Working on a dell inspiron e1505, when the machine boots you get flickering, then horizontal lines, followed by color bar like vertical lines. I hooked the machine up to an external monitor and it's working fine. I am assuming that this means there is nothing wrong with the video card or its drivers, does this mean I need to replace the screen.

If it were a driver problem the same thing would happen on the external monitor.
Therefore I would argue that there's an issue with the screen in the laptop which may require a new screen.
