No backlight, potentially shorted capacitor.

I have a MacBook pro 13 inch a1502 with no backlight. After following an online tutorial, the capacitors that are connected to the backlight are all reading 0, or close to 0 when the computer is on.

The tutorials I watched jut replaced the capacitors but didn't specify where they got them, what type, or anything similar.

I do have access to a dead board from an a1502 with a different serial number (the capacitors are in a different place) could I take those capacitors and put them on my existing board? They are the same size and dimensions and seem to be from the same time.

Note: when hooking up to an external monitor, I am not getting anything. However I can see the login screen and mouse when using a flashlight behind the apple logo.

Edit: I am now getting video when connected to external monitor, unsure what caused the problem before. Still no backlight

If you close the lid the external should respond. Or you may have additional problems.

I now have access to external monitor, I’m sure why it didn’t work before. Updated my original issue. Still no backlight, I am leaning towards a LCD cable issue instead of capacitor.

@kolemanpa - Check the logic board connector and display cable for corrosion. More often that’s the root issue and you likely have a blown fuse.
