Hi, I put an old battery from my das original Canon eos, It got stuck a bit but i got it out ok. I put my battery back in but my camera never came on. I charged it up but still no joy, so I thought that the battery was dead. I bought a new battery and tried that after charging it but that didn't work either. I then noticed a smaller battery which I replaced, but it still won't turn on. Is there a fuse somewhere on the camera as I can't find my book to see.
Cheers, Frank.
