I take out door photos during day time,Iam getting white screen.

First make sure the mode selector dial is set to the red camera without an M next to it (ie you're in Auto mode and NOT in manual mode). If so...

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).

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 the following for further info and a simple fix that may help:

Now the A410 is not capable of taking 15 second exposures as recommended for the fix. Instead try setting the camera to manual mode, turn off the flash, got to a darkened room, and take a picture. Open the battery door while the red and yellow light are flashing. If after many tries this does not work, then consider trying Fix #5a on the site. But do so with the camera turned off and the lens retracted to lessen the chance of damaging the lens mechanism.
