Please be sure to confirm and follow these procedures.
1. Product safety
Please conform to product regulations (such as safety and radiation regulations), and maintain a safe servicing environment by
following the safety instructions described in this manual.
1Use specified parts for repair.
Use genuine parts. Be sure to use important parts for safety.
2Do not perform modifications without proper instructions.
Please follow the specified safety methods when modification(addition/change of parts) is required due to interferences such as
radio/TV interference and foreign noise.
3Make sure the soldering of repaired locations is properly performed.
When you solder while repairing, please be sure that there are no cold solder and other debris.
Soldering should be finished with the proper quantity. (Refer to the example)
4Make sure the screws are tightly fastened.
Please be sure that all screws are fastened, and that there are no loose screws.
5Make sure each connectors are correctly inserted.
Please be sure that all connectors are inserted, and that there are no imperfect insertion.
6Make sure the wiring cables are set to their original state.
Please replace the wiring and cables to the original state after repairs.
In addition, be sure that there are no pinched wires, etc.
7Make sure screws and soldering scraps do not remain inside the product.
Please check that neither solder debris nor screws remain inside the product.
8There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord.
Damaged power cords may lead to fire accidents, so please be sure that there are no damages.
If you find a damaged power cord, please exchange it with a suitable one.
9There should be no spark traces or similar marks on the power plug.
When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure
connections and suitable usage. Please exchange the power cord if necessary.
0Safe environment should be secured during servicing.
When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries.
Please pay attention to your surroundings and repair safely.
2. Adjustments
To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification.
Adjustments should be performed in accordance with the procedures/instructions described in this manual.
4. Cleaning
For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper
cleaning should be performed to restore their performances.

Removing the Amp Unit (Fig. 3)
Caution)
The Amp Unit is adhered on the Heat Sink with
silicon grease. This means forcibly removing the
Amp Unit from the Heat Sink may break the
PCB.
Be aware that the RCA Terminal may break
unless the Amp Unit and the Heat Sink are
assem-bled following the correct procedures
given below.
1) Secure the RCA-side Panel on the Heat Sink
with screws. (Fig. 2)
2) Place the Amp Unit on the Heat Sink aligning
with two studs. (Fig. 4)
3) Move the Amp Unit until the RCA Holder on
the Amp Unit comes in contact with the inside
of the Panel. (Fig. 4)
Caution in steps 2) and 3)
When you place the Amp Unit on the Heat Sink,
you will find no positioning marks to determine
the direction of two panels. To position them
correctly, the Amp Unit needs to be moved to
the place where it comes in contact with the
RCA-side panel.
If you do not position them, an excessive force
can be applied to the RCA Terminal. This may
result in breakage.
4) Secure the RCA-side Panel and the RCA
Holder with screws. (Fig. 2)
5) Secure the Amp Unit on the Heat Sink with
screws. (Fig. 3)
6) Secure the Panel for the Power Terminal side
in place with screws. (Fig. 2)

(Since screw threads differ, and screws cannot be used.)
12
Screw holes in the PCB are printed with
numbers 1 to 8.
Remove screws in numerical order.
Re-assembly takes the reverse order of
disassembly.
Remove all of the eight screws. Then,
remove the two black screws (M3 x 5).
Tighten screws whose length is M3 x 8 or
more into the two screw holes so as to
raise the Amp Unit above the Heat Sink.
Then, remove the Amp Unit.
