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.

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
