It sounds like a short or loose connection. If you're very savvy, you could fix it your left. However, frankly, if you were you would be coming to us. I'l suggest taking it is for services.

My compaq presario cq40 is power on but no display in screen.. the caps lock and num lock light is blinking...

Please get and test your Display chipset this causes that problem as you walkthrough the steps of how BIOS works. It stops from the execution of the program written to test the functionality of the output which is your DISPLAY or LCD screen or PRN.

This might cost you around RM200 bucks.
