Having problems with your HP PC Desktops ?

My laptop screen is very dark, why? - HP PC Desktops


Answers :

Hi,

Common cause of this problem is either the CCF (cold cathode florescent) lamps or the inverter that powers them is failing or has failed. This would involve opening the display panel casing, exposing the internal and performing further diagnosis. This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

The screen on my HP pavilion dv2736us laptop stopped working completely out of the blue, with no apparent reason. It was working fine otherwise. I came back home after work to turn it on, and it came on (all the lights came on and the HD was 'whirring') - but the screen was pitch black, just like it is when it's off. Any fixes I can try to get it working again?
