If you say that the Display is dim and you can hardly see what is there on the screen. The first thing we need to determine that whether this is a hardware issue or the software issue.

In Order to do the same you need to boot your computer to BIOS(I Mean try to boot to BIOS as you cant see anything on the screen).
If the display is fine in the BIOS than, under the BIOS you will get the options to increase the brightness.


However i am sure you must have done some diagnosis before as it does not seem so simple, because you have mentioned that you have already replaced the LCD and the invertor.

If you do not get a display in the BIOS than it is hardware issue for sure. Now when you have already replace the above mentioned parts, it is most likely the issue on the motherboard.

Most likely you may not find a chip level engineer to repair the motherboard. you would be asked to get the motherboard replaced.

Hence my honest suggestion to you will be that rather than investing more money and time on the same you should take it to the technician who can physically check the laptop.

According to me it would be the best option, however you are the one who is to take the decision.

All the Best.

Hello,

There is a menu in the LCD beside. Did you try increasing the brightness and and contrast of the lcd? however if this not resolve then maybe there some loss connection in the cable and connecting to the pc.

Why is there no display?


hi

can you plug in another monitor to the video plug on the side of your laptop?

if the monitor works but your laptop screen stays dark your laptop screen needs to be replaced .

If the monitor is also dark then the LCD screen is ok but the inverter needs to be replaced

My laptop screen went very dark, I can barely make out whats on the screen but I know its working. What can I do to fix this situation on my gateway p-6860fx pc notebook?


Hi josue fernan...
You need to see if your laptop lcd screen is faulty and/or the lcd inverer is faulty.
1....Test the lcd screen:
Hook your laptop to an outside monitor and then start your laptop normally...if the picture on the external monitor is good, then your lcd screen is bad.
2....Backlight Faulty: If the monitor is still as dark like your lcd screen on the laptop then it could be the backlight that is faulty.
Please take time to rate me thumbs up

The screen on my Toshiba satellite p205 went dark on me i check and u can see the window but really dark i replace the lcd screen and the problem persist help please what can the problem be my video...


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 a faulty inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out; usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

My laptop is very dark and holding fn and the sun


The Back-light on your LCD screen is bad, your crystals aren't illuminating, so it is dark.... very dark.

You need a new LCD screen.

Sorry.

My screen is dark


You could have a defective LCD screen, If the laptop appears to be running and the hard disk is spinning but the screen is dark then, to determine if you have a LCD screen or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering 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 replacing the CCFL lamp.
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 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.

Compaq Presario R3000 dim screen but not dark


Sounds like the auto-dim in the BIOS is set too low. Fortunately the Compaq R3000 allows you to adjust the brightness right from the keyboard. Hold down the [FN] function key while tapping the [F8] key will brighten the screen, while [FN]-[F7] will dim it. The settings are different for running on AC power and battery, so you must do each individually.
