I don't understand why when I turn my camera on that I receive a black screen, and a code of ec18 at the bottom left corner of the screen... this is an older camera and not on the website so your assistance is greatly appreciated!
I can find only error E18 for canon cameras - E18 means there's a problem with the lens cover not opening, and this would explain why the screen remains black when you turn the camera on. Look at the front of the lens with the camera turned on and most likely the cover has not opened.
