Blue led, no boot, system shut-down

I’m looking for a little advice. I have a New 3DS LL I picked up for pretty cheap, knowing it wasn’t fully functional. Unit shuts off after a few seconds of blue light. It isn’t necessarily making the popping sounds which might indicate a faulty speaker ribbon cable. Since there are too many variables to rule out, not knowing if it’s one or multiple components, I decided to put this board into a known working unit.

In the first picture, you can see the four seated ribbon cable (indicated by numbers 1. through 4.), along with the ABXY daughterboard (not photographed) to allow my fully functioning board to get me to a boot screen. After disconnecting the good board and swapping it with the faulty board, symptoms still remain. This leads me to believe that there is something wrong on the board itself.

I’m wondering if anyone might be able to offer a little advice on how to test the sockets/capacitor/circuitry found in the second image (indicated by red rectangle). Does anyone know what these capacitor readings should be when testing with a multimeter? When I compare them to the know working motherboard, they are certainly different.

In the third image, a close up is taken of the same indicated area of the faulty board from the second photo, which there appears to be a discolored capacitor (indicated by magenta arrow), second from the top.

Logic tells me that if even (1) capacitor near these (4) sockets is faulty, this would cause a no boot situation, correct?
