In this case check if C302 is assembled. If not, reassemble the component.
If the C302 is assembled, check N300 and surrounding components L300, V300, R300 and R307 for disconnections or
shorts; change or resolder faulty components.
If all above described components are ok, probably D200 UEM is faulty.
