RE: HP41CX, not working.
Hi Didier,

thanks for your accurate information.
From my side, the Display Driver is a diagnostic by exclusion.

-Many zebras tested.
-Many flex (including an original), tested
-Board switched.
-All connections fine and tracks free of oxide.

It is curious because you usually get a flash or a couple of seconds of "good" connection that gives you a clue of the problem. This has never happened, which means that is something that is present all time. Hence the display driver more science behind.

thanks again and kind regards,
