Nikera, this could be caused by the water damage. It is possible that you have a shortened inverter, a shortened LCD or any other part on your logic board. Attach an external monitor and see if that displays anything. If it does, your error is most likely the inverter/display. Download the service manual [http://h10032.www1.hp.com/ctg/Manual/c03575298.pdf|from here] and see if you are up to doing the job. Hope this helps, good luck.
