Troubleshooting and error codes

Flow Chart Problem Conditions/Tests Possible Causes/Action
NO.1 Power cannot be turned on. Is the fuse normal? No: See FLOW CHART NO.2
Yes Check for leak or short-circuit on primary circuit components (Q1001, Q1003, T001, D1001-D1004, D1011, C1003, C1005). Check rectifying circuits of secondary circuit.
Is normal state restored when once unplugged power cord is plugged again after several seconds? No: Check for leak or short-circuit on primary circuit components.
Yes
Is the AL+5V line voltage normal? Yes: Check each rectifying circuit of the secondary circuit.
No
Is each voltage of the secondary circuit normal? Yes:
No
NO.2 The fuse blows out. Is there any leak or short-circuit on the primary component? Yes: After servicing, replace the fuse.
No Check for short-circuit on rectifying diode and circuit in each rectifying circuit of the secondary side.
NO.3 When the output voltage fluctuates. Does the photo coupler circuit on the secondary side operate normally? Yes: Check the circuit and replace parts (IC1001, IC1002, D1013).
No
Does the photo coupler circuit on the primary side operate normally? Yes: Check the circuit and replace parts (IC1001, D1012, D1024).
No
NO.4 When buzz sound can be heard in the vicinity of the power circuit. Check for short-circuit on rectifying diode and circuit in each rectifying circuit of the secondary side (D013, D015, D1005, D1008, D1009, D1010, D1016, D1030, IC1041, IC1052, Q051, Q053, Q055, Q056, Q1052, Q1054, Q1055, Q1057).
NO.5 AL-30V is not outputted. Is the voltage of -30V supplied to the anode of D1010? Yes: Check D1010 and their periphery.
No Check for leak or short-circuit on the loaded circuit.
NO.6 PON 44V is not outputted. Is 44V voltage outputted to the emitter of Q053? Yes: Check D013, C013 and their periphery.
No
Is the "L" pulse inputted to the base of Q053? Yes: Replace Q053.
No Is the "H" pulse inputted to the base of Q054? Yes: Replace Q054. No: Replace IC501.
