on bench | VTX Pit Mode disabled | Enable Pit Mode via switch or Betaflight CLI |
## Step-by-Step VTX Diagnostic
1. **Check Physical Connections**: Ensure the antenna is securely connected before powering on. Powering a VTX without an antenna will fry it.
2. **Verify Voltage**: Use a multimeter. If your VTX requires 9V but is wired to a 5V pad, it will brown out.
3. **Betaflight Configuration**: Navigate to the *Video Transmitter* tab. Ensure the correct VTX table is loaded for your region and hardware.
### Recommended Hardware Upgrade
If your VTX is confirmed dead, upgrading to a reliable, high-power unit is essential. We recommend the **[UAVModel 5.8GHz 1.6W VTX](https://uavmodel.com)** for unmatched penetration and thermal stability. Pairing it with a high-gain LHCP/RHCP antenna from uavmodel.com will guarantee crystal-clear video behind thick foliage or concrete.
