I have a Nikon D70 and I have never had any problems with it. One day it was working fine and the next day with nothing changed it started having problems. What happens is with no settings changed and on Auto or Manual I will take a picture and #1 may be fine, #2 will be blacked out, #3 fine, #4 blacked out, #5 everything will be whited out. and so on and so on. I have checked all settings and just can't figure out what happened. Any help would be great.
