Screen display backlight not working at all.

[dlloydm]

The backlight of my screen is the only thing that doesn't work. If I shine a torch on the screen, I can make out faintly the screen's image however none of it is illuminated by the backlight. The touch screen also works. When I connect my laptop to an external monitor, I can use it, however this means I can't use my laptop as a laptop, as IL am unable to take it anywhere there isnt a monitor. I use my laptop for drawing storyboards at uni, so being unable to use the screen for this is hindering my education and work. If anyone has any solutions or advice for my next course of action towards fixing this issue please let me know.
