Question about HP Computers & Internet

1 Answer

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. I have gone through all of the hp recommendations to check. Is their a backlight lamp or something that I can replace? Iam not familiar with the new ultra bright screens.

From the Windows desktop, hold the fn key and press the f7 key HP Pavillion dv9500t lcd screen - 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.

Did the laptop seem like it boot up all the way? Do you hear the fan running and the hard drive spinning?

If so:
Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.

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 HP Pavilion dv 1000 is too dark. The probem extends 2/3's from the left and almost 1/4 of the screen from the left. It's becoming so bad I barely can read the screen. Thre problem seems to...


If turning up the brightness hasn't helped then the lcd is likely going to fail soon.

option 1: hook it up to an external monitor.
option 2: Look for a replacement lcd on e-bay
option 3: Get a new laptop

HP will charge a lot for the display if they even still stock it.

Hope this helps.

HP Laptop black screen on boot, TV source works


You most likely have a 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.
  • 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.

HP Pavilion dv9500t Vertical Line Issue


try connecting an external monitor to the unit. if you get the same or similar issues on the external monitor then you have a GPU issue on the motherboard. It will need to be REFLOWED or replaced. If you do not get the same issue on your external monitor, then you need to replace your LCD. Our shop replaces these LCDs for 140-180 so i imagine you should be able to find something similar in your area!

Good Luck!

Screen dim to black


This will be a problem with either the screen inverter or screen backlight. You will need to take it to a shop for diagnosis, in order to find out which one it is. If it turns out to be the backlight, then the entire screen will have to be replaced. They are considered a sealed unit, and the backlight can't be changed out.

Laptop screen in complete darkness but external monitor works fine


Make sure to check that it's plugged in on both ends - at the motherboard and on back of the screen.

The other possibility is that your inverter got shorted out somewhere along the way. Try shining a flashlight on the screen - if the cable is plugged in ok you will see a faint imge.
