Having problems with your Princeton Digital VL1812 18.1" Flat Panel LCD Monitor ?

I have a Princeton VL1812 monitor. The screen went black but when I put a flash light up to it I can very faintly see the Windows Welcome screen. So I took it apart to look for the back light or faulty capacitors but unfortunately I can't find the back light and the capacitors look ok. I haven't dissasembled it completely though. Is there anything else I should be looking for? Should I take off the next "layer" which leaves a green film like panel exposed? Perhaps there's a diagram some where on
