AC Current Sensor
AC current sensor is used only for LC-XT4E.
The AC Current Sensor is provided to prevent damage to the power supply circuits.
When AC input voltage is under 108V at MAINS SW ON, the AC Current Sensor will be operated and the CPU
does not turn the projector on, and both of READY and WARNING TEMP. indicators start flashing.
Check that the AC current sensor signal is correct. L : Abnormality
