CAPACITOR ELECTRICAL DISCHARGE PROCESSING
When removing the SMPS board and MOTHERBOARD board, be sure to perform the discharge process by referring below procedure.
Remove SMPS board first follow by MOTHERBOARD board.
Note:
Be sure to discharge using a resistor of 500~800
Ω
.
SMPS Board (Conductor side view)
1. Disconnect all the wires and FFC which connected to the SMPS board (avoid touching any component).
2. Unscrew the SMPS board.
3. Pulling up the wire (avoid touching any component) to lift up the SMPS board.
4. Flip the SMPS board to conductor side and perform discharge at terminal of C6302, C6558 and C6559 for 10 seconds each.
MOTHERBOARD Board (Conductor side view)
1. Disconnect all the wires and FFC which connected to the MOTHERBOARD board (avoid touching any component).
2. Unscrew the MOTHERBOARD board.
3. Holding the both edge (avoid touching any component) to lift up the MOTHERBOARD board.
4. Flip the MOTHERBOARD board to conductor side and perform discharge at terminal of C2076 for 90 seconds.
