(D5702)
9.23.1.
Disassembly of Rectifier Diode
(D5702)
• Follow (Step 1) to (Step 3) of Item 9.3.
• Follow (Step 1) to (Step 11) of Item 9.6.
• Follow (Step 11) to (Step12) of Item 9.13.
• Follow (Step 1) to (Step 9) of Item 9.20.
Step 1 Desolder pins of the rectifier diode (D5702) on the sol-
der side of SMPS P.C.B.
Step 2 Desolder pins of the heatsink unit B.
Step 3 Remove 1 screw from the switching regulator IC
(IC5701).
Step 4 Remove the heatsink unit B with rectifier diode (D5702)
in the direction of arrows.
Step 5 Remove 1 screw from the rectifier diode. (D5702).
Step 6 Remove the rectifier diode (D5702) from the heatsink
unit B.
Caution: Handle the heatsink unit B with caution 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 18.5) for
location of the electrical components.
9.23.2.
