I have been encountering an issue with my Canon 5D as of last week and its been doing it repeatedly with use between then and now. I will turn the camera on without a problem, but then after a few shots or after its been on for a few mins the screen will go blank except for a blinking battery, which should normally indicate a low/almost empty battery (no dashes indicating low level of charge), but I have tried fixing the problem with three different fully charged batteries and that doesn't seem to matter, I keep getting the same error. Then I turn the camera off and the battery error still blinks, until I open the battery door. I never know when its going to occur, it happened during a shoot and then started working again the next day. The camera will not shoot an image after this error occurs. Help! I've had it less than a year and can't find anything in the manual about this indicator outside of low battery level. Has anyone had this same issue?
