Ok I would need to know what steps you have tried. First are you unable to see all channels or just TVLand? If no channels are showing up, it is not a problem with the TV Land channel.
it is most likely the authentication setting or that you are not on the same network as discussed here - https://plexapp.zendesk.com/hc/en-us/articles/201375923-Why-are-none-or-only-some-of-my-installed-channels-showing-up-on-my-Plex-app-
If you have already tried this and no channels are producing. Check to see if it is an issue with your client or PMS by opening Plex/Web client (Media Manager). If the channels show up there, the issue is with your client. If not, it is PMS that is giving the issue. You can find answers or post questions in the section of the forum for that client or PMS OS.
Other Things To Check
Did you make sure to delete "-master" from the end of the bundle name?
Did you make sure you put the bundle in the right folder?
Other causes could be the permissions you have on your PMS computer.
If all else fails, you can upload a copy of your log. But if this is an issue with all channels, and not just TV Land, you will need to post that in the appropriate section of the forum.
