I have been able to replicate a small issue twice. After pressing the Active button, I waited for the list to populate and once it was populated, I used the screen as a normal user would, by cycling between weather, horoscope ect...
Then both times, I pressed the Exit button to escape, and both times the screen froze and I had to turn off (not reset) the 34 to fix it. Once I turned it off/on, it functioned normally. Both times there was sound, but a black picture and the only button that would work, was the Power button.
I hope I did this in the right area, if you need anything further, let me know!
