I had a problem where the camera (Optio A20) would power up, the startup screen would flash on, the lens would come out, then about 3 seconds later it would go back in and the camera would shut down. Figuring that it'd be too expensive to get it fixed, I went at it with a suitably small screwdriver. It turned out to be a jammed piece of the lens mechanism, that was surprisingly accessible.
I did the following:
1. Remove the battery. Remove the casing (4 x screws by the power/data sockets, 5 on the bottom. The side panel (nearest the lens) should then come off with a little persuasion, revealing another screw which is holding the top panel on. Remove this with a little more persuasion.
2. At this point you should be able to pry the casing open from the base of the camera and remove it (You can open it more carefully, but I didn't damage my case by prying it). Don't be too rough though. A loose plate may fall out, that you'll need to replace when reconstructing the casing. Don't forget the position of this as it's quite important in holding everything together! There should be a little pad on it though, and this goes face down, nearest the lens.
3. Now you've got the case off, look at the base of the camera, next to where the battery slides in. There should be a little metal plate that's kind of clipped on, with a little peg nearest the lens. This is covering part of the lens mechanism, and in my case, this is where the problem was occuring.
There's a big orange bit of circuitry under the screen (you'll see it if the screen falls out - don't worry if it does by the way, so long as it's connected and hasn't been damaged it's fine. Just make sure you're nice and gentle with it). Anyway, this circuitry drops into a slot on the base, right next to the very fragile spring that you don't need to touch. On my camera this was loose and I think that this was part of the problem. Powering up the camera without it in place caused all kinds of problems. Anyway, I ensured that this was in place, and near to the fragile spring I mentioned earlier, there's a metal pin, with a piece of black plastic on it. You might not see it, but it's also attached to the fragile spring. If you get a small flat thing (a screwdriver is ideal - a really small one) and just give it a nudge, then power it on, the mechanism should unjam (which solved my problem). Note that I've put the battery back in a couple of times here to make sure that the problem is solved. Don't worry - so long as you're not touching any electronic bits, you should be fine.
Putting the case back together was a doddle too, so long as you've put your screws in an organised line, so you know what goes where...
