Do you have another screen attached? This will cause this trouble. If not, if you look closely at the screen, can you see an image? You might be able to shine a light into the screen and see an image. If so, sounds like the inverter is or has died. Try tapping the bottom plastic on the screen when the laptop is on and see if it flickers. If it does perhaps it is a loose connection/solder joint on the inverter board.

Laptop screen goes dark.


Is your computer setup to go to sleep when you close the lid?

Click on start -->control panel-->power options and then check the option that says choose what closing the lid does. You have to change this setting to 'do nothing' if you want the computer to stay on when you close the lid.

Presario R3000 display went dark can not see Screen goes black after a few minutes of use. You can see a very faint image after a few seconds, but you must do a soft re-start to bring the screen back....


Defective CCFL backlight may has 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.
  • 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 it up, 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.

HP Pavillion dv9500t lcd screen is extremly dark. I can barely see anything once it is booted up. I can hook up an external monitor and the laptop functions properly with exception of the laptop screen....


From the Windows desktop, hold the fn key and press the f7 key c00776226.jpg to increase or the f8 key c00776225.jpg to decrease the brightness of the display. If using the function keys does not resolve the problem and you have a Lid Actuator on your particular model, check the movement of the Lid Actuator switch to determine that it moves freely and is not stuck. NOTE: The key numbers ( f7 or f8 ) may vary depending on the notebook PC; however, the images on the keys should be familiar. Check the movement of the Lid Actuator switch The Lid Actuator switch is available on some models. It is a small button or switch located above the keyboard near the hinge for the LCD. Pressing this switch when the computer is on may turn the notebook display off, or it may cause the notebook to enter a different power state. Press the switch two to three times while observing the display. If the display does not return to normal brightness when the switch is released, the switch may be sticking and need to be repaired. Contact HP service and support for further assistance. If the display turns off when the switch is pressed, the power management function may be set to hibernate or turn off when the lid is closed. Install updated BIOS and drivers To resolve certain hardware and software issues, use HP Health Check to automatically search the HP web site for an updated BIOS as well as any updated software and drivers. To launch HP Health Check, follow the steps below.
  1. Click Start , type health into the search field, and then select HP Health Check from the list. HP Health Check displays a list of available BIOS, software, and driver updates for your particular model.
  2. Click the description link for any BIOS, software, or driver updates, and then follow the on-screen instructions. You can only install one update at a time.
  3. Repeat steps 1 and 2 above for all updates that you want to install.
You have now installed the available BIOS, software, and driver updates for your particular computer model.

Compaq r3000 dark screen


If you already replaced the inverter and the screen still continues dark, you need to replace your lcd screen. Your video card is good due you have signal with external monitor.
