VOLTAGE OF EACH CONNECTOR
1. How to measure the voltages on the Main Power Supply PCB in protect mode.
• Since a voltage is applied to the Main Power PCB and PFC PCB heat sinks while the set is operating,
do not touch the heat sinks.
• After the power cord plug was pulled out, do not pull out the connector on the Main Power PCB until
the Green LED (D531: Discharge check LED) turns off.
1) Disconnect CN4, CN10, CN41, CN42, CN49 and CN50
2) Connect pins 1 and 2, 3 and 4 of CN4.
3) Press the power button.
2. On the Main Power Supply PCB. (M00BV)
