Carefully separate the two halves of the case. Light prying may be required. If you examine the second photo you can see one of the plastic retaining tabs on the front of the top half. A pick or similar tool prove helpful without marring the case.
Remove the three Phillips PH000 screws circled in orange; The PCB can then be removed for inspection and repair.
