Step 1 Apply grease to the back of Diode (D5702).
Step 2 Fix and screw the Diode (D5702) to the Heatsink A.
Caution: Ensure that Diode (D5702) is properly fixed and 
screwed onto the Switching Regulator Unit.

Step 3 Fix the Switching Regulator Unit onto the SMPS P.C.B..
Caution: Ensure that Switching Regulator Unit is properly 
seated on the SMPS P.C.B..

Step 4 Solder pins of the Switching Regulator IC (IC5701) on
the solder side of SMPS P.C.B..
Step 5 Solder pins of the Diode (D5702) on the solder side of
SMPS P.C.B..
Step 6 Solder pins of the Heatsink A.

• Refer to “Disassembly of Top Cabinet.”.
• Refer to “Disassembly of SMPS P.C.B.”.

 

Step 1 Place the SMPS P.C.B. on an insulated material.
Step 2 Desolder pins of the Diode (D5802) on the solder side of
SMPS P.C.B..

Step 3 Remove 1 screw from the Diode (D5802).
Step 4 Remove the Diode (D5802) from SMPS P.C.B..
Caution: Avoid touching the Heatsink B due to its high 
temperature after prolonged use. Touching it may lead to 
injuries.
Note:  Refer to the diagrams of SMPS P.C.B. (Item 19.4) for
location of the part.

Step 1 Apply grease to the back of Diode (D5802).
Step 2 Fix and screw the Diode (D5802) to the Heatsink B.
Caution: Ensure that Diode (D5802) is properly fixed and 
fully screwed to the Heatsink B.

Step 3 Solder pins of the Diode (D5802) on the solder side of
SMPS P.C.B..

• Refer to “Disassembly of Top Cabinet.”.
• Refer to “Disassembly of SMPS P.C.B.”

Step 1 Place an insulated material under the SMPS P.C.B..
Step 2 Desolder pins of the Diode (D5803) on the solder side of
SMPS P.C.B..

Step 3 Remove 1 screw from the Diode (D5803).
Step 4 Remove the Diode (D5803) from SMPS P.C.B..
Caution: Avoid touching the Heatsink B due to its high 
temperature after prolonged use. Touching it may lead to 
injuries.
Note:  Refer to the diagrams of SMPS P.C.B. (Item 19.4) for
location of the part.

Step 1 Apply grease to the back of Diode (D5803).
Step 2 Fix and screw the Diode (D5803) to the Heatsink B.
Caution: Ensure that Diode (D5803) is properly fixed and 
fully screwed to the Heatsink B.

Step 3 Solder pins of the Diode (D5803) on the solder side of
SMPS P.C.B..

• Refer to “Disassembly of Top Cabinet”.
• Refer to “Replacement of Tray Ornament”.

Caution: If the Digital P.C.B. and/or Mechanism Unit is 
exchanged, the drive adjustment is required because of 
the adjustment data is stored in the Digital P.C.B.. Perform 
the drive adjustment accordance with Section 14 "When 
Replacing the Mechanism Unit and/or Digital P.C.B.".
Step 1 Detach 5P FFC at the connector (P55008) on Digital
P.C.B..
Step 2 Detach 5P FFC at the connector (P55007) on Digital
P.C.B..
Step 3 Detach 45P FFC at the connector (P55001) on Digital
P.C.B..
Step 4 Detach 4P FFC at the connector (P55006) on Digital
P.C.B..

Step 5 Remove 4 screws.

Step 6 Slightly lift up and remove the BD Mechanism Unit
(BRS14P) in the direction of arrow.
Caution: During assembling, ensure that BD Mechanism 
Unit (BRS14P) is properly located and fully inserted on 
Bottom Chassis before screwing.
