Advertisements Every 2 or 3 days, I will back out of an app and the Tivo S4K just goes to a black screen and sits. If I hit the "Netflix button" on the remote, it will open Netflix, but if I back out of Netflix I am right back to a black screen. Only solution is to unplug the Tivo and plug back in. Apps I know it has happend to are when backing out of Netflix and Pandora. I'll pay attention to see what other apps it happens to. This started maybe 3 weeks ago. I have the latest software. EDITED TO ANSWER QUESTION BELOW: Yes, it is plugged in using the included wall adapter into a wall outlet. Any ideas?
