Radio froze, 2nd day no menu/audio 3rd day all black!! NO DRIVE!

It was a blown DOME fuse (didn't notice it didn't work either). Got my locks, MFD, DOME all back working but STILL no response if I press audio, menu, info buttons. I don't have the CD player plugged in but shouldn't matter.
I think it's the circuit board which has failed, it makes sense, I have stabbed at the 'info' 'menu' and 'on/volume' knobs hundreds of times.
THIS CASE IS CLOSED, I reckon. THANKS to everyone for replies! Hope this post helps the next person in a panic with similar issues, moral of the story, check all fuses and make sure they're not blown or simply removed! Some are supposed to be missing but not the AM1 fuse!
