Subject: OSBORNE 01 Video Problems

 I have an OSBORNE 001 with the external video option and monitor.  The
external video worked for a while. However, it has not worked since I ran
the CP/M SETUP program (to change a printer device). This may have been
coincidental with unplugging the external video connector while the Osborne
was powered on.

 Does anyone know if there is a common problem that might occur with the
Osborne video output? How can it be fixed? Are any circuit diagrams available?
I'm confident that the CPU and other circuitry are okay.  The problem seems
to be in the video output.

BTW, I don't have the plug marked "Warning do not remove with power on" so
I can't try the internal monitor to see if that works.

Any help would be appreciated.

Thanks,
