All ATSC 3.0 channels in Los Angeles NO video data

[brewerbart]

Starting Dec 18, 2025 at 4pm all ATSC 3.0 channels not tuning in. Show NO VIDEO Data on HDHomerun. Get all ATSC 1.0 clean. Wondering whether my Preamp is going out. Or towers not broadcasting low power.

The first thing to do is to run a new channel scan. That will pick up any PLP changes.

Thanks. Rescan fixed it.
