I have a Gateway laptop 450 which is no longer under warranty and recently the LCD has just gone dark. I have connected it to a monitor and received no problems with the display there, and I can see the screen faintly on the LCD.
I have tried the brightness and contrast buttons on the keyboard, but got nothing from that.

I have already opened the laptop, but honestly have no idea in what direction I should be looking.
Is this a hopeless case?

Any help would be awesome!!

I decided that I'm going to do it myself. I've already taken the whole laptop apart and taken the LCD screen out. Believe you me, it IS NOT for the faint of heart!

Taking apart the LCD screen itself is an exercise in nerve conditioning. I found a website where I can purchase the lamp replacement, but have to get the lamps out to find out the correct part number.

Once I'm done, I will post my methods, part number replacement and the lamp manufacturer.

Wish me luck!

RE:Gateway Laptop 450 Dark Screen

This is a common problem with the Gateway 450 Series Laptop.
If you screen is just dark and external monitor works fine. 90% of the time the problem is going to be the Inverter Unit and not the back light bulb.
The inverter unit is what powers the back light, ie turns on the light.
If you need more help or need the inverter unit, give me a call.
I would be more the happy to help.
