Cap Cover Canon
How I can fix my camera? It is a Canon SD 750?

The lens cap fell off, and the two rounds of the open goal to turn the camera do not open or close more. I have the 2 small screws that fell off too, but I'm not sure where to put. The camera is turned on, and zoom and works things. The only problem is that the lens cover 2 things did not open because the two small screws came off, the lens cover and fell. How I can fix? I'm pretty sure I can fix it myself, I do not know how to achieve the objective turns to open closed when the camera turns off and on. Suggestions please?

Ok. First, to understand the purposes, there is a ring around the tip of the lens called the lens ring. There are two plastic parts such as door that open and close the barrier is called the lens. And the goal has two (if any) the segments that develop and extend called lens barrels. It sounds to me like ring lens and then extracted from the extracted lens barrier (below) and two screws you speak of are the two met in the barrier mechanism. The ring of the lens should only stick in the afternoon with a small amount of "Pliobond" glue. Technically, the camera should work if what you say is what happened. Just be careful not to scratch the front lens element (the "glass" on the front piece of the lens).
