I recently observed that the LCD screen on my Datum / Symmetricom TS2100
is BLANK (all green, no black data display).

It will be a few weeks until troubleshooting issue (?? voltage, backlighting, dead LCD).
Has anyone been down this path earlier.  Known LCD swap/replacement — IF it is bad?

It seems that LCD displays have a pot to set contrast. If this is the case
with your potentially the pot has gone flakey.
A simple readjust may clear up the issue.
Good luck
