TROUBLE SHOOTING
1. POWER
≧ 0.6V
1.1. The unit does not power on
Does the power indicator on the front panel ash
in green or white when the power is turned on?
Does the power display on the front panel lights
green or white after approximately 8 seconds?
Check the voltage of [CN754 : 5pin] on the DIGITAL
PCB while the power display is ashing in green or
white.
Check the voltage of pins 7 of [CN754] on the
DIGITAL PCB while the power display is ashing in
green or white.
Remove the connector [BN501] of the MAIN PCB.
Check the "3-2. Protection History Display Mode"
The unit does not power on
Is a fuse blown?
Is DC 5.2V being supplied from the SMPS PCB
[BN601] to the DIGITAL PCB?
See "1.2. Fuse is blown"
See "1.2. Fuse is blown"
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 DC5.2V output even when the Board in wire
[BN601] supplying power from the SMPS PCB to
the DIGITAL 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 [CN741] on the DIGITAL
PCB and the microprocessor power supply and
replace any faulty parts.
TO "6. SMPS"
0V 3.3V
0V
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.
