Photo has 'lines' across it. New batteries just fitted. Have the settings been reset??? How do I get rid of the lines???

I have white lines going vertical on a third of my screen on the left side?

Lines across photo's or over exposure Is due to the shutter not closing correctly. Common cause for this is moisture fouling the shutter leafs. It only has to be a very tiny amount to cause an obstruction. If you turn on your camera and turn the flash off face the lens towards you and look at the lens in the middle you should be able to see the shutter fire across the lens when you take a picture. I know its small but you should be able to spot if there is a gap ( may not be very big) where the shutter leafs meet. What you need to do is remove the lens unit from the camera, dis engage the zoom motor ( the motor nearest the front lens) then remove the main lens to access the zoom lens and remove that aswell. Behind it is the shutter. Undo the screws for the retaining plate, remove the plate, and then remove the shutter leafs for cleanning with lens cleaner or anything that will clean without leaving a residue. And remember not to touch the leafs after cleaning, use tweezers.
