Display Flickering

[badstarfalling]

Hey guys,
I just got a Zune v2 80GB, and I have noticed that the display flickers on and off randomly while it is playing music. Here's the scenario:
Playing my music, the display goes off after one minute as per my settings.
Than a few minutes later the display lights up all black. No album art, not showing what's playing, and not any menu window.
WiFi is turned off, so it's not some weird "connecting to another device" thing.
It doesn't do it at song changes, just randomly.
It's not any big deal, just was wondering if it could be the warning sign of something that might go wrong eventually.

Thanks for any ideas that you might have.
