Chosen Solution
Hoping to revive a MacBook with a dead display. To be clear, the computer appears to run ok with an external monitor, but main display is totally black. I tried resetting the display connector and found a blown component - is it a capacitor? What part number should I try to replace it with? Is it worth trying? I’ve soldered a few small components before, but this is pushing it. Main board is 820-3547-A. Thanks for any help!
update: Just adding some pictures of the final solder job here. Pretty horrific, so it’s amazing it works. Sorry pictures are not great, don’t really have a proper microscope or anything, this was using a cheap loupe and my phone. Old blown component still in place:
Desoldered old component, only seeing 2 pads here that are kind of offset, so pretty sure a 4-pad 0806 is not the right component…
New component soldered in, but really it’s just a huge glob of solder, so it’s probably just bypassing the new component:
The blown component is FL8300 , with following specs: 15OHM-100MA-8.5GHZ DLP0NS, but I can’t see it anywhere available for sale on the net. You’ll probably have to find a donor board to get the replacement. BTW, 820-3547 is the I/O board, your logic board is 820-3787-A
