I have a Canon 600D. I have had it for almost 2 years I think (not 100% sure). It was working fine for most of the time, but recently I think I had left it on and drained the battery. I recharged the battery and now it doesn't turn on. How can I get this fixed? Also, I had a SD card shell break while in the camera and I used something to get it out, but now that I shine a light in I can see that one of the pins is bent. Could this be the problem?
