Faulty 4th MFK LCD display

Recommended Posts



On our solution desk we have had a recurring problem since purchase where the 4th MFK display is not displaying anything, however it is being backlit.


At first i believe it had been working, then a few weeks into use after installing the latest version of ZerOS and us noticing the problem we reloaded the desk back to the earlier version of ZerOS at the recommendation of the phone helpline (many thanks), which seemed to fix if temporarily but after a short while we noticed the problem again.


There is also no confirmation if it was actually fixed by the software backdate, as none of our operators are sure if there was any difference made, or if it stops working after accessing certain functions.


Has anyone else experienced this or similar problems, and is it a software or hardware issue, and if so how can it be resolved as it is making it harder to access such as blind mode.


Many thanks in advance
