Hp Pavilion Black Screen

Hi all,

ok got a Dv9000 which sometimes works fine and other times just shows a blank screen but you can see there is some light if that makes sense, kinda grey looking, hd seems to be loading windows as light if flickering like normal.

I have tried holding down power button with no joy, is this the famouse HP motherboard problem ?

It may be the back light going out on the screen.  There is a small compact fluorescent light bulb and power inverter inside the bottom of the screen that often goes out in laptops.  Try plugging in an external monitor to the VGA port on the laptop and see if the motherboard is still functional.  If it does work with an external monitor you can search on google or ebay for a Dv9000 replacement screen.  I have replace many laptop screens this way.

If you're more comfortable with taking apart the screen, you can just replace the compact fluorescent light bulb and power inverter for a lot less than replacing the entire screen.  Those can be a little more hit and miss with the quality though and some require soldering.

Hope this helps.

Use a torch light to see if you can see the images on the screen. Likely that the inverter or CCFL is faulty as explained by C3.

Changing the CCFL is cheaper but needs patience and experience. Its much easier to change the entire LCD but it will cost you much more.

You can also take a look at the manual at http://h10032.www1.hp.com/ctg/Manual/c01311536.pdf
yes - you have the famous HP bad video series problem.
there is a recall program : http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01087277&lc=en&cc=us&dlc=en&product=1842189&lang=en

if you want to fix it yourself, you should reflow the video chip
