Check for short-circuiting or leak on the load circuit,
and service it if defective.
FLOW CHART NO.1
The power cannot be turned on.
Is the fuse (F1001) normal?
Is normal state restored when once unplugged power
cord is plugged again after several seconds?
Is the AL+5V line voltage normal?
Check each rectifying circuit of secondary circuit and
service it if defective.
See FLOW CHART No.2 <The fuse blows out.>
Check for leak or short-circuiting of primary circuit
component and service it if defective.
SYS+5V (IC1051, IC1052, IC1151, D1051, D1052,

Yes
Yes
Yes
No
No
No
Is the SYS+5V line voltage normal?
Yes
No
FLOW CHART NO.2
The fuse blows out.
After servicing, replace the fuse (F1001).
Check the presence that the primary component is
leaking or shorted and service it if defective.
Check the presence that the rectifying diode or circuit
is shorted in each rectifying circuit of secondary side
and service it if defective.
FLOW CHART NO.3
When the output voltage fluctuates.
No
Yes

normally?
Check the circuit and service it if defective. (IC1001,
D1025, D1022, D1023)
Check the circuit and service it if defective.
(IC1001, IC1101, D1102)
FLOW CHART NO.4
When buzz sound can be heard in the vicinity of power circuit.
Check if there is short circuit on the rectifying diode and the circuit in each rectifying circuit of secondary side, and
service it if defective. (D013, D014, D016, D018, D019, D1031, D1032, D1033, D1034, D1035, D1101, D1103, IC1103,
IC1104, Q1100, Q1102, Q1106, Q1108, Q1112, Q1119, Q1508, Q1511, Q1513, Q1516, Q1517, Q1520, Q1521, Q1527)
No
Yes
FLOW CHART NO.5
-FL is not outputted.
Is the supply voltage of -36V fed to the anode of D018?
Check D018, D020 and their periphery, and service it
if defective.
