VIDEO CUTS OUT COMPLETELY AFTER A FEW HOURS OF USE
- Some source devices (Set Top Boxes, etc.) have power-saving features that can turn off or de-
sync the HDMI connection after hours of inactivity. Check power settings on the source device
and turn off any power-saving modes. (This will vary from device to device.)
- Check resolution settings on the source. Recommended setting is 1080p FIXED or 720p FIXED. If
the source is a computer, set Display to “Extended mode” or “Extend these displays” and set to
1920x1080 or 1280x720.
- On the unit, go to Advanced > Fixed EDID setting, and change from Auto to match the fixed
resolution setting on the source. For instance, if the source is set to 1080p Fixed, change Fixed
EDID to 1080p.
UNIT DOESN’T WORK WITH VIDEO SWITCHERS OR MIXERS
- Ensure the Video Switcher supports EDID. EDID support is required for our modulators to
understand the signal from HDMI source.
NO AUDIO OR POOR AUDIO (VIDEO IS WORKING)
- Check HDMI Audio Out settings on the source device. Set to Stereo PCM Linear or Dolby Digital
2 Channel (Uncompressed).
- Check other audio settings on the source device to confirm audio is not turned off or muted.
- Check HDMI cable connection between source and unit. Disconnect HDMI source and
reconnect it to establish a new HDMI handshake. Test with a different cable if possible.
- Test with a different source (e.g. DVD player) if possible.
AUDIO IS NOT IN SYNC WITH VIDEO
- This may occur if the audio output goes separately to a sound system before the video goes
through the unit. You can purchase an audio delayer to sync the audio before it goes into your
sound system or take the audio feed directly from the output of a TV tuned to the channel.
- To fix, adjust the Audio Delay settings on the affected TV. (This varies from TV to TV, see your
TV documentation for more info.)
UNIT WON’T POWER ON
- Check the connection between the power supply and the unit. The cable screws securely into
the DC jack on the side of the unit.
- Check the connector, cable, and power supply to make sure there is no damage.
- Check that you are using the original power supply for your model.
- Test using a different power supply for this model, if one is available.
- Test with a different known working outlet.
- Ensure that all the nuts on the connector are secure and not loose.
