I have a Samsung TV, but I've never tried its apps, but problems with The Roku Channel on Roku devices can be caused by using a VPN or ad/content blocker. Not being in a supported region can also be a problem. Do any of those apply?
Thanks for the reply.
No VPN in use or content blocking on that connection at all. I can use the same connection with a desktop computer and the Roku web app works OK.
This is from a USA location.
Also, I forgot to mention I have tried both logged in with my account and not logged in at all to make sure it wasn't some sort of account problem.
LouF, the only other thing I could suggest to try is to reboot all of your network equipment - gateway/modem/router. I would also reboot/restart the TV since that's a common "fix" for Roku devices. I don't know if the TV's have a "restart" option, so if not, just unplug the power for several seconds. Don't simply turn it off and on. After that, I'm out of ideas.
I may be having the same problem discussed in this thread although it looks like my TV is much newer than the ones listed there:
