MacBook Pro 13 (820-2879-B) Airport (Wi Fi) not detected

Hi,

Checked L3404 = 5v.
Tested with another similar working screen but still it is not being detected. Any advice?

Regards.

I would check that those 5v arrive at connector J3401 pin 13,14 maybe you have a broken rail

The 5v is present on those pins too.

R3440, R3453, R3454 are well measured and U3440 is fine

All those resistors measured ok with reference to a similar working board, U3440 is what am waiting for from a donor board i purchased.

Thank you.
