Viewfinder Eyecup (ER-E)
The proximity sensor relies on a clear line of sight through the eyecup's cutout. If the eyecup is improperly seated or the integrated transparent window is occluded by skin oils or debris, the IR signal reflects prematurely, locking the camera into EVF-only mode. Replacing the eyecup restores the intended optical path for the sensor's infrared beam.

Electronic Viewfinder (EVF) Unit
The proximity sensor is a discrete optoelectronic component integrated into the EVF assembly. A hardware failure occurs when the IR photodiode loses sensitivity or the logic board fails to register the voltage drop across the sensor's output pin. As the sensor is rarely serviced as a standalone SMD component, replacing the EVF unit is the required resolution for a confirmed electronic failure.

Main Circuit Board Assembly
The signal from the proximity sensor is processed by the camera's image processor to manage power distribution to the displays. If the sensor and its ribbon cable are intact, the failure may reside in the logic gate responsible for the display switching interrupt, necessitating a replacement of the primary PCB.
