Broken Lens Cover Mechanism

The lever that opens the lens cover no longer functions. It was jammed and then when I tried to fix it, something inside has obviously broken. I have tried to take the camera apart by unscrewing the obvious screws inside the film chambers and this made it almost possible to remove the front camera casing. However the casing still seems to be fastened on the lower corner at the shutter release side of the camera, and I can't see how to open the camera fully without breaking the casing. I just want to be able to take more pictures with my beautiful camera and don't mind if it means taking out the lens cover altogether. Any solutions gratefully received to either fixing the cover, opening the camera or where I might be able to get someone to look at this unusual camera. Thanks DT, London, UK

SOURCE: lens cover stuck open

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.

You may have the same problem that i had. It does involve taking the camera apart. Not overly difficult - just fiddly.
Let me know and i'll talk you thro' it

SOURCE: Camera lens cover will not fully open

Maybe not a remedy for everyone but, I tapped all around the lense with a soft wood ruler stopping to turn the camera off and on periodically. I noticed a lot of sand, we live at the beach, came loose. It took me a little while to do this as I was being caeful not to damage anything else on the camera. Finally, the cap just opened and has ever since. Good luck.

Shutter is not opening in PL-90

A stuck automatic 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:

METHOD 1:

Point the camera straight down into a vacuum hose (while the vacuum is on) and tap it around the insides. This will help to **** the dirt out instead of pushing it in further like compressed air might do.Also turn the camera on and off constantly while doing this.

METHOD 2:

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 degrees 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 then it may be necessary to open the lens barrel to access the lens cover mechanism.The lens cover mechanism is usually accessible for many cameras without needing to open up the camera case.

The plastic pieces that cover the lens doesn't close completely without help from me. Is there something I can do?

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 in this 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.

The Lens

Hey, bad news for you, the mechanism seems to be jammed, fixing this yourself can be really difficult, I have tryed and failed.

I would recommend takeing the camera to a local electronics or pc repairshop for analysis.

Warranty doesnt cover this problem.

Lens doesn't retract when cover hits it. Only way to get lens to retract is to take out battery, put it back in, and then the lens slooooowly retracts, but will bounce back out if cover is closed...

The original problem was a camera with jammed lens mechanism or faulty lens motor. I think the camera had been replaced.

The following post is directed to new users following up on this thread, as the original problem had already been sorted:

When the lens will not retract and camera is not functional (no picture on display, and does not shoot) , and you already tried replacing batteries with a new fresh set (ensure please) , and then restarting camera with no memory card inside, then camera is faulty.

Try an easy fix by pushing gently the lens (do not force them, just help them) while you turn off camera at same time. Try also switching the mode selector.

If still no luck , then the camera must be disassembled to fix the problem.

Possible reasons are :

  • Faulty lens mechanism or jammed lens (camera usually turns off by itself in this case)
  • Main board faulty.
  • Ribbon cable to main board broken or connector defective.
  • If there is no power at all it is the connector from batteries to main board, this is also a ribbon cable.

If the camera is less than one year old will be replaced by manufacturer.

If your warranty is expired you can get an estimate for repair from manufacturer, or from a third party like Advance Camera here :Advance Camera Repair you can book the repair online.

The lens cover wont open

If debris like sand or dirt get into the mechanism which closes that cover it will jam shut. Try gently placing something pointy in the gap between the two blades of the cover. Do not force them apart, if this is going to work they should free with very little pressure. Be very careful not to touch the lens especially if you are using something metal to separate the cover.

Lens cover

I know this is an old post, but for those who want to fix it themselves: 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):
