I have been searching the forum looking for an answer, but firmware and driver update doesnt seem to work. I am starting to believe my unit has some problem initiating the screen (everything works fine except for the screen). I managed to make it work after firmware upgrade but next time I turn it on it fails again. I am from Spain and I´d like to know where could I send my unit for repairement in case of need. I will try to revert the firmware to an older version to try if the new firmware is the reason it failed to work but I dont think this is a reasonable solution for a profesional product. Best whishes, I will update any changes.
