It's been a few days now that only one channel (44.1) just started displaying a black screen. The channel info says I have full strength and it also displays the current show that is playing and a full description of the show. The channel guide even shows the thumbnail image of the current show running.
The other channel 4.1 works fine.
Does 44.1 still come in OK on other televisions? I'd try re-scanning for signals (Settings -> TV inputs -> Live TV -> Scan for antenna channels) to force a rebuild of the Roku's channel table. That station might have made a subtle change to their PSIP table (e.g. new MPEG program-ID numbers) that's somehow confusing the receiver. I think Roku pulls broadcast program descriptions from an Internet service rather than over-the-air.
