[Solved] How to fix black screen on HP DV7 laptop?

By Kelby232 ·

I have a problem with my HP DV7 laptop. I keep getting a black screen and I am having trouble fixing it. The beep code I am getting suggests it is a CPU issue. The beep code is just one flash every few seconds.

Here are the steps I have taken to try and resolve this. First, i've tried toggling the monitor. Second, I've tried connecting it to an external monitor and still did not get a picture on either screen. Then, I removed the battery and held the power button down for a minute to discharge any static electricity. I then started the laptop up without the battery in. Still not getting a picture. Finally, I've tried reseating the processor. (just lifting the processor up and replacing it.) I still did not get a picture. After every step I kept getting the 1 flash beep code.

So what are my next steps to take? Should I invest in a new CPU or is there something else I am missing?

Thank you in advance.
