In this guide I’ll be replacing a failed LCD screen in a Gateway MT3000 series laptop.
To be precise, I am working with a Gateway MT3707 model with failed backlight.
Problem description: It starts with a reddish image and after a few seconds the backlight goes completely off.
Turn it off, unplug the AC adapter and remove the battery.
There are six screws securing the display bezel. These screws hidden under six rubber plugs.
Remove all six plugs with a sharp object.
Remove six screws securing the bezel.
Start separating the bezel from the back cover with your fingers.
On the bottom the bezel is glued to the screen with sticky tape. Carefully separate the bezel.
The inverter mounted on the lower part of the display assembly.
Carefully disconnect the screen backlight cable from the right side of the inverter board.
If you are replacing the inverter board, you’ll have to disconnect one more cable from the other side.
If your backlight problem related to the inverter, you can replace it now and assemble everything back together.
Remove four screws from the left and right hinge mounting brackets (two screws from each side).
Carefully separate the LCD from the cover and place it on the keyboard.
The video cable taped to the back.
Remove the tape securing the cable.
Disconnect the video cable.
Now you can remove the failed LCD screen from the laptop.
You can find a new replacement LCD using the model number. This number is printed on back.
In my case the LCD model number was: LTN141W1-L03.
