Check the area of your repair for unsoldered or poorly-soldered
connections. Check the entire board surface for solder splashes
Check the interboard wiring to ensure that no wires are
"pinched" or contact high-wattage resistors.
Look for unauthorized replacement parts, particularly
transistors, that were installed during a previous repair. Point
them out to the customer and recommend their replacement.
Look for parts which, though functioning, show obvious signs
of deterioration. Point them out to the customer and
recommend their replacement.
Check the B+ voltage to see it is at the values specified.

1. POWER SUPPLY DURING REPAIRS
In this unit, about 25 seconds after power is supplied (8.4V) to the
battery terminal using the service power cord (J-6082-223-A), the
power is shut off so that the unit cannot operate.
This following two methods are available to prevent this. Take note of
which to use during repairs.

the LANC jack, and set the remote commander switch to the "ADJ"
Press the following battery switch using adhesive tape, etc.
2. EJECTING WITH THE CABINET (L) ASSEMBLY
Refer to "2. DISASSEMBLY", and supply power with the cabinet
(L) assembly removed (however leaved the flexible board
connecting the cabinet (L) assembly and CB-58 board connected).
Operate the slider, open the CS assembly (Cassette lid), turn
OFF the CC down switch, and press the Eject button again.

numbers, which blinks at 3.2 Hz. This 5-character display indicates
the "repaired by:", "block" in which the problem occurred, and
"detailed code" of the problem.
C : 3 1 : 1 1
3-2. Switching of Backup No.
By rotating the control dial, past self-diagnosis codes will be shown in order. The backup No. in the  indicates the order in which the problem
occurred. (If the number of problems which occurred is less than 6, only the number of problems which occurred will be shown.)

 : Occurred fourth time
 : Occurred second time
 : Occurred fifth time
 : Occurred third time
 : Occurred the last time
3-3. End of Display
Turning OFF the power supply will end the service mode display.
Note: The self-diagnosis display data will be backed up by the coin-type lithium battery. When this coin-type lithium battery is disconnected,
