do some googling, IIRC the dv2xxx laptops were recalled for cracking joints on the onboard gpu.
try connecting a regular moniter to the vga out, it that works then the gpu (and mobo) is fine, and you probably blew out the inverter for the screen, with is cheap and simple to replace (so long as you dont mind ebay and laptop labor). if this fails, then, with out the laptop in hand, that the mobo is shot, and trust me, not worth the effort of replacing for that line of HP's.
