Motherboard Broken and Replaced but still won't switch on

Speaker had no power, turned out it was a chip on the main board that was faulty. I managed to replace the main board but there is still no power or sound.

A multimeter has confirmed that the main board is now operating correctly and the NFC chip reads.

This is the correct board for the XB5.

Is there something I’m missing, I really don’t understand how it is all connected correctly and there is power through the unit that the power light or any other light won’t light up.

Thanks!
