Need service manual info for,powershot shot s50 sliding lens cover door replacement,mechanical parts.Electronic parts and diagrams.I have disected to by pass power switch,was working for a while but now im getting nutskins would appreciate it if some one has this info thanks so very much .
I have been having the same problem. Once opened, the sliding
door will not close and the lens won't retract. But I have found
that if you plug the camera into a computer via a USB, the lens then
retracts enabling you to close the lens cover.
I'm still trying to find a way to fix this problem, since this is a great camers and still takes fantastic pictures.

A stuck lens cover is a fairly common problem, but it is normally easy to fix. A single grain of sand jamming the cover mechanism is normally the culprit, and you want to try to dislodge it: 1) Try blowing lots of compressed air around the lens cover to clean the mechanism. Or use a hair dryer for a few seconds (don't want to heat up the camera). Use no heat mode if possible. 2) Slide a thin strip of paper between the lens cover shutters and the outer support ring. Work it around 360 degres to clear out any debris that may be in there. 3) With the lens barrel extended and pointed downward, tap the lens barrel with a pencil while you extend and retract the lens by powering the camera on and off. Repeat the above three steps several times. If repeated tries don't work (keeping in mind that it usually does), it then may be necessary to open the lens barrel to access the lens cover mechanism.
You can open the lens barrel up to fiix the covers, but only as a very last resort. The above procedures normally work if you try them enough. But for those particularly nasty stuck mechanisms, here's an example repair on a Canon Powershot A400 (do this at your own risk, and it will void your warranty).
Canon E18 error happens when the lens gets stuck while trying to extend. The camera will beep a few times and the LCD will display a little E18 in the lower-left corner. The lens gets stuck in the extended position, and refuses to move either to focus the lens or to retract when powered off. This is caused by dirt in between the telescoping portions of the lens. You can clean this with compressed air, generally. Blow air all around the turret sections of the lens. you can also GENTLY push the lens inward ( have the lens extended and take the battery out... then push inward...)
I had the same problem with a S50, where the lens door would not operate properly and would not open enough to cause the camera to activate. I took it apart and found that there are two small gears that keep the door on track, one had split in half and jammed the mechanism. They were white plastic, perhaps nylon? I found another S50 on ebay with broken electronics but a working lens door and took parts from it to fix my system. Getting the tiny gear in place was tricky as there are several springs used to activate the camera on switch.
The open door button on a circuit board is usually micro. A loose cover will likely not make contact with this small switch. Take the cover off and tighten the screws on the inside. Try to locate the switch to inspect if it has been wore off, broken, or missing even.
There is a common problem with the A series Powershots, that the lens assembly jams in the telescoping zoom, or in the digital imaging module, in which the lens assembly has to be replaced. I'm not sure if the S series has these issues. You can check with Canon support to find out.
