Galvo problems on FV300

[Martin Wessendorf-2]

Dear Group--

We have an Olympus FV300 that we've used for a multiphoton microscope.
After disassembling it to move it to a different room, the galvos no
longer would scan: in fact, the mirrors jammed into each other and a
fuse on the scan board blew.

We unplugged the galvos and checked the voltages going into them.  We
found >20 volts to pin 8 on the plug to one of the galvos (M-, according
the the spec sheet for the galvo) and 14 v. on pin 5 (AGC).  The other
pins showed little or no output.

Any thoughts on what the problem might be--or more importantly, the cure????

Thanks--

Martin Wessendorf
