I recently bought a samsung nv10 digital camera. i;ve only had it for a few months and while i was taking some pictures the other day i noticed that there were lots of little horizontal lines in my picture. Each time a took a picture they multiplied. It got to be so bad that the whole screen would come up white for the quick view of the picture i had just taken. The LCD screen shows a perfectly fine picture untill you press the button to take it. Any one know what's going on? please help.

No idea. My instinct would be to try and reset the camera - perhaps take the batteries out and put them back in again; or, if there's a "restore to factory settings" option in the menu. Failing that, I'd go back to the shop. You're still covered under the manufacturer's warranty...

Best of luck!
