You may have a defective CCFL backlight, it may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickers on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replace the CCFL lamp.
To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight. It could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out, this is the most likely case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Press and hold the 'FN' key and tap the key that has the picture of a sun and an up arrow (or some other similar picture that dictates brightness - there should be two different keys that affect brightness one to increase and the other to decrease). Once you have the brightness set to your liking quit tapping the 'brightness' key and release the 'fn' key

No backlight


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.

Have you updated a Graphic driver? Does it Dim on battery and AC? Look at power settings. Control Panel, Power. You could Rool-Back the graphic driver to see if that changes the problem. A Gateway mt6841 has Windows XP OS, right?

Have u tried replacing or trying a different power supply? Sometimes when a power supply is going bad will not put out the right voltage for the internal switch to kick up the brighter setting. Therefore it still thinks its on battery mode. Test the voltage from the supply and compare it to the recommended voltage gateway suggest for that laptop.

My Gateway mx7118 lcd flickers whenever screen is opened,closed,


Connect an external monitor to the laptop and power it up, if you see a clear image on an external monitor, this means your video card is OK.

If you see a dim image or flicking image on the laptop's LCD screen it means you have a backlight problem.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

I've also had that, The FN and brightness I've not determined, as I changed LCD panels, however, components in the LCD screen can be swapped out, cable and inverter and backlight (<-very hard to do!!) and the ATI graphics board is mounted to the mainboard, for the C600 they are affordable
