Does the power indicator on the front panel ash
in green or white when the power is turned on?
Is a fuse blown?
Does the power display on the front panel lights
green after approximately 10 seconds?
Check the voltage of [N1019 : 1 - 6pin] on the
DIGITAL PCB while the power display is ashing in
green or white.
Remove the connector [CP4001] of the SPEAKER PCB.
Check the "3-2. Protection History Display Mode"
The unit does not power on

Check the circuits around the Microprocessor on
the DIGITAL PCB and replace any faulty parts.
TO "3-2. Protection History
Display Mode"
Are there any parts not fully connected into the
connectors that connect the PCBs?
Is DC5V output even when the connector [N1033]
supplying power from the SMPS PCB to the DIGI-
TAL PCB is removed?
Check the circuits around the Microproces-
sor on the DIGITAL PCB and replace any faulty
parts.
Check for breakages and short circuits in the cir-
cuits and parts between [N1033] on the DIGITAL
PCB and the microprocessor power supply and
replace any faulty parts.
Connect the connectors correctly.
TO "6. SMPS"
Check for leaks and short circuits
in the parts on the primary side.
Replace any faulty parts.
Blown fuse
Check the rectier diode in the
rectier circuit on the secondary
side, and check for short circuits.
Replace any faulty parts.
Replace the fuse after repair.
Check for short circuits between the
regulator output terminal and GND
in the power supply stabilization
circuit. Replace faulty parts if there
is a short circuit.
