Here is my dilemma.. I have recently purchased a Panasonic VIERA TH-65DX740U and have it hooked up with my Denon AVR-789 receiver via HDMI as the pass through function worked well on my previous TV (Samsung - 1080p TV).

The issue I am having is that while watching anything through the HDMI cable (PS3, media player etc) every 10 minutes give or take, the screen will lose picture for a split second and go black, but no loss of sound. Netflix etc played through the built in Apps works fine.

Would anyone here know what the cause could be?

Could it be because its going via the Denon?

Just thought I'd ask you knowledgeable people here first.

Hi could be as simple as cable not seating correctly to HDMI handshake issues to cable issues.

If you can see the fault consistently then it shouldn't be too hard to diagnose. Try direct connections to the TV without the receiver, different inputs on the TV, different inputs on the receiver, different cable. If it does it on all devices and all connections then it's almost certainly the TV - maybe look at the mode settings on the HDMI ports?

Do you have anything else connected to the TV as well? Ground loop caused this for my kitchen TV, pulled the antenna out and it stopped doing it.

I actually wondered if it could be the aerial cable interfering as it is touching the HDMI cable along the line..

Also I will try the other suggestions if the aerial cable isn't the cause.

Are the ports on the TV HDCP 2.2 compliant?
If so, try to not use them as the handshake takes place 100 times per second, not 50 times like the older versions of HDCP.

Two of the four HDMI ports are TV HDCP 2.2 compliant, so I used one of the other two and also rearanged the aerial cable and refreshed the HDMI handshake and so far so good.

I think we'll see issues for some uses where the end users only options will be HDCP2.2 ports...
Fingers crossed that this works for you.
