L3341 and L3340 are connected in series on the circuit. The open-circuited condition indicates that the two inductors might have been pseudo soldered or damaged. We need to replace the two damaged inductors with new inductors.

Attach the upper layer to the PCB holder and stick high-temperature tape on components around.

Heat with QUICK 990AD Hot Air Gun at 300℃ and airflow 3.

Remove black adhesive around the two inductors.

Once done, apply some paste flux to the two inductors. Heat with Quick 990AD Hot Air Gun at 360℃ and airflow 3.
