Newbie question - My entire stereo unit has stopped working. I was fiddling with my cell phone charger under the stereo, and I tried using the stereo afterwards and it won't turn on. None of the buttons work. Is this a fuse thing, or something much more severe? Not sure where to start (other than the fuse panel which seems like as good a place as any!).

Thanks!

 

Definitely check the fuse first.
