Hi guys,
Glad I found this thread. My tuner was working before but now it cannot find any ATSC channels within MC24 channel scan. I followed the guide and everything mentioned in this thread and still no channel. I can double click on the channel directly from the HDHomerun SetUp program and it will open the live TV channel. I even tried to restore my older library and my TV channels came back up and I was able to view live TV but on the next day or two, it goes to 'Waiting for signal lock...' and then 'No signal'. I would need to run the channel set up again but then it cannot find any channel. I notice after restoring an older library, it says 'Loading program guide...(may take several minutes)' but it never could finish as after a while, it would show Last program refresh on 8/15/2019 (date from last month when it successfully refreshed, I guess). Football season is here and I am trying to DVR my games within MC24. Please help! Thanks.
