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 guess...no more science behind.

thanks again and kind regards,

Ignacio
