I have the same issue. I have tried several remotes and nothing works. I have changed batteries, reset the tv, powered it off and back on....nothing. Then I went to the settings on the tv and tried to add a new remote, and it tells me to look for the pairing button...the same pairing button that the remote does not have on a Roku TCL TV. I am very agitated at this point.
I'm also having this problem. I have multiple roku TVs and one of them just stopped responding to any remote when before it would respond to all of them.
It's almost as if the IR sensor just stopped working. The remotes definitely still work on the other roku TVs I have so it's not the remotes.
I was using my phone as the remote through the roku app but I had to change my internet and now can't connect that roku to my wifi to connect it to my app.
Seems like a hardware problem with the tv
Beware. I've bought about 5 different remotes, even remotes Roku representatives told me to buy. I called again about 6 months ago and they told me to buy ANOTHER remote so I ended up giving up and buying a new TV. It wasn't worth the aggravation.
I found out the problem is the IR sensor ON the tv itself. You can buy an inexpensive replacement board and replace it yourself. I did that and the remote worked again, but now it won't connect to the internet, but at least now I have a 55 inch computer monitor. Great for doing PowerPoints for work!
