Several hardware problems can be causing this behaviour.

The first two items I check is the Cable that goes from the screen to the motherboard and the video inverter. Both repairs are relatively inexpensive.  At worst it will be the video card on the motherboard but that doesn't seem to be the case since the external monitor works.
