Hi guys I am looking for a little advice! So I purchased a MacBook Pro 15” A1286 Mid 2009 which was very beaten up and the backlight didn’t work. The first thing I did was disassemble the laptop, removed the glass (previously done and gorilla glued back on!) and screen and check the LVDS cable. I could see two damaged pins on the cable (logic board side) so I ordered a new one which I tried yesterday. Unfortunately, I still get no backlight which was really disappointing! What are my next steps? I don’t want to buy a new screen assembly if its the connector on the logic board. And I don’t want to replace that connector if its the screen itself! I am pretty much at my budget for this project, having also replaced the keyboard and SSD so I wanted a little advice. What checks can I do to really narrow down the problem once and for all? To add to that, I tested the voltage on the backlight fuse to ground, one side was 12v, the other was nothing. I saw a post that said to bridge it with tweezers to see if the light came on. All I got was a puff of smoke from the board and the fuse blew / blew even more! Everything else seems to be working, still getting LCD working, just no backlight. So now I have a 100% dead fuse, and I’m non the wiser! What can I do?? :( Cheers guys
Not good ;-{ When you over-ride a fuse you run the risk of causing deeper damage, which sounds like what happened. I would see if an external monitor works and you will likely need to find someone with the needed skills to fix your logic board.
