My friends puppy(mega police dog pup) got a hold of my canon powershot a 480. Cracked the screen. Everything still works, just the screen is cracked, and can only see about 40% of it. Is there a place I can find a replacement screen? Took the cam apart and removed the screen and put it back in so I know I can fix it if I can find a replacement. Thanks for any help as I cannot afford a new cam.
