LCD or video card broken?

[AllYourBaseAreBelongToUs]

I just put my lcd back in my laptop, and the wires were loose, then it just turned off (maybe I shorted it?). Now it does not work (black screen).

After awhile I was able to get an external monitor working with it.

So I am wondering if it is the video card (built into MB), inverter, LCD display, etc.... that is broken. Any way to tell? I am guessing LCD, but dont want to buy another unless pretty confident. It is a DV6 series laptop from HP

Hi, the problem is probably a coil that is open.

I could only find one other post here that talks about lcd coils.

"Hi, you usually have some protection on the motherboard for such a problem. You should see a burned component near the LCD connector, perhaps a coil."

1. Is this part on the lcd or MB?
2. Regardless of which, is it repairable, or cheaper to buy new part (e.g. $40 for used lcd on ebay).

Thanks jarotech

If it was the video card, then an external monitor wouldn't work either.

If it's a coil that's open, it's on the motherboard near the LCD connector, it's an easy repair, but what's the reason you put your LCD back into your laptop?

Old laptop case fell apart, then bought cheap replacement laptop with same specs, which did not incl a lcd, so I had to swap it.
