Power failure 1: (Normal: High, Failure: Low). Detected voltage failure for analog circuit
[Connected to IC801 pin 52]
Power failure 2: (Normal: Low, Failure: High). Detected
voltage failure for audio AMPP IC. [Connected to IC801 pin 53]
Power failure 3: (Normal: High, Failure: Low). Detected
voltage failure for digital circuit. [Connected to IC801 pin 54]
Temperature Failure : (Normal: Low, Failure: High) Detected temperature failure for Main Power
Unit [Connected to IC801 pin 57]
LED Flashing
When IC801 detects the Power Failure the LED will
flash to indicate a power failure has occurred. The type of failure detected as shown below will determine the
number of flashes. If power failure is
detected 3 times, the set will enter the standby mode, and cannot be switched
ON. To reset the operating programs of
the CPU, it is necessary to disconnect the AC cord for a short time. When finishing the repair or stopping the
Power Failure, the history of past failures can be checked.
TO SEE THE HISTORY
Enter service mode.
Select item number [355] POWER ERROR from the service
adjustment data table.
If simultaneous failures have been detected, the sum of each
data is displayed. For example:
Power failures 1&2
01h + 10h = 11h (17)
After finishing service, reset the data of item No>355
with the < or > keys to ‘00h(0).
