Hi
I went to plug in a usb to the rear of talkshow, and it wall all by feel. Not ideal I know but done it a few times as I fumbled it must have 'crossed' something as the unit just died like fuse had blown or something. The unit is now as dead as it if was unplugged.

Any ideas?
Is there a fuse - on mother board for example?
Any help appreciated thanks.
