By whom Kathleen? You?
I ask because there are two ways to answer this;
1) You performed the procedure, and less for me to post.
2) You did not perform the procedure, and I need to explain from the beginning; using a diagnostic flowchart, pictorial guidance, and guidance from me.
While I wait for your reply, suggest perform this simple test first;
Laptop OFF, monitor OFF, attach an external monitor;
1) VGA monitor to RGB (VGA) port on left side of laptop.
Can use a CRT type of monitor (Looks like a small TV), or flat LCD screen monitor if it has a VGA cable.

2) S-Video port on left side of laptop for TV, or external video display device
http://en.wikipedia.org/wiki/S-VideoTurn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By factory default settings, the display should show on the external monitor. (Display device)
If not there are 3 display options available;
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external monitor
3) External monitor ONLY
Press, and hold the Fn key down, and at the SAME time tap once on the F5 key.
The F5 key is the Display Toggle-Over key.
Still no?
Hold the Fn key down again, and tap once more on the F5 key.
Display on external monitor means there is a problem with;
A) Video Cable
B) screen Inverter
C) LCD screen
Which means if computer display was working correctly before;
1) Whoever repaired it could have used the external display option, and it needs to be set back to internal
2) The Video Cable connections are not tight, not correct.
Loose at motherboard, screen Inverter, or LCD screen.
3) Anti-Static Procedures were NOT followed, and laptop is now an expensive paperweight.
