inverter board hard to change?



got an ibook 12" 700mhz dual usb and the screen blanks out when i open it. it only works in certain position and is very touch in what position it works on. i think its the inverter board but i could find nothing on apple but a friend told me about it before and i tried researching and it maybe the culprit. but i was wondering how hard it is to change? and what do i have to open up?
