Whenever i turn on my camera, the lens does not work properly and nothing comes up on the display screen. It then beeps 3 times. When i try and turn it off, the lens retracts but then comes out again so to keep the lens closed i have to take out the battery when its retracted to stop it moving in and out again! HELP! Is this covered on the Olympus warranty, would i be able to get a replacement or my money back?
