SERVICE MANUAL


IMPORTANT NOTICE
This manual has been provided for the use of authorized YAMAHA Retailers and their service personnel.
It has been assumed that basic service procedures inherent to the industry, and more specifically YAMAHA Products, are already
known and understood by the users, and have therefore not been restated.
WARNING: Failure to follow appropriate service and safety procedures when servicing this product may result in personal
injury, destruction of expensive components, and failure of the product to perform as specified. For these reasons,
we advise all YAMAHA product owners that any service required should be performed by an authorized YAMAHA
Retailer or the appointed service representative.

IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute authorization, certification or




RX-V657/HTR-5860
recognition of any applicable technical capabilities, or establish a principle-agent relationship of any form.
The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineering, and service
departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitable and
specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, please contact the
distributor's Service Division.
WARNING: Static discharges can destroy expensive components. Discharge any static electricity your body may have
accumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to this buss).
IMPORTANT: Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.

1. Critical Components Information WALL EQUIPMENT TESTER OR
Components having special characteristics are marked Z OUTLET UNDER TEST EQUIVALENT
and must be replaced with parts having specifications equal
to those originally installed.

2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated INSULATING
from supply circuits. TABLE

q Meter impedance should be equivalent to 1500 ohms shunted q Leakage current must not exceed 0.5mA.
by 0.15µF.
q Be sure to test for leakage with the AC plug in both
polarities.

WARNING: CHEMICAL CONTENT NOTICE!
RX-V757/DSP-AX757/DSP-AX757SE




The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or
plastic (where applicable) components may also contain traces of chemicals found by the California Health and
RX-V657/HTR-5860




Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm.

DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR
ANY REASON WHATSOEVER!

Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes
or expose eyes to solder/flux vapor!

If you come in contact with solder or components located inside the enclosure of this product, wash your hands
before handling food.


About Lead Free Solder /
The P.C.B.s installed in this unit are soldered using the fol-
lowing solder.

Among some types of lead free solder currently available, it
is recommended to use one of the following types for the
repair work.
· Sn + Ag + Cu (tin + silver + copper)
· Sn + Cu (tin + copper)
· Sn + Zn + Bi (tin + zinc + bismuth)
Caution:
1. As the melting point temperature of the lead free solder is
about 30°C to 40°C (50°F to 70°F) higher than that of the
lead solder, be sure to use a soldering iron suitable to
each solder.
2. If lead solder must be used, be sure to remove lead-free
solder from each terminal section of the parts to be re-
placed and from the area around it completely before sol-
dering, or make sure that the lead free solder and lead
solder melt together fully.

When checking the P.C.B.:
· Reconnect all cables (connectors) that have been disconnected.
· When connecting the flat cable, use care for the polarity.
· The P.C.B. removed from the chassis does not work because
its grounding is loose. Be sure to connect the ground of each
P.C.B. to the chassis or GND with a jumper wire or the like.
