HP G71 laptop, replaced the screen and cable and the image isn't right, works fine with VGA

A customer brought in a HP G71 laptop with a broken screen. They had tried to replace the screen and after that when you turned it on there was no image but it seemed to get brighter the longer the laptop stayed on. Then we ordered a replacement screen and the same thing happened. After that we replaced the cable (since the old cable looked like it was torn out of the LCD.)
After that we replaced the screen again, this time ordering the exact screen that came with the laptop (the other two screens were third party screens with a little cable to plug into the LCD cable since the connection was on the opposite side of the LCD on the third party models.) That gave us an image but it looked like the image on the cracked screen (without the crack.) The image is shifted over to the right and up, there's a big white bar on the bottom, and the top of the image is displaying on the bottom.
I would have assumed the graphics chipset was no good but the VGA output works perfectly fine. Does anyone else know what's going on with this thing? I've run out of ideas of what to check.
