Chosen Solution
Hello. I have a MacBook A1342 K84 Unibody. i want to change the connector, because i saw that one pin was broken. But i don’t know for what the pin is. It is the 14 or 17 pin, depending on from which side you look. I think its the + pin for the backlight. And the fuse seems also be death, slightly to the left from the connector. And the damaged pin have a destroyed solder point. So i want to check where i can solder a cable to this pin to bring back the backlight. can i solder directly to the fuse? At least, im not really sure, why the damage happens. Maybe water.. But its the only one problem. so what should or can i do? Regards
Sven, according to your serial number your computer is a MacBook “Core 2 Duo” 2.26 13" (Uni/Late 09) 2.26 GHz Core 2 Duo (P7550) Intro Date: October 20, 2009 Disc Date: May 18, 2010 Order No: MC207LL/A Model No: A1342 (EMC 2350*) Subfamily: Late 2009 Model ID: MacBook6,1 Std RAM: 2 GB Std VRAM: 256 MB Std Storage: 250 GB (5400 RPM) Std Optical: 8X DL “SuperDrive” The connector in question is J9000 and it is your LVDS connector. The Apple part number for it is 518S0650. Not likely that Apple will get it for you so here is what it is. It is an I-Pex Board to Board Connector 20474-030E-11 It does have thirty contact points and two grounding points. In your computers case there are two grounds per point. Pin 1 through 18 are LVDS contacts, pin 19 through 26 are backlight contacts and 27 through 30 are for the camera. The fuse you marked is F9800 which is a 2amp 32 V SMC fuse in a 0402 package. the other part you are linking to is reference designator T3902 and it is a TLA-6T213HF pulse transformer. Since we now identified the parts, we can try to assist with the placement of jumpers, which will be extremely difficult. If you ever want to replace the LVDS connector so you can plug your display etc. back in you will have make 100% sure that you cleared all short circuits on the traces. Your image is not the best to see if there are any crosswired traces. The image attached shows the wiring schematic of your logic board. Based on this you could try to outline where to run any jumpers. You could also try and attach a few better images of the logic board with the surrounding area so that we may try to assist you with it. the image you have right now is just not sufficient to identify each contact and where the contact goe3s. BTW soldering 30 points on a logic board and running jumper wires would be a very advanced skill which will require good tools and excellent skills. Let us know if you are up to it and post some images to see if we can further assist you. Hope this helps, good luck.
UPDATE here is an updated image to show you where pin 14 and 15 connect to. I also outlined the fuse. The contacts you circled in your image must be separated.
Further Update Here you can see how the contacts look like.
