Hi, my daughter's 250 lens cover, spring loaded in 2 parts sticks closed, i.e. doesn't open fully when camera turned on. You have to flick it open manually. Tried blowing etc, but can't fix. Can the lens be dis-assembled?
Thanks for any help.

Re: Lens cover jamming
Try blowing lots of compressed air around the open lens shutter to clean the mechanism. Or use a hair dryer for a few seconds (don't want to heat up the camera). Also 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. A grain of sand in the mechanism is usually the culprit, and you want to try to dislodge it.
You can open it up, but only as a very last resort. The above procedures usually 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):

It's usually merely a grain of sand or dust jamming it. But it's also usually easy to fix. This link outlines repair techniques for a stuck automatic lens cover. Recommend trying the less "risky" ones first before considering the end of the lens.
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. There are many non-invasive techniques that people have come up with to accomplish this. Some may be seen on this blog article. You can also open the lens barrel up to fix the covers, but only as a very last resort. The article also gives examples for this type of procedure.
I have just had exactly the same thing on my daughter's NV3.
In this case the lens cover would not open but if you power on the camera with you finger on the display button you can view stored images.
If the lens cover is jammed you need to open the casing and maybe take the lens cover assembly apart. You need a very small cross head screwdriver (No.00 should be OK). There are 5 screws in total, 4 screws on the outside of the case (3 plus1 under the headphone socket cap) and 1 inside the battery compartment. You need to remove all 5 to remove the camera front casing. There are some retaining springs top and bottom on the front cover, gently prize off to reveal the lens cover assembly.
Check to see if the lens cover will operate by switching on and off - if it works then the camera front casing is preventing it from opening and is probably bent out of shape. A little careful bending back into shape should resolve the problem. If it still does not work with the casing removed, read on.
This is the tricky part. There are two extremely small, black retaining screws to the left hand side which hold the assembly onto the lens cover motor. Remove these screws and the front of the lens cover assembly to reveal the lens cover and the back plate of the assembly.
Lift off the lens cover and switch on the camera. If the motor is still working, you will see a short black peg move from side to side as you turn the camera on and off. Thoroughly clean the lens cover and assembly, remove any obstruction and replace the lens cover making sure you locate the hole in the lens cover over the motor peg (described above).
The motor is magnetic and will attract the screws away from their holes if you replace the assembly front straight away, so when you replace the front of the lens cover assembly, place the screws in the correct holes before lowering it into place and then screw onto the motor/assembly back.
Test that the lens cover opens and closes and replace the Camera front cover taking care not to bend it too much - if this becomes distorted it can stop the lens cover from operating resulting in the same problem.
When you opened it the cog connected to the motor which opens and closes the lens probably shifted and no longer has traction against the ring around the inside of the lens which turns it to open and close it. If you open the camera up again be extremely careful - the lens has loads of springs inside it - lose one of these and it won't work properly. I opened up the whole thing to try and fix my lens which had been jammed in after a friend dropped it. I fixed the lens but couldn't put the damn thing back together again to many tiny parts and no guide to the jigsaw!!
I recently had the lens cover stick partly open. There are 4 segments to the lens cover, and if we number them from the top, number 2 was not closing. I gently flicked the segments a few times, in case there was a grain of dirt causing it to stick (although the camera has never been in a dirty or dusty environment). This caused the lens cover to close fully each time, but now it would not open fully, segment 1 would not open, although it would stay open if moved by finger. Anyway, after a bit of fiddling, I got it working properly again. The way that the lens cover appears to work is that only segments 2 and 3 are pushed open or shut by springs, segments 1 and 4 are pushed open and shut by tiny tabs that catch on segments 2 and 3. If the segments somehow get pushed out of alignment, then they either bind (causing the cover not to shut), or they get disconnected (causing the cover not to open fully. Now I am not sure exactly what I did to get the mechanism form the stuck open state to the not opening state, but from there the way to fix it is to: -With the lens open... - Hold segment 2 in the closed position with firm finger pressure (which will tend to push it towards the lens). - Push segment 1 towards the open position until you can see that it has cleared the edge of segment 2. - Lift segment 2 way from the lens so that it will rub past segment 1 as you... - Move segment 1 to the open position. - Repeat if necessary to get the technique right.
I can't provide any guarantees, and I am not about to repeat the excercise on my camera, but it was a lot easier than sending it off for repair.
