TBS 6902 DVB-S2 satellite tuner won't scan for channels

[JJMDoherty]

I have a TBS 6902 dual DVB-S2 tuner PCie card that I have used for a year now in my HTPC with Plex, which worked beautifully. However I upgraded my HTPC mobo, CPU & new GPU recently and the tuner is no longer working. While Plex can see the tuner and I can get as far as scanning for channels, no channels are found.

I have checked drivers and all the usual stuff, installed the DVBDream software and was able to scan for and find the expected channels (Astra 28.2) with this software, so not a sat dish or tuner card issue per-se.

In the logs I see the following lines related to the attempted scan but don’t know what they mean.

Can anyone shed any light on this for me? Thanks all

I’m going to answer my own query and say that I believe what resolved the issue for me was repairing the database (despite this being essentially a new build) using the following Plex guide: Repair a Corrupted Database | Plex Support

Hopefully this reply will be of use to someone who is having a similar experience.
