7. Troubleshooting & Maintenance
1) If the POWER indicator doesn’t work or no respond to any operation:
The power adapter is not connected with alternating current power.
The power switch is not on.
2) When there is no output signal:
Check if the audio/video connector is broken (check with multimeter or oscilloscope).
Check if the audio/video connector is well connected.
Check if the source device/display device is powered on and turned on.
3) When the output image is blurred:
Check if the video cables are in bad connection.
Maybe the video cables are in bad quality.
4) If the static becomes stronger when connecting the audio or video connectors, it
probably due to bad grounding, please check the grounding and make sure it
connected well, otherwise it would damage the converter.
