Sinister lines on my Monitor Screen

My system is an Dell Inspiron 4000 (laptop). OS = Windows XP Home Ed.
There is a sinister green line - thin and vertical - about two inches out from left of display screen. A less pronounced line appears about two inches out from right-hand side of screen. The lines remain irrespective of program. They do not show up when I connect to an external monitor. I replaced the
LCD Flex cables 14.4" 625FR. But the problem remains.
I am curious to know what exactly might cause these lines. I also want to remove them without paying Dell an arm and a leg for a new display. Any advice on this.
