Unfortunately this was very short lived. I have now gone through all the online checks with no change and have invested in new HDMI cables.
I am using a Sony Bravia 4K tv through an AV receiver.
- HDMI cable from receiver to V6 is hdcp complaint
- Reciver HDMI port is HDCP
- HDMI cable from receiver to TV is HDCP
- HDMI cable is connected to hdcp compliant port on TV
Therefore no broken link in the hdcp chain that could have caused an issue.
Anybody have any further suggestions ??
