Hi, my Roku 2 suddenly stopped working properly. It is connected to a Samsung TV for about 2 years now and worked perfectly well until recently. Suddenly, the connection was lost and the TV changed from the Roku to the aerial and started automatically scanning all aerial channels constantly and on a loop. The TV could no longer read Roku. I tried to change the Source to go back to the Roku. This worked once but then went back to the areal source and started scanning non stop. I can no longer even select the Source, the constant scanning won’t stop and won’t let me do it. I connected the Roku 2 to another TV, also Samsung which until I connected it to Roku 2 worked perfectly. It worked to begin with but then within a few minutes I had exactly the same problems. Both my TVs are no longer working with or without the Roku. Please help!
New Roku does not work either ☹️ we have retuned the TV and it works fine without the Roku.
When we connect the Roku, it works for a couple of minutes or so and then loses the connection completely and starts going through the channel list on a loop.
This is truly weird. There's something else going on that we're missing.
Roku 2, depending on the model, is either around 8 years old, or 6 years old. That's a long time in streaming device years. If it's the model 2720, I'd suggest replacing it. If it's a model 4210, it's actually a Roku 3 on the inside, but still getting on in age.
It would be helpful to know which Roku 2 model you have, as they are very different devices.
Since you did replace the Roku, and the issue continues, that points away from Roku as the issue. What Roku did you get recently? Model number is very helpful.
Also, are you using the same HDMI cables to connect the Roku devices? If it's the HDMI cable that causing issues, then changing TVs or Roku devices might not resolve anything, if the bad part is still in the mix.
Let us know which Roku model numbers we're talking about and let's see if we can figure this out.

A few days ago I bought a new HDMI cable in case there was something wrong with it. Did not work either.
I do think that the Samsung TVs and Roku boxes stopped communicating with each other (there must be a technical term for this). The Rokus won’t work on any of my Samsung TVs. The TVs work ok otherwise.
The Rokus are connected on the WiFi ok. I have fibreoptic connection with is very good. I am now thinking of buying a new TV. I will contact Samsung though to see if other customers had similar issues.
