Just starts to spin up and then freezes. Netflix andother apps still work. Works on other devices. I tried resetting the cache. Still nothing. Thoughts?
I had the same problem. The solution was to do a factory reset on the TV (Press Menu | System | Reset).
Rebooting didn't help. Removing the app and adding it back did not help either. There is no way to manually update the TV's firmware -- updates happen automatically while the TV is turned off. The last resort was a factory reset.
The downside is that you will be starting from scratch and need to re-activate all of the applications, etc. That was 20 minutes of fun.
