<Power supply>
No power supply (Front LED is off) or no power-up (Front LED does not change from red to green)
Is the power supply cord properly connected to the main unit?
Reconnect the power supply cord and turn on the power
Are F1701, F1702, and F1703 normal?
Replace F1701, F1702, and F1703, and then turn on the
power. If a fuse still blows, replace Z1701 , Z1702, D1701,
TRA1701 , D1702, D1703 and D2703.
Is the output voltage of BU+6V Iine (pin 5 of DP terminal)
normal?
In stand-by, is a voltage of about 170 V applied to C3701 ?
Check the oscillation side (primary side) and the
commutation side (secondary side) of the BU5V system
power supply circuit.
Is there any broken part or short-circuit on BU6V Iine?
Remove the broken part or short-circuit and check again.
Are the wire harness, FFC, etc. in the set connected properly?
Reconnect the wire harness, FFC, etc. and check again.
Is a voltage of about 380 V applied to C4701 and C5701 when
power is turned on?
Check the 380V system power supply circuit. (L2701~3,
IC2701~2, Q2701~8, D2701~2, D1704, PC2701, etc.)
Is a voltage of 15 V applied to both inverter lines (INV_15V-1
and INV_15V-2) after power is turned on?
Check the oscillation side (primary side) and the commutation
side (secondary side) of each power supply circuit for the
inverters (INV_15V-1 and INV_15V-2).
Are all power supply circuits for DC/DC converter output
normal?
Check the oscillation side (primary side) and the commutation
side (secondary side) of each power supply circuit for DC/DC
converters
Check or replace DCIDC converters and lines.
URB6V (IC6753)
BS10V (IC6752)

• Power switch: Top panel
(Main) Power (DC cutoff: Detected by microprocessor)
[Scheme of power supply system]
[(Main) Power OFF sequence]
1) (Main) Power OFF (DC switch)
2) (Main) Power shutoff is detected by the monitor microprocessor port
3) Standby request (power cord) is sent to Seine from microprocessor.
4) Seine shutdown process
5) Reception of shutdown permission from Seine
6) Monitor microcomputer turns off the relay to enter the standby mode
