I suggest you do a "Reset"
You may have inadvertently set something that is keeping the LCD set to Menu.
Here is how you do a Reset:
Look in the User Guide (Advanced).
At the back of the User Guide you will find an Index.
Look for "Reset All".
Perform the Reset All and it will reset the camera to the factory settings.

For some reason my camera viewfinder screen will not show anything except my settings, neither B-4 I shoot or after on review. The light blinks stating trouble focusing as well. My batteries are fully charged and I cleaned all the terminals. Any suggestions will be appreciated. The camera is about 5 yrs and only about 300 pics taken. I've reformatted my card also and no luck.
Thanks in advance, Howard
