My display started getting a green cast, then died within a day. I sent off for a replacement, and once I got it installed, I found that it still didn’t work. I’m able to hook up an external display and it shows that the computer is working just fine. Should I assume the replacement display is bad? I am reluctant to ask my wife to let me take apart her old MacBook Pro to try hooking up a different display It’s a mid 2012 unibody
This series used LVDS signaling to drive the display which is more analog than what we are working with today with digital. A good way to think this is how our analog TV’s once worked and what we have today with digital TV. With LVDS the pathway the signal travels can’t handle weak connection or signal leakage whereas digital signaling just doesn’t work or offers a strange checkerboard like pattern. There is three areas which can cause LVDS signal distortion like this: The logic board LVDS connector and the pathway to the CPUThe LVDS cable its selfThe Displays LVDS connector and the pathways on the T-CON board As you hadn’t expressed how you went about the display repair it will be hard to dial-in where you need to look or if the replacement part was bad or you damaged something in the replacement process.
