Hi, I recently replaced the screen for my MacBook (A1181) after I dropped it and the display panel cracked. Shortly after doing so, my screen would go negative when the display would be moved or adjusted; however,I noticed that the display will return to its typical color if I apply constant pressure to the top left corner of the display. I know this is not a graphics card issue as I have connected it to other monitors and I do not experience the same problem when doing so. So basically, what I am asking is what part, if necessary, needs to be replaced? Furthermore, I believe it may be the screen, as I was cheap and bought a used one and I am asking this question just to make sure. Thanks in Advance.
Theres nothing particularly interesting in the upper left corner of the MAcbook besides the Airport Antennae, so I would have to say you were sold a faulty display.
I know this is an old post but I am also experiencing some similar issues to my macbook. I want to know if I need to replace the whole LCD or if I can replace an Inverter or a different display component. I have some photos of the broken mac next to a fully functional mac.
