I have the following issue:
My Video LCD Cable is broken (Some of the little cables inside are broken) and i need to replace it. But i'm not sure if the Inverter is also broken. Is there a way to know that so i can buy both of them or only the LCD Cable?

If i only connect the inverter to the LCD, should there be a blank white screen at least?

How do i know I only need to buy those two parts (Inverter and LCD Cable) and it's not also my video card in the logic board that got burned?

When i turn on the computer, i get no video at all, no blank white screen or anything. I know it boots and loads the OS since i get some sounds at boot.

Thanks for any tips i received!

The Powerbook is a 17" 1.67MHZ.
