The voltage is supplied by the power-supply through the RF/IF interface usually encased in a metal box on its own. Also without knowing the model number of your unit I cant help any further.

could be your inverter board, whitch controls the backlight. I could very well be the backlight as well, but that is less likely. Inverter boards are not all too expensive, and if you are knoledgable with laptops, i would say doit yourself, but if you have any doubts, take it to apple, sur it will cost more, but it is the safet bet.
