Inspiron 1545

Our Inspiron 1545 was dropped. There is now a vertical white stripe with a few black lines about a third of the way from the left side of the screen. To the left and right the screen appears normal but is a split screen with partial images on both sides. When hooked up to an external monitor that monitor displays normal. On the laptop the screen to the left of the white/black bars is still visible. The right side goes blank like it does when hoooked to an external monitor.

Question - new LCD screen or does something else need to be replaced?

Thanks in advance.
