Question about HP Pavilion dv4000 Notebook

1 Answer

Hp pavilion dv4000 screen is dark and unreadable

The screen on my laptop is working, but the lamps that make it readable are not. This occurred after my roommate used my hp printer power supply on my laptop instead of my laptop power supply. The printer power supply is 31 volts output, the laptop output 18.5 volts. The screen has been dark ever since. What can I do to fix this? I'm real poor. But if I knew what part to purchase I could fix this myself. Help.

    I am having a similar problem. My screen is fine when I first start up and after coming back from screen saver, but it just goes out about 15 times a day. If I press the Sleep button, it lights back up but then goes to sleep. Sometimes when I do that, it comes back.

    Very frustrating.

    Any advice?

    Thank you.

Monitor keeps shutting off after a few seconds- hp dv4000notebook


You may 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 or appear black. 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 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 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.

Dv4000 hp pavilion dark screen


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.

Dark unreadable screen


If you see a dim image or flicking image on the LCD screen it means you have a backlight problem.
Connect an external monitor to the laptop and power it up, if you see a clear image on an external monitor, this means your video card is OK.

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.

When starting my DV4000 - the screen is dark other than a cursor in the left corner.


That error indicates a hard drive problem. You probably have to replace the hard drive.
