If the video displayed on a TV connected to either the Transmitter or Receiver occasionally drops out to blank screen one possible cause is an unreliable HDMI cable or connection.
1. First find out which of the HDMI links is unreliable
A. Does the issue occur only on the TV connected to the Transmitter
If yes then its most likely that the HDMI connection between the Transmitter and TV that is the issue
B. Does this issue occur only on the TV connected to the Receiver
If yes then its most likely that the HDMI connection between the Rransmitter and TV that is the issue
C. Does the issue occur on both the TV connected to the Transmitter and Receiver.
If yes then its most likely that the HDMI connection between the HDMI source and Transmitter that is the issue
2. Once the Unreliable Link has been identified please try the following
A. Double check that all your HDMI cables are fully inserted into the all the devices, HDMI source, TVs and streamer units.
Some HDMI cables have a large shrouding around the connector that can prevent the HDMI cable from being fully inserted into a device. Check this is not the case.
B. Check the connectors on the all the devices and cables are clean and completely free of dirt and dust.
If some dust or dirt gets into the connector on the HDMI cable or on the device its possible that a marginal or unreliable connection is made
