Ok. Lets verify if this is problem with the graphics adapter or the screen itself. Do you hear the system start up? If yes then are you able to get a display on external monitor and press the display swap key? Please provide this info so that we can continue the diagnosis

My HP Pavillion keyboard lights up but the screen is blank what can i do?


Press num lock key of key board if num lock led is on/off then your cpu gives display to monitor Then make sure monitor cable is connected properly to cpu vga port.
When you power up the cpu press F8 key then enter in "enable vga mode" Then go to start->control panel->display->settings.
Change screen resolution to 1024*768 then apply and ok.
Then check.
But if num lock led is not on/off and left constant then you need to open cpu cabinet.
Refix RAM memory.Pull cmos cell from motherboard for 10 minutes.
Clean dust from all parts.
Reattach processor and it's fan.
Make sure motherboard is not ground with cabinet.
Open motherboard from cabinet and try outside of cabinet.
Let me know if you need further assistance.
Thanks for using FixYa.
