Is this a Control4 Problem?
I had a home theater guy set up my system a few months ago, and he talked me into using Control4. I don't love it -- I find it slow and inelegant. But it lets me have all the components out of sight and I can live with it. When I watch Apple TV, Netflix, etc, everything is great. When I want to watch Comcast, however, a weird thing happens: At almost exactly 15 minutes and 30 seconds of watching, the TV screen (Samsung Q90R) goes completely black. The audio continues for a bit longer uninterrupted, but then that glitches out too. I can use the remote to "watch" "Comcast" again, and the picture and audio come back just fine (though I've missed 30 seconds or so of watching while it re-cycles or whatever). Once I've got the picture back, I can watch again for another 15:30 before it goes black again. Over and over. Almost exactly 15:30 every time. Changing the channel or volume don't seem to interrupt or restart the counter.
This happens EVERY time I use Comcast as the input, and NEVER happens with the Apple TV. The only wrinkle is that it ALMOST never happens when I'm playing games on the PS4, but every once in a while (maybe twice out of fifteen gaming sessions?), the screen will repeatedly go black on me -- though I haven't timed it when using the PS4, so I can't say whether it is the same 15:30 interval.
I've switched out the Comcast box for a different model, and this glitch happens on both, so I don't think it is that. It can't be the TV, right, since it does not happen with all inputs? The culprit has to be the Control4 system? The home theater guy is working on it, but seems stumped.
This is obviously extremely frustrating, and threatens to scuttle any hope of hosting the Superbowl party this year. Any thoughts / ideas / solutions would be incredible appreciated!
Thanks in advance!
