Black Back Display

[rem]

Hello All
Since yesterday I have with my H5D-50 the following problem: The Display from the back remains black.
When I switch on the camera, after a short while comes the "H" and then is the display black again.
t happened yesterday when I would shoot tethered. Everything is working normal so far, I can make pictures tethered and to the CF but I see nothing on the back.
I made also a Firmware DOWNGRADE from 2.6.6 to 2.6.5 (I do not found the 2.6.6 on thee Hassy Website... The "Update was running I think not normal. There was no Info that the Update is complete and I should remove the firewire cable and restart the camera. Just the the window was going.
For sure, I tried the display button ;-)
Any ideas???
Many thanks, Rem

I would try updating the firmware again, other wise I think it's off to Hasselblad.

Thanks Nick, I will. Is there any reset function to factory standard(not the battery)?

Hi Rem as far as I know the firmware update process is the way to reset...
