Heh... Now that I understand.

I took another look at it today. In the cold harsh light of morning I found the little bugger. It's the fairly obviously fried component in the supplied image.



What is that thing? It is fairly close to where the screw ended up, so I assume that might have been the culprit. I'm guessing replacing that little thing would be fairly easy for someone with any soldiering skills. Sadly, my only experience is some ham fisted radio repairs with a wood burning kit. . Either I have to find a local electrician I trust with my baby or wait for Rob to be available for a fix I guess...

Thanks for helping me through this sad time.
