Display fix with capacitor?

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!

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

Thanks for the fast response! I’ll look around and see what I can find... anybody else know of an equivalent replacement component?

The filter is like a fuse and wire. But it is designed to have a higher resistance at radio frequecnies. This allows it to block interference. It’s unlikely you’d notice much if you use a different filter at the same rated current,but it’s best to get the right component. You can use the schematics and Paul Daniels software to help you find component data.

Remember,a filter is kind of like a wire. But it does act like a fuse since it’s rated for low current. It can blow and protect the circuit if there’s a short. If you replace it with a wire,it is potentially at a higher risk.
