Question about HP Computers & Internet
My laptop HP Pavilion entertainment PC's screen has just gone black whilst I waas working on it. It is still turned on at the power outlet and power light is still on, I aslo tried my friends pavilion ac power cord and not change. Is there a button on the computer that I may have hit that hides the screen. Do you have any other suggestions
You could have a backlight problem.
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.
