Question about Gateway P-6860FX Notebook
A) Replacement LCD screen backlight could be bad.
Happens. Sometimes you get a bad part. (Bad LCD screen assembly, in this case)
LCD screen may not be the correct one.
A screen Inverter, and an LCD screen; are a MATCHED unit.
B) Screen Inverter:
May be bad, or the Wrong one
C) You may not have the screen Inverter, connected correctly to the Backlight.
Connections aren't tight.
D) The Display Cable TO LCD screen connection may not be tight, or correctly connected.
I know the display shows graphics, but a poor connection of Display Cable to LCD screen, can make the Backlight dim out.
I'm betting it is a poor connection, or the wrong screen Inverter, or wrong LCD screen.
(Be shame to kick that laptop to the curb. Nice laptop)

When the LCD is black and you can see a dim image on the screen then it is a black light problem. could be a faulty inverter but mosr likely a burnt out/worn out CCFL lamp. By connecting and external monitor to the video port, you can determine weather the video card is OK.
If you don't get an image on an external monitor then the video card is faulty and it is impossible to repair except by replacing the motherboard.

Thnak you for your query
You will have to replace the WHOLE inverter board, not just part of it
The inverter is responsible for taking 12V supply and converting the power to a higher volatage to allow the screen to light up
I would suggest that you book the laptop into a reputable PC shop to complete the repair
