Home Theater Questions? Ask a Technician for Answers ASAP
Hi, I'm Nathan.Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review your details here.
So the flickering happens only on att, correct? Not on dvd or appletv?
If you bypass the denon, and connect the cable (or other) directly to the tv via hdmi, do you still get the flicker?
What is the model number of the tv?
Is your att box a new 4k model?
That may be part of the issue, this type of problem usually comes from a resolution mismatch, so going into the individual devices and setting them to be locked at 1080p will usually help.
If it doesn't, the next step is a microprocessor reset of the denon, which I can guide you through if needed. That is done with caution though because it erases all the settings and then you have to reconfigure all the denon speaker setup again
You're very welcome, and best of luck!
