9.24. Replacement of Switching Reg-

ulator IC (IC5701)

• Refer to "Disassembly of SMPS P.C.B.". 

9.24.1.

Disassembly of Switching Regula-
tor IC (IC5701)

Caution : Handle the heatsink unit and P.C.B. with caution
due to its high temperature after prolonged use. Touching
it may lead to injuries.

Step 1 : Desolder pins of Switching Regulator IC (IC5701) on
the solder side of SMPS P.C.B..
Step 2 : Desolder pins of Heatsink Unit on the solder side of
SMPS P.C.B..

Step 3 : Remove the Heatsink Unit with the Switching Regula-
tor IC (IC5701).

Step 4 : Remove 1 screw.
Step 5 : Remove the Switching Regulator IC (IC5701).

9.24.2.

Assembly of Switching Regulator
IC (IC5701)

Step 1 : Apply grease to the Heatsink Unit.
Step 2 : Fix & screw the Switching Regulator IC (IC5701) onto
the Heatsink Unit.
Caution : Ensure the Switching Regulator IC (IC5701) is
tightly screwed to the Heatsink Unit.

52

Step 3 : Mount the Switching Regulator IC (IC5701) onto
SMPS P.C.B.
Caution : Ensure the Switching Regulator IC (IC5701) is
seated properly on the SMPS P.C.B..

Step 4 : Solder pins of the Heatsink Unit.
Step 5 : Solder pins of the Switching Regulator IC (IC5701).
Caution : Ensure the Switching Regulator IC (IC5701) is 
seated properly onto the SMPS P.C.B. before soldering.

9.25. Replacement of Voltage Regu-

lator IC (IC2910)

• Refer to "Disassembly of SMPS P.C.B.". 

9.25.1.

Disassembly of Voltage Regulator
IC (IC2910)

Caution : Handle the heatsink unit and P.C.B. with caution
due to its high temperature after prolonged use. Touching
it may lead to injuries.

Step 1 : Desolder pins of Voltage Regulator IC (IC2910) on the
solder side of SMPS P.C.B..
Step 2 : Desolder pins of Heatsink Unit on the solder side of
SMPS P.C.B..

Step 3 : Remove the Heatsink Unit with the Voltage Regulator
IC (IC2910).
