Have you replace the lcd inverter? if it works on external monitor, given the screen is new, then it leaves the inverter. Usually in the case of dark screen, it should be the first thing to check/replace.

SOURCE: I dont know how to replace my HP Pavilion DV100t

Usually you need to take of the panel above the keyboard, it often snaps off, though sometimes there are screws on the bottom of the computer and you have to take off the keyboard too. then you can unscrew the hinges. Depending on what you have to replace you might need to take off the faceplate for the screen by pulling off the little rubber things and unscrewing the screws hidden beneath. If you need any more help just post back.

Laptop powers up but no video


You may have a faulty inverter or defective CCFL lamp. A faulty CCFL lamp 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 and/or 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 or a faulty inverter that supplies high voltage to the CCFL lamp. 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.

If the LCD screen is cracked then the LCD screen needs to be replaced.
If the screen has a backlight problem then the fault could be a faulty inverter that supplies high voltage to the CCFL lamp, or the CCFL lamp is faulty. These items are cheaper to replace than the whole LCD screen.

My laptop screen is flickering


You most likely have a defective inverter that supplies high voltage to CCFL backlight. It is unlikely a faulty CCFL lamp because your laptop is approx 1yr. old.

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 the inverter or 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.
