I have an HP Pavilion DV7 with a LED LCD screen and the screen is black upon power up. If I use a flashlight to shine on the lcd when the laptop is booting I can see the win7 desktop and cursor. I have not connected it to an external monitor but I think it would work. If this were an older style LCD I would believe the inverter had died and I have replaced many of those. But this is an LED style LCD. Is there anything that can be done or is the whole display going to need changing?
Thanks in advance.
Did you get your DV7 screen working? I have same problem. I tried replacing screen but no luck. I am now attempting to replace the display data cable.
