Meaning of status indicator display
The power supply unit status indicator shows the status if
an error is detected when the unit is powered on and during
operation.
• If a status indicator does not light when you turn a
POWER switch on, there may be a fault in the power
circuits. Turn the POWER switch off and contact your
Sony service representative.
• When the unit is powered on, the status indicators may
light momentarily in red and a whining sound may be
heard. If POWER A or B only is turned OFF, the power
supply status indicator for that power supply lights in
red. This is not a malfunction. Turn both POWER A and
B switches ON.
