A few days ago everything worked fine. Today I can't change channels. I've tried to change channels by using the remote and by clicking the channel on the TV guide. Neither work. Everything else looks great, picture and sound quality are same. Lucky me, it's stuck on ESPN!

I installed the Beta a month ago and it's been OK. This is something that just changed overnight. I'm away from home, so could my grandson have bumped the box? It's been sitting on top of my cable box for several years.

I sent an email to Sling but the reply was to 'move my IR Blaster." That doesn't help. I don't know what an IR Blaster is.

Thanks for any advice.
