Mine stopped yesterday

So does mine and I run the board from a 9V regulator.
The display is built into the same box as the gpsdo

>I left it on overnight,

Mine has been on continuously for over a month

Same thing here

Other errors that I get :

2 lines of date & time
Only one line of date & time on the display
It has frozen displaying only one line of date & time for several minutes

Sometimes displays "TSIP LED Monit"

Ocassionally only the back-light is on, nothing displayed
This lasts for a couple minutes then resumes "normal" display.

There seems to be a pattern developing. Is this an inherent problem
with the processor board or with the software? All together, mine has been in
operation about 3 months which would seem to rule out a software problem.
The occasional  display of "TSIP LED Monit" would indicate that the processor
is being reset as this is normally seen at power-up.
