I have a Canon EOS Rebel T3. In auto mode it will take photos and the LCD is fine. But in other modes like P, Tv, Av or Manual, half or more of the screen is black.
If I click the photo button again it will correct itself and show the full LCD screen.Then if I turn the dial back to auto, half the LCD is black again etc.
Any idea what could be causing this? This is a new camera to me - it came with an auction I bought.
