If ur notebook have other display output, say, DVI, VGA or HDMI, connect it to other source and single out the problem.
If no other connection or comes up with -ve result, u'll problem need 2 replace some internal cables or even ur LCD panel, which could cost u couple of hundreds or even thousand. Ain't sure ur model or how long u've been using it.
My 2 cents is, if it repair cost u more than a thousand, ain't worth it.
