Hello,
I'm working on a dv6000 laptop.
The laptop powers up alright, and the built-in display backlight comes on with a black screem, so I know it's getting power. I've tried a different lcd panel, which didn't fix it and I've tried a new display cable, which also didn't fix it. Same thing, black screen with backlight on.
The laptop outputs to an external monitor just fine. I don't think it's the GPU or motherboard but I can't think of anything else to blame.
I've tried all the other things like unplugging and pressing power button, reseated RAM, reseated CPU, checked connections etc.
It looks like a couple of other people have had the same problem, but never managed to resolve it.
I may try updating BIOS as a last ditch effort.
I was hoping someone on here had a magic fix, key combo or something I could try before I give up.
