1. Check the area of your repair for unsoldered or poorly-sol-

dered connections. Check the entire board surface for solder

splashes and bridges.

2. Check the interboard wiring to ensure that no wires are

“pinched” or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularly transis-

tors, that were installed during a previous repair. Point them

out to the customer and recommend their replacement.

4. Look for parts which, though functioning, show obvious signs

of deterioration. Point them out to the customer and recom-

mend their replacement.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following

safety checks before releasing the set to the customer.

5. Check the B+ voltage to see it is at the values specified.

6. Flexible Circuit Board Repairing

• Keep the temperature of the soldering iron around 270 ˚C

during repairing.

• Do not touch the soldering iron on the same conductor of

the circuit board (within 3 times).

• Be careful not to apply force on the conductor when sol-

dering or unsoldering.

SERVICE NOTE

1. POWER SUPPLY DURING REPAIRS

In this unit, about 10 seconds after power is supplied (8.4 V) 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.

Method 1.

Connect the servicing remote commander RM-95 (J-6082-053-B)

to the LANC jack, and set the remote commander switch to the

“ADJ” side.

Method 2.

Press the battery switch of the battery terminal using adhesive tape,

etc.

Method 3.

Use the DC IN terminal. (Use the AC power adaptor.)

2. TOTAKE OUT A CASSETTE WHEN NOT EJECT (FORCE EJECT)

1Refer to 2-3 to remove the front panel assembly.

2Refer to 2-5 to remove the cabinet (R) assembly.

3Refer to 2-7 to remove the cabinet (L) assembly.

4Refer to 2-8 to remove the battery panel assembly.

5Disconnect CN4401 of VC-235 board.

6Add +5 V from the DC POWER SUPPLY and unload with a

pressing the cassette lid.

3. NOTE FOR REPAIR

Make sure that the flat cable and flexible board are not cracked of

bent at the terminal.

Do not insert the cable insufficiently nor crookedly.

When remove a connector, don’t pull at wire of connector.

It is possible that a wire is snapped.

Cut and remove the part of gilt

which comes off at the point.

(Be careful or some pieces of

gilt may be left inside)

When installing a connector, don’t press down at wire of connector.

It is possible that a wire is snapped.

4. LCD TYPE CHECK

By measuring the resistor value between Pin 6of CN5502 and

Pin 0of CN5502 on PD-118 board, the type of LCD can be dis-

criminated.

Note: About PD-118 board and LCD module, discriminate LCD

type on the machine, and replace the same type.

SELF-DIAGNOSIS FUNCTION

1. Self-diagnosis Function

When problems occur while the unit is operating, the self-diagno-

sis function starts working, and displays on the viewfinder or Dis-

play window what to do. This function consists of two display;

self-diagnosis display and service mode display.

Details of the self-diagnosis functions are provided in the Instruc-

tion manual.

Note: The “self-diagnosis display”data will be backed up by the coin-type lithium battery (CF-72 board BH001). When this

coin-type lithium battery is disconnected, the “self-diagnosis display”data will be lost by initialization.

2. Self-diagnosis Display

When problems occur while the unit is operating, the counter of

the viewfinder or Display window shows a 4-digit display consist-

ing of an alphabet and 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.

3. Service Mode Display

The service mode display shows up to six self-diagnosis codes shown in the past.

3-1. Display Method

While pressing the “STOP” key, set the switch from OFF to “VTR”, and continue pressing the “STOP” key for 5 seconds continuously.

The service mode will be displayed, and the counter will show the backup No. and the 5-character self-diagnosis codes.

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.)

[1] : Occurred first time [4] : Occurred fourth time

[2] : Occurred second time [5] : Occurred fifth time

[3] : Occurred third time [6] : Occurred the last time

3-3. End of Display

Turning OFF the power supply will end the service mode display.
