Voltage Of Each Connector - Fujitsu PlasmaVision P42HHA30WS Service Manual

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 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 CN6, CN23, CN33, CN42 and CN52
2)
Connect pin 1 and pin 13 of CN352 through a 1/4W, 1k resistor.
Connect pin 1 of CN352 and pin 5 of CN509 through a 1/4W, 1k resistor.
CN502 shorted.
3) Press the power button.
