Record in darkness

Hi, I have a problem: in afternoon, camera can show image, but, when I press “Record” - only black screen. When record is interrupted, I can see image again.
Can someone help me? Thanks.

Of cause. However, I need more information to reproduce this. When do this happen? Is it for a specific camera or for all cameras. Post a picture also. When you press Record and the screen gets black is it recordong to a file that you can view?
