Sl300 dim


If it is an LCD, there is a back light. That is usually fluorescent so there is an inverter. If it is an LED display, there is no back light as such so no inverter.
All the service manual recommends is to change the DC-DC converter board, followed by the System Board, if that doesn't work the complete display unit.

Why is my Gateway 4028GZ screen black


The display on this laptop is backlit. What that means, in a nutshell, is that the image on the display prevents the output from a constant light source (the back light) from showing through, thus giving a usable image on the screen. From your description, the backlight is no longer operating. This can be an issue with the LCD display panel, the backlight power module, our (less likely) a power trace on the motherboard. Repair would likely cost as much or more than replacing with a used laptop and just transferring your hard drive. If you choose to replace and swap hard drives make certain that the interface on the new laptop is the same as your Gateway's.

The LCD screen on my Gateway M-6317 is dim. How


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

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.

Cant see anything diplayed on my computer MT3422


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 very dim image or flicking image on the 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.

Dell inspiron 4150 video dim


The empty slot is for a mini-PC card, usually a wireless network card. The 2 wires are actually the antenna wires that connect to the wireless card. The dim LCD may be a problem with the LCD panel display, video controller or motherboard. Try connecting the laptop to an external monitor by connecting to the Video Connector located on the back of the laptop. If the display on the external monitor appears to be normal, then your LCD display panel on the laptop has a problem. If the display on the external monitor is dim then you probably have a bad video controller card or motherboard.

LCD goes dim within 1-2 minutes


You could have a bad "inverter" or flourescent backlight tube, or a problem in your power supply.The only way to isolate the problem is to check each component in sequence.If your hard disk and DVD / CD drive are still working when your screen goes dark, then I'd say it's the "inverter". You'll have to take it to a repair shop.
