Laptop Screen is Black but secondary monitor works fine

marketwizard · May 12, 2014

Hello Everyone;

Any assistance from anyone on this would be greatly appreciated.

Recently, the screen on my HP ENVY dv7 stopped working, so I connected a secondary external monitor to see if it was the video card, but the external monitor works fine. It would seem to me the LCD on the laptop may have somehow become disconnected from the mother board. Is this possible? And if so, what would be the recommended steps to try and fix it?

Thank you in advance.

Well, if it became disconnected the next logical step is to open it up and make sure the screen is still connected.

If you're not comfortable with that, maybe you could send it to HP for repair, especially if it's still under warranty.

I've opened it up but am unable to find where the screen connects to the motherboard.

How far did you go? I find it hard to believe that you couldn't find the connection.

Did you follow the official repair manual (page 92): http://h10032.www1.hp.com/ctg/Manual/c03591253.pdf

Hard to believe? I have no reason to be dishonest. It's likely I didn't go far enough. Hence, I'm on this board asking for advice

Wasn't calling you a liar, for the record.
