I have an older tcl Roku tv at my home in another country. It’s always worked fine, but now the simple remote that came with it is not working. It won’t communicate with the TcL in any way. Two brand new Duracell AAA batteries properly installed. I’ve tried the “home button/back arrow” 5 - 10 second press repeatedly, no help. I reset the tv entirely, thinking that might help, but now I’m just stuck on the welcome, pick a language and get started page. The console buttons are so elementary that there is no apparent way to run the set up or set itself manually. What recourse do I have? I have a streaming Roku device that works, but of course it did not work when connected to the hdmi outlets on this set. If I purchase a new remote, what’s the likelihood it’ll work? I have to travel 9 hours to this country to get here. Any suggestions?
