Chosen Solution
When I am trying to use my Nikon D700 during a shoot my screen started showing 1/4 photo and 3/4 black screen. The screen is not completely black but shows image at top. I tried replacing the memory card and lens and both same thing. Camera is giving “Err” message. Not sure what the problem could be? I have had this camera about 5 years.
Here is the service manual: Nikon_d700.pdf Open it up, and check all connections. It could have just been a blow that knocked the LCD connection out. Might want to give it a quick cleaning, also. Be careful not to damage the sensor. This camera is worth fixing. Despite its age it has its bit of personal room in the camera world.
