Hi,
in a normal point-scanning confocal there is no critical alignment in the
excitation path. I've seen come weird configurations (e.g. old Nikon PCM
2000), where both excitation light and the emission was directed through the
pinhole, there a small misalignment can result in complete loss of
excitation light. But I think FV1000 is not the case.
It must be either some safety shutter or the scanner is in parked position.
Can you hear the scanner?
Good luck!

Listers,
according to suggestions from Olympus Americas and Avi Jacob (thanks!), I
have compared power measures with the internal light power meter (LPM) to
earlier measurements from August last year. All 6 lasers except the 405nm
line (39% but I noticed weaker signal and de-focus here before) show full
power (99-100%).
Both red LED's on the right side of the scan head are ON.
(filter turrets manual shutter open, filter block in mirror position1).
Still no light out of the scanhead.
All further suggestions welcome!
Very happy about the listserver!
Jens
Abraços,
