Question about HP Computers & Internet
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.
