The whole computer starts up and the components are all working. But the display won't show anything. As if it has no power in it, please help.

Hello William,

In situations like this it's recommended connecting the PC to an external monitor to see will there be any video signal going out from video output. If it does go out, then there is probably a need for LCD inverter replacement. If there's nothing showing either on external monitor nor display, but the fans are still working, the problem that you have may be due to the failure of the video chip. Sometimes, after much of a use and less cooling the graphics processor, which is responsible for video signal transmission get unsolders, the thermic paste goes away and it gets unsoldered, therefore the screen doesn't show anything. If you have some knowledge of the hardware you can change the paste yourself by opening the PC and check if the chipset that is next to the processor has got unsoldered or you can bring the HP to a technician to get it soldered again.

Please, keep me posted on the issue. Good luck.
