I have 4 Roku's and three different models. I have issues with my screen cutting in and out periodically on the Ultra. I have replaced the HDMI cord 4 times and it fixes the issue for a short amount of time before the problem resumes. There is literally no one you can talk to for reimbursement or tech support. Very disappointing client experience for a faulty device.
My Ultra just started doing this too. It is about a year old and has been operating fine. No changes to configuration. It does seem to be associated with a recent software update rolled out by Roku, according to my observations, but I see that others have complained about this since last Spring. Some are saying that getting a Roku did not solve the problem. That is odd. What are we supposed to do if Roku company is not interested in this?
I'm surprised this is the answer. Blow it out? You did this with the original Nintendo. The HDMI cords do not get unplugged so how is dust going to get in the port? Try a new TV. How does trying it on a different TV supposed to Fix the problem. I
m having the same issues with both my ROKU. I think it is the last update that is causing issues. Both my TV's are under 2 years old and I purchased both Roku's with in the past 8 months.
Though skeptical, I did unplug my Roku Ultra for 30 seconds and while back there literally blew out the HDMI port and HDMI plug. Upon restart I was given the message "Your system has been reset to UHD (Ultra High Definition) .. I may have set my settings to the wrong definition along the way. I have a 4K QLED Samsung Smart TV. Display type was automatically reset to (auto detect), mine being 4K HDR (10) at 60 Hz, HDCP 2.2. Initially, this solved my picture cutting in and out problem. But Also, the next day, The Problem WAS and IS Back. Disappointed.
