Grateful for any advice and assistance you're able to offer. I have a Denon AVR 2113 running input from the following sources - SKY Q Denon DBT-1713UD (Blu Ray) Amazon Fire Camera DVR (iwatch) The Sky Q (and the Blu Ray) used to constantly flicker on the screen or would loose connection for a split second (the window in the top corner of the screen 'HDMI1' would come up) or the screen would go blank (no signal displayed on screen) but the sound would continue to play. It has now pretty much stopped playing Sky Q (and Blu Ray) altogether. Amazon Fire & Camer DVR continue to show just fine on the screen. I have tried connecting the HDMI directly between Sky Q and the screen (samsung LED) and it works just fine. Interestingly the Blu Ray plays sound but not video when connected directly to the screen. Any thoughts or experience on this would be very much appreciated. Guessing it is an AVR problem as Sky Q works on the same HDMI cable direct to screen but confused by the Blu Ray lacking video. Many Thanks in advance.
