Broken Lense

My VPC-E760 Sanyo camera is a little over 4 mo. old. It was dropped about the 2 mo. i had it. Then lense popped back ito place, but it makes a funny noise when turning on and off. (or going in and out when previewing pics). Last night, it was working fine then turned off, said 'lense error 25' 'lense error 22' and 'lense error 12'. I don't know why! I tried to find out what it meant, but i couldn't SOMEONE HELP!!!
