1.

Check the area of your repair for unsoldered or poorly-soldered
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
transistors, that were installed during a previous repair.  Point
them out to the customer and recommend their replacement.

4.

Look for parts which, through functioning, show obvious signs
of deterioration.  Point them out to the customer and
recommend their replacement.

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 soldering

or unsoldering.

After correcting the original service problem, perform the following

safety checks before releasing the set to the customer.

Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size.)

Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40

°

C higher than

ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350

°

C.

Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!

• Strong viscosity

Unleaded solder is more viscous (sticky, less prone to flow) than
ordinary solder so use caution not to let solder bridges occur such
as on IC pins, etc.

• Usable with ordinary solder

It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

CAUTION

Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type.

In this unit, about 10 seconds after power is supplied to the battery terminal using the regulated power supply (8.4V), the power is shut off so
that the unit cannot operate.
These following method is available to prevent this.

Use the AC power adaptor (AC-L200/L200B).

1

Refer to “2. DISASSEMBLY” to remove the mechanism deck block.

2

Supply +4.5V from the DC power supply to the loading motor and unload with a pressing the cassette compartment.

It is possible to turn on power by adjustment remote commander (RM-95 or NEW LANC JIG).
Operate the VTR function using the adjustment remote commander.

1) Select page: 0, address: 01, and set data:01.
2) Select page: A, address: 10, set data:01 and press the “PAUSE (Write)” button of the adjustment remote commander.

1) Select page: 0, address: 01, and set data:01.
2) Select page: A, address: 10, set data:02 and press the “PAUSE (Write)” button of the adjustment remote commander.

1) Select page: 0, address: 01, and set data:01.
2) Select page: A, address: 10, set data:00 and press the “PAUSE (Write)” button of the adjustment remote commander.
3) Select page: 0, address: 01, and set data: 00.

When problems occur while the unit is operating, the self-diagnosis
function starts working, and displays on the viewfinder or LCD
screen what to do.
Details of the self-diagnosis functions are provided in the Instruction
manual.

When problems occur while the unit is operating, the counter of the
viewfinder or LCD screen shows a 4-digit display consisting 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.
