Does that slit lamp have a beamsplitter lever that must be flipped to direct
the image to the camera port? Has someone inadvertently flipped it?
Take the camera off and look into the camera port with a brightly lit
subject in front of the SL. do you see anything?

Back to the drawing board. New cables, still no image
MUST be somewhere in the mechanism of the slit lamp itself, as system is
getting power, cable is sending to Camera Control Pro software OK, camera
back works fine when NOT connected to slit lamp, Shutter is tripping, flash
is engaging.
Any more thoughts?

That's it! Shutter, which I always thought was working, confirmed.
Need new cables!
So grateful to tap into all of the expertise!

Denice
Have you tried leaving the camera wired to the SL but taking it off the
mount and holding the body toward a ceiling light while looking into the
lens mount and firing it as you would thru the slitlamp?
This way you can rule out mirrow/shutter issues being caused by the
wires/triggers of the SL. Then you're down to software or FW cables. My
next step would be a different FW cable. We ran into a situation like that
when we tried to connect a trigger cable and there was a weird polarity
issue thar reversed the function of the mirror. It locked up when connected
and DROPPED when the shutter was activated.
FWIW - we shoot with the D200 on 1/250 on our old Zeiss SL, a slower sync
shouldn't matter and i know you said none of that has changed.

Have you tried shooting without the card in the camera? Is there a setting
which directs the output? With our home brewed system we do not have a
memory card in the camera back, only a hard wired connection.

Camera works fine disconnected from firewire, with card

USB and Firewire cable are being recognized by computer as being valid and

However, when card in slit lamp, connected to Firewire, photos are black
Checked settings. Shutter at 125. ISO 400. Nothing's changed

Short term, see if your camera can write to an SD card or whatever card it
uses. You could then transfer the images to your CPU this way.
Specifically, what shutter speed are you using?
Is there an X-synch setting which may have been turned off or reset somehow?
Do you see a preview image on the camera's screen?
I have had cables fail and camera plugs fail. Firewire, especially the
small firewire plugs are more prone to this than USB.
Turn everything off, then spray contact cleaner on all the connections, plug
and unplug those connectors while they are wet with the cleaner. Careful,
it might be flammable and definitely bad to breathe.

Help!
My OLD Nikon FS3V slit lamp camera with D200 Nikon Back
Have double/triple checked all settings on D200
Rechecked, rehooked cables
Flash is engaging
Shutter opens. You hear it
Fireware sending BLACK image to computer. Something is blocking light from
camera to Firewire to computer
Bad Firewire cable? Flash appears to be going off fine. SOUND and setting
of shutter OK
Your thoughts before I cry uncle and spend a lifetime on the phone with
Nikon?
