    While watching either live tv or recorded tv everything looks good then out of the blue the screen will go black and the sound will cut out for about a second. Then the picture and sound will come back. This continues for how ever long I'm watching TV.

    Tivo Edge Cable
    Samsung UN43MU6300 (Software: T-KTMAKUC-1270.3, BT-S)
    Verizon FIOS (Motorola CableCard)

    Any one else experiencing this issue? Any Ideas what I can check?

    Thanks

    I get the black screen/no-audio for almost two seconds, but this is usually associated with a remote control button press - Info, Top-Right-Arrow, TiVo, Advance, Replay, etc. It happens often, meaning, many times in an evening.

    Mine is only when viewing. No button pushing.

    Does it happen at the start or end of commercials or something like that? Sounds like maybe your TV is changing resolutions. I would think a channel would be the same resolution all the time and mine have never changed, but I have no idea if that is universal.

    It's random, most of the time during the show and not around commercials. I'll check the settings again on the TV when I get home tonight.

    Possibly not it, but you could try making sure your video settings are not on the "Auto" setting. Pick the resolutions your TV can handle.

    I recorded an instance of screen blanking. The exact moment of blanking happened a tiny fraction of a second into a commercial with DD2.0 audio (as reported by preamp) after leaving the previous commercial with DD5.1 audio (as reported by preamp).

    deadbob's issue doesn't make sense so I'd suspect the Tivo and try on another TV. Is it repeatable? Happens at the same time if replayed?

    I think ovittocs' issue could be anything in the chain that might be switching. You mention it blanking when switching audio. Check your Tivo's audio settings and maybe try skipping any AV equipment and see what happens if you go straight to the TV?

    I'm not a specialist in any of these components, but I do have a ton of troubleshooting experience on a bunch of random hardware. These are just the steps I'd try to narrow it down. Hopefully something helps and someone else can step in with an answer when we gather enough info. Or you'll have some answers if you talk to Tivo support.

    Yep, I agree with rbronco21. Could be something else in the chain, however, the blank is recorded and still shows in slow motion. In other words, once it shows up, it's recorded and can't be undone.

    Currently the EDGE is going through prepro then out to an old plasma (1080P) I brought out for the last week while I transition from projection to new Sony 85" panel. After the new panel is up I'll test all 3 screens for any variation in operation. Tabulating new occurrences with the other screens connected the same as now, or connecting EDGE directly to each screen, or not if no future blanks are seen, will be interesting to discover.

    Well, I went through and double checked everything and the settings were correct. The one thing I didn't think would be the problem was the HDMI cable. Swapped it for a HDMI 2.1 cable and the issue has gone away.

    Thanks for the all ideas.

    Pleasanton,...
    Please make sure you are using a "high speed" HDMI cable. It needs to be rated for 18 Gbps or you may see drop outs or HDCP errors due to low signal strength at the TV if you're running at 4K with HDR turned on. The HDMI cable that comes with Edge is a certified, high-speed cable. You can try turning HDR off in settings or lowering the resolution to see if your cable might be causing an issue.

    I have seen the black screen too. It seems to happen when a recording starts maybe when one ends and the next starts. I am also using the cable provided in the box.

    Thanks for the word and education, Ted. After years of "Monster hype" on HDMI cables, I've become a bit immune to it all and have never really understood that there can be a difference between cable types (apart from the hype).

    Ultra HD High Speed HDMI cable is on the market now. The specs are 8K 48 Gbps speed also known as hdmi 2.1. However a lot of them are not certified yet and they are a little pricey. Also lengths over 6 ft are hard to come by.

    When they come down to earth I will be upgrading to them even though I have 4k.

    Or just go to monoprice for all your cable needs! I swear I need a cable shipped every couple months. I do colors so I know all my orange cables are the latest spec. If I need newer ones for 16K, 4D, or Smellovision, I'll get another color.

    Wow, that's crazy. Guess I didn't look at the latest ones. I just got a few older 10ft skinny ones to route through a cable cover for cheap.

    I have this same problem with new Edge Cable, Onkyo TX-NR616 receiver. Although I think the black video is less than a second (and audio continues). Happens with recordings, live cable and streaming (Tivo+). I've tried two cables (Tivo 4K cable in the box and the old Monster cable that worked fine with my Roamio), and Tivo just RMA'd the Edge. Same problem. Any other ideas? I'm really frustrated.
