Video keeps going black

My Roku Ultra video keeps going black periodically. I've had it happen once every hour-ish to happening multiple times in 15 seconds. When this happens the audio keeps going. Not sure how long it's been happening but it's been at least 6 months. 

Anyone else have this issue?

Re: Video keeps going black

First suggestion is to try a different HDMI cable. Also try a different input on the TV, assuming you have more than one.

Same here, when the screen "comes back" there is a gray bar across top displaying the resolution. On all my Rokus using multiple networks and different televisions. It is definitely the Roku devices.

Six different Roku devices, six different televisions, six different HDMI cables, all do the same thing. Pretty certain it's the Rokus that have the issue. Also, several of the Rokus have been in use for more than one or two years with no issues, all now started doing it a few months ago at the same time.

When you say "six different HDMI" cables do you mean "six individual cables that are the exact same brand and model" or "six individual HDMI cables that are of different brands and models". You may be using junky HDMI cables across the board. I'm not saying you need $30 (or more) cables, but maybe try various different cables, and make they're made for 4K.
Yeah, I got some Rokus.

Re: Video keeps going black

I use Amazon Basics HDMI cables, and they are very inexpensive. Worked great on my Ultra and 4K TV, and still working fine with my Shield on the same TV. The Ultra is now on an old plasma set with an 8 year old cable, also still no issue. But they can be highly sensitive to the cable quality.

Re: Video keeps going black

I have the same issue with the 4k streaming stick + (which btw has no cables). I have it powered with the included power brick connected to mains power. This is my third generation of Roku, where with all previous generations I never had a "nagging" issue like this. Given my wife is not happy with this "new problem", I likely will buy a different brand altogether and replace my brand new Roku 4k stream stick +.

Re: Video keeps going black

My Roku started going black 2 days ago.  This is my first experience with Roku and I've only had it since 1/01/20. I have a Premiere device.  This sounds like a manufacturing problem.

Re: Video keeps going black

After calling Customer Service and moving the HDMI to a different port on my TV, the blackouts stopped.  It's only been a couple days, but so far so good.
