Awhile back this MBP 17" Hi-Res was dropped on the upper left corner. After that the backlight no longer functioned properly. I first tried replacing the inverter board which didn't help. I finally got around to replacing the whole screen today. Fired the thing up. Display looked great. It worked for about an hour before I heard a weird noise from the computer and the backlight went out again.

Any thoughts?
 
I just found out that the replacement screen is actually a different part number than the original LG screen. Is it possible that the new screen is incompatible with the factory inverter board? Could this incompatibility have blown out the backlight? Maybe the screen assembly was just bad out of the box....:(
