Green Pixelation on lcd display

So I started repair on a mac laptop with a cracked/damaged LCD assembly. It is a A1286 (EMC 2325) from mid 2009, last 3 serial # is 644. The LCD had a few cracks on the glass, plus the bezel for the display assembly was cracked/loose and janky. It displayed things with green pixels throughout. I then checked the external display out and it worked just fine. I figured it was best to replace the LCD and to be safe the lvds cable. After doing so I got the SAME issue as with the other LCD which is green pixelation. I swapped cable, lcd's, old vs. new. All with the same result. I am now slightly baffled. My only thought was maybe the lvds connector was loose on the board. I then resoldered it extremely carefully, cleaned off any excess flux and then gave it a shot of deoxit, STILL same issues. I am just no sure if I am missing something. My only 2 thoughts are the lvds connector is totally damaged or some how the video card is damaged, but only for the internal output and I am not sure if that is possible. Thanks for any help.

Answer this question I have this problem too

Is this a good question?

How did you replace the LCD? Did you replace the complete lid assembly or did you take it apart to replace just the LCD screen alone?


I just replaced the lcd alone. Is there something in the complete lid assembly that helps the LCD color function? I thought all information related to the video comes from the LVDS connector. The other connector I thought was just for bluetooth and wireless, but please correct me if I'm wrong. Thank you so so much.


No I don't think its the lid or anything like that cause this is a loose lcd, although I was just thinking, does the case ground the LCD some necessary way?


So I replaced the LVDS connector on the motherboard and it fixed it!!! I must say it wasn't an easy unsoldering task. For starters the solder just naturally wants to attach itself to the ground plane of the connector, so I found it best to carfefully lift every pin of the connector with a extremely pointy dental pick. Then heat up the ground plane and it comes right off. You can set the new one back into the guides in the board, adding a slight drop of glue in there will also help hold it, so you can solder it down without moving it. Once I did that it was all good. Thanks everyone for your input.


Wow! I'm impressed using a soldering iron with these fine contacts is very difficult. Brian give your self credit here as you answered your own question, mark it answered (resolved).

Is it possible the lid is warped or dented? Causing a short. Is there any dents on the bottom cover as well.
