Ok, some folks may have read it already, tonight I had the best chance I have had in ages to get the scope out.

Then as I was running through the alignment process, my 4yo son stuck something metallic in the PC port of the mount and it promptly failed. I now seem to have a multi thousand dollar door stop.

The hand controller gives the "initializing" display then goes blank and stays that way. The board in the base of the mount simply has a couple of ports on it, plus an RS232 chip and a buffer chip. It seems tha it is not talking to the motor control section, any ideas on fault finding?
