    For a test: Bypass the Denon and connect directly to the TV from the C61k on the TV with the problem. See if it goes away.

    My set is also a Sony—900F—though that doesn’t mean yours isn’t the problem. Going direct from the C61K to the Sony would eliminate or confirm the Denon as an issue.

    Edit: Oh, what Jimmie said.

    I'm using x110b, with the Sony x930E TV, and Sony STR-ZA1100ES UHD Receiver. I have the annoying black flashes on non 4k channels on DirecTV

    try direct HDMI connection between your UHD TV and C61K client for day or two

    I refuse to do that, go direct, and bypass my receiver. However... i'm pretty hopeful right now!!! I came home, and I had a message about new software for my Sony XBR65X930E TV. It evidently is to provide Dolby Vision enhancements. After installing the update, it appears that the problem has gone away! YAY!! I hope that I don't curse myself by posting this. But so far, no black flashes!!

    I believe the Dolby Vision firmware actually came out several months ago (Feb/Mar maybe) and my black flashes seemed to start around the time I got that update, unless this is a newer version. Either way, I will see if a new firmware version is available for my TV on the off chance it fixes this problem.

    Gee, you mean it may be something with Sony software on their tvs? Call me not surprised at all... I hope this solves all the issues for you all!

    If it does come back, you need to bypass the receiver for a few days to determine where the issue is. It’s impossible to help if you can’t narrow down what the least amount of devices are used and you still have an issue. Troubleshooting 101...

    Well today I had the worst dropouts I’ve seen in my entire one month of service! (well, almost one month). It lasted so long I had time to get the camera out and take a video, it probably started 20 to 30 seconds before this video starts. Haven’t seen anything like this before, and when it stopped all seemed well again.

    Definitely your TV FW cannot keep HDMI-HDCP communication up to DTV standards.
    Does your TV have apps running in background ?

    That's definitely some sort of HDMI/HDCP issue. If you have other HDMI cables try swapping them around, it could be a bad cable. It is really easy for them to go bad in undetectable ways due to the way they're made.

    It’s an older HD Vizio, not-smart, no apps to run.
    That’s going to make troubleshooting difficult ... but I’ll set my alarm. :sleeping:
    Could be, I think it’s the one Dish gave me with the Joey 4K this C61K replaced, it’s always worked well. I have lots of HDMI cables, I can swap it out. Though according to @P Smith I’ll have to wait a month for it to happen again. :)

    There was a new Sony firmware available for my TV (XBR65x930E) over the weekend (dated August 2018) which I applied on Sunday morning. The description really only mentioned Android security updates, but in one day of viewing I don't think we had a single black flash. I will obviously continue to monitor it, but this latest firmware seems to have made a significant improvement for me so far.
