BINGO!
That was it!
C82 was one of the capacitors that had leaked and I replaced. Right in that
same area is the trace between T23 (Emitter) and Pin 4 of the display
connector. I checked and there was no continuity.
I ran a new wire. Powered it up... and have a nice beautifully functioning
display now!
Thank you so much for your help.
Another M100 returned to life!

On my machine it swings from about 1V to around 3.5V. The 1.25V is way too
low I feel. Is there a good connection from T23 to pin 4? It sounds as if
that line might be disconnect or there is a problem with the contrast voltage
generation.
Is VR1 giving a good voltage input?

With one lead on Pin 4 and one lead on GND, it is maxing out at about 1.25v and
goes down to around zero. Is this acceptable?
Thanks,Chad
