What's wrong when your fingernails have lines?

Whats wrong if there's vertical lines on the lcd screen/hesitates the picture while viewing?

• when i go take a picture i see vertical lines on the lcd screen. I point and shoot and take the picture. well when the picture appears on the screen it is grey and black(looks like a negative) at first with little lines in it and then the screen will start to clear up slowly. it wasn't doing that 4 days ago when i last used it. I've changed the battery in it and it is still doing it. i'm assuming it has to do with the lcd screen. i hooked it up to the computer to make sure the picture comes out right. there are no lines on the pictures and the picture is in focus so i don't know what's going on. I know someone else handled the camera when i wasn't around, could it have been dropped or bumped for the screen to be acting this way?

• Answer:

  Sounds like a fault, just with the LCD. Best get it checked.
