Hello, Hoping to find someone with a similar problem (or ideally, a solution). I have a Tivo Bolt and a Samsung JS8500 4K TV. If I use an Xbox, Wii U, or Blu ray player with the TV... everything is fine. The Tivo Bolt is even fine, as long as it's not live TV. Recorded shows, netflix, amazon - even watching from the buffer - all ok. But the second I start watching live TV - every few minutes, a 1 second black screen appears. Totally random. Sometimes a few in 20 minutes. Sometimes none. I've swapped the HDMI cord that goes from Tivo to the TV. I've reset both the Tivo and the TV. Video output is 4K 60fps automatic. I've checked the signal strength meter but when the black-out occurs, I lose the meter so I don't see what's happening. Tivo retains the peak but not the valley - so you need to be watching the meter. I've swapped in an older TV (1080i max) and the issue isn't present. Wondering if it's something to do with 4K video output or my cablecard at this point. Any ideas?
