Right at 6 PM tonight, I lost 8-1 on all my TVs. 8-2 and 8-3 are coming in fine as usual. I am not sure what happened, but right as PBS Newshour should have started, the picture started bouncing on the screen and I could hear the audio of 8-3 coming through. I've not been able to get it back on any of the three TVs.
Is there anything that could likely be wrong at my location that would cause WGTV 8-1 to go out, but still allow the subchannels to be coming in just as before?
