The dim display could be caused by a faulty inverter. The inverter supplies high voltage to the CCFL lamp that provides the back light to the LCD screen.

If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp.

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.

Gateway laptop screen darkens after boot up


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?

Hello !

Since an external monitor works, it is the display's backlight or inverter board.

If you were experiencing discoloration in the screen (pinkish lower light hues) before it failed, that would indicate a CCFL backlight issue. If the screen suddenly went dim on you rather than a slow degradation the inverter would be indicated.

In either case, a technician in your area should be able to help. Evaluate to see if the repair is cost-effective.

Hope this helps.

Gateway 450sx4 has very dim lcd, almost invisible. otherwise it (the computer) is ok


Hello and thank you for using Fixya's services.

I have a couple of questions and some troubleshooting tips for you:

Questions: Is the splash screen coming on at all? Any picture or text right when you boot up? What Windows are you running (Windows XP or Vista)? Are there any lights on when you boot up or beeps? If so how many beeps do you hear?

First troubleshooting: If it boots up and is at least showing the splash screen (Gateway splash screen or text) then it would be that the operating system is corrupt. This can be caused by several things included viruses, power surges or hardware failure.

The solution for this would be to take the hard drive out and slave it to another working desktop computer to retrieve your data. The attach the hard drive back on and reformat it (I can add specifics to doing this once I know the operating system).

Second troubleshooting: If you hear the operating system chime but do not see a picture and all the lights are on, then this would indicate that the back light on the screen is out. You can test this simply by hooking the laptop up to a monitor and see if you get a picture. If the computer screen shows on the monitor, then your back-light is out. If it doesn't show up then your video graphics card is out.

If the back light is out, it is easier to order a new screen (new or used) from eBay and just switch out (simple process and you can find a replacement for under 50 dollars on eBay). If it is the video graphics card, then you can also purchase one from eBay and switch out (a little tougher because you have to take the top of the laptop off). You can get assistance with this from the manufacturers website and pull specs for free.

Third troubleshooting: If you do not hear any beeps and the above solutions did not work. Then your motherboard has failed. This can be caused by surges or dust. You can purchase a replacement from eBay for a fraction of the cost and replace (this is tough and I am not sure if they have specs for this). You can do it yourself, just be sure and put everything back together as it was.

Fourth troubleshooting: To test the battery, take the battery out of the laptop and turn on with just the adaptor. If it boots, then the battery will need to be replaced. There is no way of testing the power adaptor but 85% of the time, this is the problem. Even if lights come on, the adaptor sometimes gets so overheated that it silently goes out but gives just enough power to make the lights come on. The power adaptor can be found on eBay for under 20 dollars and is cheap enough to replace (first) to make sure that is not the problem. The battery can also be found on eBay for under 60 dollars.

Please let me know if you have any questions and I will be glad to assist.

Check the video connectors on the motherboard.
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.

Booting


Has the fan been replaced? If not then the laptop will power itself off to protect from overheating. The fan is like a switch in the loop. Like old Xmas lights. One not working then none will work.

Dim screen


If its very dark and you can barely see anything its probably a bad back-light. I'd suggest to take it to your local Best Buy. And yes, they can look up PSP#'s with your credit card, but even easier by telephone number.
