It is either the inverter board or the bulb

If it looks pink in color than it is the bulb and that can be quite the intensive project to replace

If it is the inverter board than that is not so bad and you can pick up an inverter board on eBay usually for around $10 to $20 and that usually installs right under the LCD screen (usually screwed to the LCD screen)

The inverter board is what powers the light bulb the data cable is totally separate function.
If you can see data on the screen with a flashlight but there is absolutely no light coming from the screen at all ever than it is probably just the inverter board

But there is a possibility that you could order the inverter board and have it turn out to be the bulb and if that is the case then unless you are very comfortable taking apart laptops then maybe a new screen would be best since you practically have to take apart the LCD to change the bulb.

But screen cost around 100 to 150 on eBay so if you decide to do that then might as well try for a deal like this: (I just spotted this on eBay and it is for entire new top half of laptop with glossy screen and inverter board wire harness and all for the same price or less than just the screen http://cgi.ebay.com/HP-dv1000-Pavilion-14-1-BrightView-Glossy-LCD-screen_W0QQitemZ310102538774QQihZ021QQcategoryZ31569QQssPageNameZWD1VQQrdZ1QQcmdZViewItem#ebayphotohosting

That is guaranteed to solve your problem for sure.

Laptop screen is very dim. There is a very faint image. The LCD screen is brand new so that's not the problem


Hello,

As per your description, it is probably your inverter which is faulty.

The inverter is an electrical device which 'lits' the LCD. Without the inverter and the bulbs it powers, the screen would be too faint to be seen correctly.

To test if the inverter is defective, just turn on your laptop in a dark space, then put a flashlight on the screen to see if you have a fainted display. If you can see something, it is the inverter which is defective and should be replaced.

If you are handy, you can also remove the screen cover to see if there is a neon like light which lits up behind the LCD. If you can see the light, it means that the inverter is just working fine and that the is with the LCD itself, but if there is no light coming from behind the LCD, then you need to replace the inverter.

Replacing the inverter:

1. After removing the screen 'cover', locate a small circuit board (usually below the LCD). Unplug the electrical cables and replace.

Hope this posts helps you.

My hp laptop turns on bt the screen will not come on how can i fix it


Hello,

As per your description, there are two possible causes. Either the LCD is out of order and needs to be replaced, or that the inverter is defective.

The inverter is a electrical device which 'lits' the LCD. Without the inverter and the bulbs it powers, the screen would be too faint to be seen.

To test if the inverter is defective, just turn on your laptop in a dark space, then put a flashlight on the screen to see if you have a fainted display. If you can see something, it is the inverter which is defective and should be replaced.

In case the inverter is working correctly, try to check the LCD cables. If all cables are well connected, your LCD has to be replaced.

IBM Thinkpad R51, screen went dark. At the right screen angle, I can see some light from the windows and cursor, but very faint. At that light angle I can maneuver the mouse and click on windows, so all...


The problem
1 The LCD screen is out or
2 The invertor board behind the LCD screen is out or
3 The backlite is out

You have 2 options
1 To use an external monitor for the time or
2 get the laptop fixed by a tech shop

Black screen on booting my Compaq 610 notebook


If it seems like you're accessing the hard drive (drive light comes on, flickers intermittently, then goes off, it's a good chance your screen is bad.

First thing to do is plug in an external monitor and start up the laptop. If it comes up with windows, you know it's the screen.

To find out if it's the backlight, or the lcd, toggle the monitor function and shine a flashlight on a slight angle to the screen. If you can faintly see what was displayed on the external monitor, then the backlight inverter is probably bad.

If the external monitor didn't come up, you're probably looking at a motherboard.

The good thing is that all of those are covered for one year under Compaq's warranty, on a new machine.

If you are able to use the external monitor, back up your data, because HP/Compaq usually reformat the harddrive. Additionally, if you've added memory, pull the cards. They want it sent back the way it came from the factory.

Screen is blank but I can see a faint display of the desktop on my ze4220 laptop


Try reseating your lcd cable. It runs from behind the lcd and goes to the motherboard. If you reseat it and you still have the faint screen then its going to be either a problem with the LCD or a problem with the inverter which provides the voltage to the LCD.
