    I am glad I found this thread. I am having the exact same issue. When watching TV through my Tivo Bolt Vox, I will intermittently get video and audio drops for anywhere from a second or two to several seconds at least. This happens as far as I can tell randomly. I have a rather involved set up, a few sources all running through a Marantz AVR, and then from the Marantz to the TV I have HDMI to Atlona extender and back again because the distance between the Marantz and TV is too great for just HDMI. All the other sources seem to be working fine, but the Tivo has these drop outs. I thought it was the Atlona extender, but after reading this I am thinking it is with the Tivo source only. Perhaps my first step is to upgrade the HDMI cable from the Tivo to the Marantz and see if that helps. Thoughts? Also, what should I be setting my video output to on the Tivo. The TV and the Marantz accept 4k HDR.

    Update: I now no longer set the tivo to output "auto". My whole system is setup for 4K output and therefore auto will scale up to 4K and send it through my Marantz AVR, across my Atlona extenders and back in to my Samsung UHD TV. All other sources, except for the Tivo, work perfectly fine sending through the 4K signal. I am not sure why the video and audio is so undependable when the Tivo specifically does the scaling. So I set video output to everything except the 4K settings and now it works without the screen going dark at random times.

    I am having the same problem, every 2 minutes black screen for a few seconds and audio goes out. It is the same experience you would get when "changing" the channel. I have the output on auto, I tried changing to 1080i, 720p, 1080p etc nothing fixed it.

    It's not just the display that goes black but the live tv buffer gets deleted so I can't rewind live tv past the black out.

    Restarting the tivo fixes it for a few hours, but then it goes back to black screen every 2 minutes.

    It has been my experience with tivos that they are particularly finicky when it comes to handshake issues. That being said, there is one more change I would make to your Tivo settings. Uncheck, eliminate, the output setting of 1080p so that only 720p and 1080i are set. See if that fixes the issue. If that does work, then go back again, and try enabling the 4K Pass Through also, but only the 4K Pass through, not 4K upscaling. If it starts to go on and off again, uncheck the Pass Through. Let us know.

    The "Pass Through" options only apply to streaming video.

    Yes, but we do not know if he is using the apps or not. So I was suggesting it just in case he does use them.

    It's a Bolt. I'm surprised no question on ODT.

    "I'm surprised no question on ODT.": I am not sure what that means? What is ODT?

    While I have seen a lot of posts about various cooling methods and resulting reductions to ODT (including my own efforts), I can't say I have seen anything that actually links high internal temperatures to anything other than potential HD life issues. Anecdotally, my audio dropouts SEEM to have vanished after I cooled the Bolt down (hard to prove a negative) but has anyone found an actual demonstrable / repeatable effect?

    the problem fixes itself for a few hours when I restart the tivo, I don't think that would fix it if it was a heat issue.

    I HAVE THE SAME ISSUE IN TWO Premier's, one a 4, the other a 4XL. Both just go black, sometimes they come back on after a couple minutes, sometimes they are just gone. The only thing that brings them back to life is a reboot. I use IR's (USB powered) on both and find that disconnecting the IR's until the reboot is complete helps for while, but after a few hours the same thing happens.

    I am on SPECTRUM here in Tampa Florida, and they have been working on the issue for 5 Months. They tell me that all many of thier TIVO customers are having the same problem and they all started to have it about the same time , 5 Months ago. They have changed Tuning Adapters and Cable Cards 20+ times. The problem remains.

    I just bought a TIVO Bolt .... I received instructions that included a warning about finicky cable card hookups. They recommend getting 5 cards, will Spectrum charge me for all of those?

    Spectrum has been attentive to the problem but so far unable to solve it with my Premier 4's. I hope my new Bolt doesn't have the same issue.

    Cliffeck, without more info on your equipment and settings it is hard to tell. But the first thing to try is to go into your TiVo video settings and do not enable 4K upscaling in the the TiVo. Once you do that let us know the result. Let your TV do the upscaling. See if that fixes the problem before doing anything else. I'm not very technical, but I believe that the tivo's have a problem with their 4K upscaling when it comes to handshake issues.

    Premiere and Roamio boxes don't have 4k options. The Bolt does. Series 4 & 5:

    I have the same problem.
    The issue seemed to be related to a failing hard drive. If I deleted a bunch of content to take the used capacity down from 65% to 58% or lower then the cutting in and out was solved. As soon as I recorded enough programs to get back to the 63-68% range the cutting in and out began again. This would point to the fact that as the hard drive is filled up with programs then the TiVo is reading and writting to a different sector of the hard drive. That sector I suspect is starting to fail.
