LCD screen blank - but external monitor is working

Texto:

I have spent some time on your site, and found similar problems I experience. My iMac screen is black to the naked eye, when plugging in a external monitor it works, and shining a flashligh on the screen reveals that my screen is still working, so my guess is the LED driver portion of the main board is faulty, is there anyway I can fix this?
