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.

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.

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.

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.

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

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

Refer to 2-8 to remove the front panel assembly.

2

Refer to 2-10 to remove the cabinet (L) assembly.

3

Refer to 2-11 to remove the cabinet (R) assembly.

4

Refer to 2-16 to remove the battery panel assembly.
