it can fixed only camera fixera company,better if you fix it according to camera company because your problem also be facced to me,i take it to a ordinary camera fixer and then my camera fully get damaged because who fixed my camera they fall acid in battery placce.

i could be that the rechargeable batter is weak. try replaceing the battery for a new one. also check that the connections for the battery are clearn.

I hope this was useful.

is sounds like you have the shutter set on bulb.. try changing the shutter speed and see if this helps....

Not sure if you mean the automatic lens cover, or the actual lens shutter, so here's fixes for both:
Stuck automatic lens cover
Stuck shutter

Thanks for the additional information.

Remove the lens and set the camera to manual exposure mode. Select the "B" (or "Bulb") shutter speed. Open or even remove the camera back and hold the camera up to a light source and press and hold the shutter. Look through the camera to see whether there is any horizontal obstruction towards the bottom of the film gate ( = top of negative, they're taken upside down). If you see an obstruction then assess the damage and if it's a foreign body then remove it. Note that you must absolutely not reach through the open shutter. If it closes whilst you have your fingers or tools in the way you will ruin the shutter assembly.

If that test shows nothing, then you really have run out of options and need to send the camera to a service centre for diagnosis and repair. It's likely to be a sticking shutter causing an overexposed band across the negative, usually the width of the band would show some variation in width and position depending upon shutter speed.

A poor battery will not be the cause of a shutter issue. Unless faulty, the shutter will either work or it won't, unlike the previous F3 the F4 lacks a mechanical back-up shutter speed.

A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, sometimes with lines, especially when taken outdoors (for shutter stuck open). To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help. Recommend trying the pencil tapping fix listed in the link. It worked on my SD1000 with the same problem.

By the way, my wife happens to own a SD1000. Great little camera, but it's prone to stuck shutter every once and a while. Easily fixed each time though by simply opening the battery door while on, and gently flicking the lens barrel a few times. Again, see the link.

So I assume you have changed the batteries and made sure there isn't any corrosion on the contacts. If your mirror is flipping up but no shutter, it sounds like a bad shutter. Check the shutter from the back, then from the front behind the mirror. Look for abnormalities or residue. It is a great camera and uses standard batteries (!) but the 1/2000 shutter has a half life like any other SLR. If you are going to throw it out you may want to open the back and use a q-tip to drip a couple drops of 90% alcohol on the top and bottom (and sides) of the shutter. As a last ditch, I throw cameras or lenses in the toaster oven at 200° for 10 min. and retry (take out batteries and film). At the least it will kill any fungus at the worst it hardens some lubricants. It does make you feel like you are doing some specilized scientific work before you toss it in the trash.

Lines across your pictures or pictures too bright are due to the shutter not closing correctly or at all.
to check this- turn camera on, turn off flash, turn camera around and look into the lens. Adjust the zoom so that the shutter and internal lens comes up to the end of the lens and whatch as you take a picture. You should see the shutter close completely over the lens. If it doesn't move or does not close over completely then there is your problem.
If camera was dropped it could have jammed the shutter open or obstructed it in some way from closing completely.
camera will require repair/ service.
You may have some luck if you power up and down your camera numerous times before taking a picture. The action of the lens opening and closing may free the shutter.

Have the electronic shutter checked by a repair shop. Sounds like your Seiko electronic shutter has died or there's a short somewhere between shutter and lens. Hope this helps.
