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.

Why does screen go black after a few seconds


Hope this helps.... Your monitor has an inverter issue. You know it's an inverter problem when:
1. Your monitor starts normally and displays the startup/desktop screen for a while.
2. Then it suddenly goes off, leaving a blank (black) screen or a very dim display.

To fix this black screen problem, change the inverter board (based on your monitor brand).

Now my screen says gateway very dim and goes black


The screen on your laptop computer is the primary graphical interface that allows you to interact with your Gateway laptop computer. The screen is connected to your computer through video cables located within the base of the laptop. If your laptop will boot up but the screen remains black, it is likely the video or power cable on your Gateway laptop has somehow become disconnected. Reconnecting laptop hardware is a very difficult operation and is not recommended for anyone that is not familiar with computer hardware.

Remove the faceplate of your old laptop by removing the plastic hinges located on the sides of the base. The hinges can usually be removed with your fingers. Open the latches that secure the keyboard to your laptop. Some laptops use screws to secure the keyboard; remove these if necessary and unplug the connector. If you are having trouble finding the screws on your laptop, they are normally located near the corners. Unscrew the screws that connect your laptop screen to its base. The screws will be located near the bottom of the screen's base. Reconnect the video cable and power cord that connect your screen to your laptop and make sure they are firmly connected. Reassemble your laptop to complete the operation.

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?

My g60 -235dx laptop on startup error message say communication problem with I/O deveice, HD, flash drave , CD-ROM


G60-235dx. (2011 model, is my guess)
ok tell the full story please.
PC boots sequentially.
progress in that matters. so it seem windows unstated runs?
XP?
so you power on and what happens ?,
errors before windows logs in or after.?

my guess #1 is the main laptop battery is bad, remove it.
this pC runs on AC power pack endlessly, (AC power good)
dim screens. can be bad CCFL lamps or low power in the PC.
so again take out the battery
what flash drive, remove that, test the pC with no usb devices at all plugged in.

just an A.C power pack and no main big battery.
this PC has old CCFL lamp tubes that all go dim, fast.
turn yellow then dim the flicker and then DIE for ever.
all do. some in 2 years time never turned off. they do.

it the screen goes black use a flashlight if data is good on the screen the back lamp is croaking. (***** of CCFL tubes)
there are many cause of black screens, I can list 30. (will not)
but dim screens are only
1; main battery bad and shorted.
2: AC power pack near dead. (weak happens)
3: shorts in the main board, modules.overloading power buses.
4: CCFL dim as every one this old does, all do.
see flash light test.

The screen goes very dark within a minute after booting up = I can just barely see the menu page


When you say screen goes very dark when it booted to windows so it means that when you turned on the laptop when the dell logo flashes the screen was fine? if thats the case could you please try this. after turning on the laptop you will see the dell logo flashes immediately keep tapping on F2 and then it will show you the BIOS setup utility, please check if in BIOS setup display goes dark as well. If yes then try this, after turning on the computer when dell logo flashes keep tapping on F12 to boot menu then select utility partition to run the diagnostics. Please run test on the LCD check if display goes black when running the LCD test. Then try this when you sees the dell logo keep tapping on F8 to boot in safe mode check if in safe mode display goes very dark. Try this too, boot in F8 then select last known good configuration check if the settings on your display will be fix. If you can boot to safe mode no problem then uninstall the display or video driver. then restart computer.
You can also try to connect an external monitor if you have one just try to isolate if issue is on the LCD or the video card. If the display is dark as well in external monitor then video card needs to be reseated if fails then replaced. In situation like this most video cards is integrated to the motherboards. So replace motherboard.

Power stays on but screen goes black on my Gateway laptop.


If the laptop appears to boot up and the hard disk LED flashes then you have a backlight problem.

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 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.

Dell inspiron 6400 display goes off < 1 min after switch on time


Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

If you see a very dim image or black screen or flicking image on the LCD screen it means you have a backlight problem.

The buzzing sound is most likely the inverter 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.

IBM T40 Laptop screen goes black, will not come back


First of all, you have to check whether you can see video signal with surrounding light tilting the screen.
If you can see dim image, all you have to do is replace back-light inverter or fix it. Usually, the fuse is open and you can connect it by simple soldering.
If you can't see dim image, it is another problems.
Give it a try.

This problem may occur due to wrong driver of display card or wrong display settings.
Solution:
1- Start you computer in safe mode.
2- Remove display card driver.
3- Restart you computer.
4- Install display card driver (if it does not pick automatically).

Now it should show default settings. I hope it would solve your problem.
