Here is the rundown. I will try to be thorough as possible.
I got in a Dell Inspiron 1525 laptop that when you use just battery power it worked fine. When it was plugged in the screen went dark (visible to flashlight).
I suspected it went dark when plugged in because of the power management settings turning the brightness all the way up when plugged in and dimmer when not.
I turned on the laptop with battery power, used the FN+arrow keys to brighten the LCD and sure enough it went dark when it hit the top brightness.
I tested the laptop with an external monitor and it worked fine.
I replaced the inverter. This resulted in the screen being dark no matter what the power settings were.
I then got a new LCD and replaced it (along with another inverter), again dark no matter the power settings. I tested the LCD in another laptop (inspiron 6000 the store said it was compatible). This resulted in a dark screen as well. I called the store and got a replacement shipped out to me.
I received the replacement screen and the exact same thing has happened including when tested on the other laptop.
My last thought is to replace the LCD ribbon cable though I think that may be grasping at straws since it did not work in either laptop.
I have installed the original inverter and screen back into the laptop but can not get it to go back to it's original issue. The screen is dark no matter what.
Am I looking over something?
