Server Version#: 1.20.4.3517  
Player Version#: 1.20.4.3517  
Tuner Make/Model: Silicondust HDHomerun Dual  
Guide/Lineup name:  
Using XMLTV?:  
Channel number/Name: All

When setting up a DVR, Plex discovers my tuner but says “No channels”.  
The Scan Channels button doesnt work - nothing happens when clicking it.  
The tuner is working and connected. I have checked that my channels are playing via the HDHomerun software.

Howdy! Had similar issue as well. I believe it is a new update since we had issues around similar time. Thankfully I fixed it!

My method of attack was as follows.  
First I advise trying the repair function. In Windows quit plex, go to add or remove features in control panel. Click plex and click uninstall. A window will open, click repair. Reboot and try again. If that doesn’t work try this:

1. Rollback plex to later version. (1 version older worked for me) [How do I roll back the version of Plex?](https://forums.plex.tv/t/how-do-i-roll-back-the-version-of-plex/447470/6)
2. Initiate channel scan, should work now. If not try one more previous version.
3. Once channel scan is complete (hopefully) check your guide to ensure they are present.
4. Check for updates on Plex and update it if prompted.

This method worked for me and I am now watching OTA via plex. Hopefully it works for you and others as well. If not feel free to get back to me and I will be happy to help. If it works I’d also love to hear the good news.

Good luck! -Aidan, I.T. and Network systems administrator at local High School.
