Hello, The LCD screen on my 13" Macbook was recently cracked by accident and I took it upon myself to order a replacement screen and replace it myself. Following online instructions, I disassembled the laptop and installed the new screen. After attaching the correct connections and replacing most of the screws that attach the screen to the chassis, I checked to see if it was working. It was, everything was beautiful. The only thing left was to re-attach the plastic hinge that covers the inverter. This was a bit tough and it took a number of small prying tools and a bit of time. I was as careful as possible, but after reattaching it and turning on the computer, the screen no longer worked. I assumed that I must have damaged the inverter when reattaching the hinge, so I ordered a replacement. That did not fix the problem. I've plugged the computer into an external display, and that works fine, so there doesn't seem to be anything wrong with the logicboard or its connections. I also tried reconnecting the old, cracked LCD screen (which at had at one time displayed at least a distorted image), but that now displays nothing. I've reset the PRAM and reset the power management by removing the power cord and battery and then holding in the power button. Does anyone know what might be wrong with it and what might be done to solve this problem? Any help would be appreciated. Thanks!
