    We had this with our first camera. Happened so often (usually during important events like christening's, weddings, birthdays) that we got the camera replaced with a new one by our photo store. This one has been better but overall this camera has been a disappointment especially for the price paid ($650 in Canada in fall of 2004)

Samsung L77 shutter stuck

Something is loose, worn or broken in the shutter mechanism. Repairing these is a lot of work. If you have photos you want to save to another device, see if the camera will permit it even with the shutter fault. It may be a better use of your money to transfer the SD card to a different camera and hope you can upload any photos through the other camera than to repair this one. (If the new camera tells you to reformat the card, do not do so if you are trying to recover any photos from it. Once you have recovered the photos, you can let the new camera reformat the card.)

Camera shuts off after pressing shutter

Manually turn off the camera, remove the batteries, press the shutter release a few times draining any residual charge. Replace the batteries give it a go. It the issue continues it well may be something wrong with the shutter release.

Start simple and go from there.

I don't know if you have film in the camera so I'll read the following and choose what works for you.

I will assume the battery is working if applicable.

As stupid as this sounds press the shutter release button. If the shutter is cocked it will hold the advance. I've had people come in with this problem.

Not it?

If the film rewind has been pressed in it will disengage the film advance and stop the shutter mechanism as a result. Open the camera and close the back again resets the release.

If there is film in the camera remove it.

It there are important photos on the film and your rewind is not working use a coat to make a light proof black box. Just turn the sleeves inside out and put the camera in the coat. Wrap it so as it is closed to light. Open the camera remove the film and roll the film back in by hand.

OK so now we have a camera open with no film in it.

Open the back and look just below the shutter. On one side will be a very small "lever". This tells the camera that the film has been advanced and the shutter is cocked. Gently move the lever to the right. It should click. Now try pressing the shutter release.
Note that without film in the camera some cameras will not advance the shutter.

It should clear the problem.

If not something physical in jamming.

The film advance system could be jamming. On the side the film advance is on there will be a plastic "gear" inside the camera. Try moving by hand it should turn. You can reset the shutter this way.

Give this a try.

Hope this is helpful, if it gives you some direction please rate this answer.

Please turn camera off and then on again. it

Had the same issue with my DMC-FZ50 for a couple weeks, and tried turning it onn and off countless times. I could hear something happening inside the lens on start-up and surmised the internal shutter was trying to open but wasn't able to. I guessed that the turn off/turn on idea was to resend the command impulse to open the shutter. So.... I t urned it on while repeatedly hitting the side of the lens firmly with the palm of my hand worked!!!!

My camera screen goes white everytime i turn on the camera

I Havee The Same Problem And Ive Been Reading Around And The Most Decent Answer I Found About What Was Wrong Was That Something Had Just Come Loose Inside So That Might Help Because Something Wiring Upo To The Screen Might Be Loose Its Worth A Shot.

Canon Powershot SI screen goes black after taking a photo

That sounds like a sticky lens shutter. They usually have to be replaced, as they usually will need parts. When the camera is working look inside the lens and take a picture(with flash turned off). You should see a black shutter door clicking shut in the lens. When the camera acts up, look inside the lens again. If the door is staying shut full time, that is your problem.

I was in the middle of shooting a wedding, when suddenly my camera said that it was 'busy' - it was taking a while to go back to normal, so I decided to shut the camera off and just turn it back on again...


If the lens does not extend then it is possible that it has become jammed. Sometimes this can cause the camera to sense an error and shut itself down immediately after powering on.
There are other explanations for the behavior, but if the lens does not move this is the most likely cause. If the lens does extend but then the camera shuts right back off it is possible that an inner component such as the focusing element is not functioning properly.

Shutter on k100d

Maybe you can try sensor cleaning mode;
Go to Menu>Set-up>Sensor cleaning, press right than choose "Mirror Up", wait a moment than power off the camera. Maybe this can help.
