Pavilion DV7 has power, black screen

Question

I came home from a trip. When I went to start up my Pavilion DV7 it had power, but the screen is black. I tried the hard reset, and I also removed the back panels and sprayed with canned air. Still nothing. Lights near caps lock and num lock keys are blinking. I checked the code and it indicates a problem with the CPU. 
Now what the heck do I do?

Answer 1

The following document contains the information of what the blink code means. I take it it is blinking once every 2-3 seconds since you said it correlates to the CPU. The only solution in the document is to contact HP for service.
However, the processor POST code could be triggered by a failed processor or a failed processor socket on the motherboard itself. It can't be identified if it is really the processor or the motherboard without proper testing equipment. You could contact a local PC shop for them to identify the correct component or replace either the processor or the motherboard in hopes it was the right part the first time.
