Hello!
- Use a continuity tester to check, if the pin(s) that are not connected to the ground are connected to any pin of the MPS OFN chip located under the missing component (on another side of the board). If so, specify to which pin(s) exactly.
- Your pictures are not very clear. If I see correctly, one pin of the missing component located next to the WiFi card is connected to the pin 16 of this QFN chip. Can you confirm this?
- Use a continuity tester to check, if any pin of the missing component is connected to the ground.
