Single channel problem

Anyone experience this problem? NBC hasn’t been an issue until a week or so ago. When I initially start viewing it’s fine for a few minutes and then audio gets spotty and sometimes I get kicked out. If I exit the channel then go back in it’s fine again for a few minutes. If I leave it on longer often the sound stops entirely until I exit and start again. Picture can also be impacted. Recordings on this channel experience the same.

It’s a Roku tv. I’ve rescanned channels and my firmware is up to date. I do go through a receiver. Could it be something unique about this channel? We’ve checked the antenna already.

It really does sound like a signal problem. I know you said you checked the antenna, but I would look again to make sure all the cable connections are good. Also, could your antenna gotten tweaked a few degrees? Possibly an obstruction between the antenna and the towers?

Just some thoughts…
