If the problem is only FA related, it is most likely related to the filter
solenoids. Sounds like one of the solenoids is sticking or failing. But here
is where you need to do further differential diagnosis.
1. Does the problem occur if you leave BOTH filters in for the entire
angiogram? You can run a dummy angiogram or 2 to test this. If the camera
works, the solenoids or switches are obviously the problem.
2.You might try leaving the exciter filter in and letting the camera insert the
barrier filter automatically for a few FA's. If you get no errors, reverse the
process. This should narrow down which filter solenoid is failing. It should
also offer you a temporary fix (i.e., shoot FA's in the mode that works until
you can get a repair done). If you get failures in both modes, the problem may
not be the solenoids themselves but the circuit board that triggers them, or a
sensor that waits until the filters are seated to fire the camera.
The other camera is a bit trickier. Your description implies that the trigger
is not sending a signal to start the photographic sequence (send relay mirror
up, fire flash, grab picture to computer), but I would check all the
connections (fundus camera to relay lens, digital camera to computer, anything
else you can jiggle). The wires in the camera that run the joystick trigger
are small, and the welds can break, but if that is the case, it won't be long
before an intermittent problem becomes a permanent one.
If all else fails, call Topcon.

Subject: [optimal] Topcon error codes and misfiring
Hello colleagues,
I am having problems with the IVFA filters on the
Topcon
TRC-50DX .
The camera suddenly stops working and I am getting all kind of error codes
(3,6,8,10..). The first 2-3 IVFAs are fine but then the problem acts up. Maybe
it is heat related ?
I tried different settings, manual filter insertion, etc. but it does not help.
Letting the camera rest, turned off for � hour seems to help.. but obviously I
don't have the time for that. Obviously it is only IVFA related.
Maybe someone had the same problem and can tell me how it was solved. New
solenoid put in ? My local Topcon rep could not fix it.
Incidentally another Topcon in a different office is also misfiring. Meaning
sometimes you have to press the joystick button several times before you can
hear the mirror move up and a picture appears. I may get several blank (black)
pictures on the screen and then a good fundus picture.. I am not sure if the
problem is in the joystick or the eye piece head ?
Again this doesn't happen right away, usually on the 3rd or 4th IVFA.... This
happens not only when doing IVFA but also when just shooting fundus
photographs...
Any help is very much appreciated.
Thank you
Peter

Peter,
Not sure if this might be related, but check all the relay lens and
digital digital back to computer connections. On ours, I had a problem
a couple of months age: pressing the joystick button caused the flash
to fire, and it sounded like a regular good exposure, but a black image
would appear on the monitor. Turns out the cable from the relay lens
was plugged into a computer cable, but the connecters were not screwed
into each other. The slightest tension on one would cause the above
problem.
I don't recall if there was an error code.
One thing to add to your troubleshooting list.
Tom

Did your troubleshooting fix your camera? If not let me know and I will ask
around for you.
