I own an all-in-one camera: a Canon Powershot A710.
I'm not aware what happened exactly, but now the automatic cover (the thing that opens when you turn on the camera and the lens pops out) is sticky and it doesn't always open I have to either wait or push it.
I've tried using alcohol and some cotton tip, and it works for a little while, but then it gets sticky again. Are you aware what trick could I use to fix this?
Another option would be to open the lens and check what it is that gets it sticky again, but I don't see an easy way to open the lens in this camera.
Any suggestion is very welcome
EDIT: Finally I discovered it was indeed a sticky substance. To discover that I played with the side that got stuck when closed and pushed slightly so the edge touched the rail on which it's mounted. Doing this I discovered that a section of the rail was indeed sticky, it didn't feel like dust, because the stickiness was only on a small portion of the rail, after that portion the cover moved normally. So I applied a bit of alcohol with a tip in the section of the rail (this is, cleaning the rail, on the side of the lens entry, not directly on the cover nor on the lens of course) that had the stickiness and it's been working correctly for a few hours now, which had never happened before.
