Mine does it via the epg and selecting a channel. I usually don’t use the +\- channel buttons so don’t know if it does it that way too

I’ve noticed the black screen with buzzing noise aswell. I just got the u5 a couple days ago and it updated to the new firmware right away so I can’t compare to previous version firmware. Doesn’t happen all the time, I think it’s happened maybe 5 or 6 times in the last couple days. Not a huge deal. Switching the channel and going back fixes it.
