Quoted from Mudflaps:
I learned that I suck at soldering. I also learned (again) that pinball machines don't like to be moved.
We just moved a Xenon we are working on. It was booting perfectly.
We moved the machine from one side of the room to another on pinball skates, so it was smooth ride.
Now all I get is a loud hum from the speaker and the main board no longer boots up. Arrrrrrgh.
