## Troubleshooting
## Troubleshooting
**Question**: 没有检测到Signal
**Problem**: No signal detected
- Check antenna connection
- Verify frequency settings
- Adjust volume
**Question**: Image失真
**Problem**: Image distortion
- Lower input volume
- Check for noise
- Try different modes
**Question**: 同步丢失
**Problem**: Sync loss
- Adjust frequency accuracy
- Improve antenna direction
- Stay away from interference sources
