Laptop inverter freaking out -- URGENT

[AmEv]

My screen is freaking out.

I turn it on, it lights up for a second, then there is buzzing, followed by no backlight on.
Display itself works fine, but without the inverter, I can't see anything.

What would be the safest-cheapest route.


FTOYWDK, it's a Satellite A105-S2231.

Never mind.


In my infinite wisdom, I hooked up the light incorrectly
