Dell E1405 screen doesn't not light up

Hello folks,

This problem started about 2yrs ago when I cracked my first screen. I replaced with a new one, but doesn't help me a bit. Then last week I replaced both LCD and inverter, guess what not working. I talked to some computer techs, they couldn't give me a satisfactory answer. I wonder if I am missing the direction. If you guys have any idea, let me know.
