Question about Olympus MJU 300 Digital Camera

1 Answer

Lens will not come out of camera

When I slide the camera open, the lens will not twist out. In fact, nothing even turns on. With the cover on, the quick view will turn on and show you pictures that are already on the card. It is the actual picture taking that is the problem.

    I have the same issue - i was using the camera at a concert and kept putting the camera in my pocket where I think the lens cover may have got something jammed in it - I have tried to clean it, but have not yet taken the cover off , so will give that a try and see what happens.

    Olympus mju doesn't switch on when cover retracted.

    Have removed the cover but the on/off switch doesn't seem complete.

    Anybody any ideas ?

    Anybody changed the switch ?

    Any ref. manuals/diagrams out there ?

There is a workaround for this problem, when the lens cover is open press down on the area of the lens cover on the "s" of Olympus. This can operate the switch that opens the lens etc. The long term fix is to remove the lens cover by removing the 2 screws at the base of the lens cover, take the lens cover off and gently clean around the switch which is behind the "s" of Olympus when the cover is on. I found that the grease/oil Olympus had used on the switch attracted dust etc and by cleaning this off the camera began working. Be careful when taking the lens cover off, there is also a very small metal plate that separates from the lens cover - don't lose it.

My camera turns on by itself even with the slide in front in the closed position. The screen then shows the warning that the lens cover is closed. When I open and reclose the lens cover in 10 or so...

Most likely some dirt, dust, or other particle is jamming the lens opening gears. You can try to spray some compressed air into the lens assembly, hopefully dislodging whatever is obstructing the lens cover. If this doesn't work, the camera will have to be serviced, which can be expensive. If the compressed air doesn't work, and you decide to have it fixed, get an estimate first. Often the cost of repair justifies going ahead and purchasing another camera.
Good luck, thanks for using FixYa, and hope this helps!

The lens cover does not open all the way. I have to use my fingernail to do it.

It is either bent or has grit and dirt in between the slides. Try using canned compressed air, such as you use to clean a computer keyboard with, to blow air between the slides. If that does not work, even though you will have to be very careful, while the lens cover is closed put a single drop of WD40 on the cover and spread it with a Qtip over the entire cover surface. Holding the camera, front facing down, try turning it on and off several times. If that frees the lens cover, turn the camera off and wipe the surface of the closed lens cover with a soft tissue to clean the WD40 from the surface. Make sure then that your lens is clean before using the camera. If the lens cover is bent, then none of this will work.

Power problem

Oddly enough, as I was looking at this thread, I was fiddling with the camera and it decided to turn on when I opened the lens cover. Obvoiusly, 2 minutes earlier, it wouldn't come on, as that was why I looking at the forum!
sorry, I don't have a solution, but I suspect there's an issue with the contacts in the lens cover. Every moving part will have an Achille's Heel, I suppose.

Camera powers up but lens cover fails to open

It could be some grit or sand causing the lens cover to not open, so the camera won't initialize. Try cutting a slip of paper narrow enough to slide between the lens opening frame and the lens cover. Move it in and out to clear any grit that might cause the spring-loaded cover to bind. Good luck !

Lens Cover Closed

the switch inside that activates the camera is probably loose, or worse, broken.

Cover open, camera does not turn on.

Completely open lens cover by sliding the lens cover all the way to the right until you hear two clicks. The first click will put the camera into playback mode. The second click will put the camera into shooting mode.
