Question Monsoon Head Unit - no lights, no volume

I finally got around to replacing the bulbs that light the display on my 2003 Monsoon head unit. Put it all back together and now the unit is completely dark plus the volume knob does nothing. The Steering wheel controls work fine and the radio works and the CD player buttons work and CDs play, just no lights and no head-unit volume control.

I changed the radio/batt fuse (though the existing one looked fine) but it wasn't that.

Before I take it all apart again and get in there with a multi-meter (which I'm not looking forward to as the harness will have to stay attached), can anyone tell me what the problem is or is likely to be? At this stage I'm figuring I must've messed up the harness/connector somehow.
