Trying to fix my Gateway M275 laptop backlight on the screen.?

Okay so about a week ago my screen went black.I know the laptop is fine..When i run cables to my desktop monitor to my Gateway laptop you can see everything just fine.So i know its something in the laptop screen...I ordered and replaced the LCD inverter board and that didnt work.I notice there is also a" LCD CCFL WITH WIRE HARNESS GATEWAY" on Ebay which if im not mistaken is a light bulb for 20$...should i try replacing this?Or what other things might be the problem?

Ok. We can do this the easy way or the hard way. Since your question seems to be leaning toward the hard way, let's start there.

If you are going to replace the backlight, make sure you have the right tools for the job, and a lot of time and patience. Did I mention time and patience? Most computer repair shops will not even attempt to do this for you because of the amount of time involved. They will simply suggest you purchase a new screen (and with good reason). If you are going to make your purchase and attempt to replace the backlight yourself, all I can say is I wish you the best of luck. I tried this once. It took me about 6 hours, over a 3 day period to successfully complete the job. I would rather set my hair on fire, and try to put it out with gasoline than to try this again.

Now let's go through some troubleshooting steps:

1) Boot up your computer. Take a flashlight and shine it on the screen (at an angle). Can you see your login screen or your Windows desktop (or anything else other than black)? If no? Buy a new screen. If yes? Keep reading.

2) Shut down the computer. Remove the AC power. Remove the Battery. Press and hold the power button for 10 seconds (to ground the system board).

3) Remove your hinge covers (or what ever parts you need to in order to gain access to your inverter board.

4) Unplug all connections from your inverter board, and reseat the connections. Take note to make sure your inverter board is properly connected to the motherboard as well.

5) Replace all parts (including hinge cover, battery and AC adapter).

6) Power on the computer.

7) Find your display close switch. This is a small button usually located somewhere near the laptop hinges. This button turns off the backlight when you close the display of your laptop. If the button got stuck inside, the backlight will not turn on even when the laptop is on and the display is opened. Try tapping on the lid close switch and make sure it moves up and down without any issues.

Shut down the computer. Use a paper clip to hold in the reset switch for 10 seconds. Then reboot your computer.

If none of this works, you are back to square one: Where you either need to replace your backlight or your screen. Good luck. I hope I've helped a little.
