Power failure upon pressing shutter button

First press the DISP or DISPLAY button to see if that corrects the problem. If not, 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.

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.

It's actually a lot easier than you'd think. You don't tell us what kind of camera you've got, but here are some general tips for beginners:

1. make sure the camera has charged batteries in it, and a memory card.
2. find the power button. It's probably on top, near the shutter "take a picture" button. Press and hold it until the camera comes on. It should show you the current 'view' on the screen.
3. If there's a selector dial on the top... turn it to the green one; that's 'easy shooting'.
4. fully press (squeeze) the button. Most kids who moan that 'it didn't take' it's because they only half pressed it. When it takes, the display will show the picture for a few seconds, before going back to the live view.
5. to see your picture, find a button that has the little triangle icon pointing right, like a 'play' button.
6. to go back to taking pictures, press the shutter button again
7. to turn it off, press the power button until it turns off

If that doesn't work for you, tell us what kind of camera you have. That'll make it easier (just a bit!)

put charged batteries try once,if u fail to get image formation then the shutter failure is conformed,get it serviced/replace with a new unit

Try pressing the playback button to turn the camera on. This should turn the camera on just so that you can view any pictures stored on the card or internal memory. You can also access the menu functions this way. Also try pressing the picture/shutter button and see if the lens extends. If the camera shuts off when you press the picture button and the lens does not move or only moves a fraction then the problem is probably to do with the lens

Can you use any of the buttons on the back? A common problem for this model is keypad failure due to the connecting ribbon strip splitting, over time, where it is folded over.
All the buttons on the back of the camera run off the same ribbon. Only the on/off and shutter/zoom button run from a different ribbon.
For the memory problem, this camera has an internal memory but it is very limited and requires an xd card to increase memory capacity. If you cannot use the keypad to view or delete pictures then try either connecting a usb cable to the camera and computer or removing the xd card and use a card reader to view pictures.
If your pictures are stored on the internal memory then obviously you will be unable to view them if your keypad is not working and only by connecting to your pc via a usb lead will you be able to upload and view your pictures. You should also be able to delete them from the camera when plugged into your computer once you have uploaded.

Sounds like you might have accidentally pressed the DISPLAY button on the back of your camera. It turns the screen on and off to save batteries. Turn on your camera, and press this button once again to turn the screen back on.

But if your camera is also taking black pictures,
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, especially when taken outdoors (for shutter stuck open).

You may have just accidentally pressed the DISP or DISPLAY button on the back of your camera. This manually turns the screen on and off to save batteries. You would then use the optical viewfinder in its place. Press the DISP button once with the camera turned on to see if that corrects the problem. If this doesn't correct it...

There are two ways to view the photos, in the camera...

1) if the camera is OFF and the lens barrier is closed, just press the Play (>) button once to view the photos.
2) If the camera is in SHOOTING mode with the lens barrier open, press the Quick View button twice in rapid succession.

When you are done reviewing the pictures, press the Quick View button once to turn the monitor off, OR, to return to the shooting mode, press the shutter button halfway.

Then use the arrow pads to go forward and backward.

Hope this helps.

The cause and solution may include one of the following: The camera is not turned on. Turn on the camera. The camera is processing a picture; the camera Power ring light (on the Mode dial) blinks green. Wait until the light stops blinking before taking another picture. The card or internal memory is full. Transfer pictures to the computer, delete pictures from the camera, switch storage locations, or insert a memory card with available memory. The shutter button was not pressed. Depress the shutter button completely down. There was a failure in the focus and/or exposure. Press the shutter button halfway to set the Auto Focus (AF) and Auto Exposure (AE). When the AF/AE indicator turns green, press the shutter button completely down. The battery is exhausted. Replace or recharge the battery
