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.

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.

● Starting DIAG
Press the “STANDBY/ON” key of the main unit while simul-
taneously pressing the “INPUT MODE” key and the “MULTI
CH INPUT” key to activate the DIAG function.

Turn on the power while pressing these keys.

● Starting DIAG in the protection cancel

mode
If the protection function works and causing hindrance
RX-V757/DSP-AX757/DSP-AX757SE

to trouble diagnosis, cancel the protection function as

RX-V657/HTR-5860

described below and it will be possible to enter the

DIAG mode. (The protection functions other than the
excess current detect function will be disabled.)
Press the “STANDBY/ON” key while simultaneously press-
ing those two keys indicated in the figure above. At this time,
keep pressing those two keys for 3 seconds or longer.
In this mode, the “SLEEP” segment of the FL display of the
main unit flashes to indicate that the mode is DIAG mode
with the protection functions disabled.

CAUTION!
Using this product with the protection function disabled
may cause damage to itself. Use special care for this point
when using this mode.

● Canceling DIAG
1 Before canceling DIAG, execute setting for PRESET of 1
DIAG menu No.9 (Memory initialization inhibited or
Memory initialized).
* In order to keep the user memory stored, be sure to se-
lect PRESET INHIBITED (Memory initialization inhibited).
Protection history will remain in memory. 2
2 Turn off the power by pressing the “STANDBY/ON” key of
the main unit.

Version (1 alphabet)

When there is a history of protection function:

The FL display appears as shown below depending on the
type of the protection function.

The protection function worked due to exces-

sive current through the amplifier. Causes
I PROTECT Z
could be a short at the speaker terminal or a
defect in the amplifier. The protection func-
tion activates immediately to turn off the
power, with no history display at turn-on, if
the amplifier is defective.

The protection function worked due to a de-

fect or overload in the power supply. If the
PS PRT :000 Z
power is turned on with the abnormality un-
solved, the protection function works in about
1 second to turn off the power.

The protection function worked due to a DC

voltage appearing at the speaker terminal.
DC PRT :000 Z
A cause could be a defect in the amplifier. If
the power is turned on with the abnormality
unsolved, the protection function works in
about 3 seconds to turn off the power.

The protection function worked due to the

temperature limit being exceeded. Causes
TMP PRT:000 Z
could be poor ventillation or a defect related
to the thermal sensor. If the power is turned
on with the abnormality unsolved, the pro-
tection function works in about 1 second to
RX-V757/DSP-AX757/DSP-AX757SE

turn off the power.

RX-V657/HTR-5860

For detection of each protection function (except I-PROTECT)

, refer to DIAG MENU No.10 AD DATA (p.42).

● History of protection function

When the protection function has worked, its history is stored
in memory with a backup. Even if no abnormality is noted while
servicing the unit, an abnormality which has occurred previ-
ously can be defined as long as the backup data has been
stored.
The history of the protection function is cleared when DIAG is
cancelled by selecting PRESET RESERVED (Memory initial-
ized) of DIAG menu No.9 or when the backup data is erased.

● Display during menu operation

During the DIAG operation, the menu list described in
the section of the startup screen appears on the monitor
screen and the function at work is indicated on the FL
indicator. The contents displayed during the function op-
eration are described later in the “Details of DIAG menu”
section.

■ AMP ADJUSTMENT

● CONFIRMATION OF IDLING CURRENT ●

1. Immediately after the power is turned on, measure the
voltage across resistor terminals in the column “A” in the
table below and confirm that the measured value is be-
tween 0.1mV and 10.0mV.
2. If the measured voltage exceeds 10.0mV, open (cutoff)
the resistor in the column “B” in the table below and re-
confirm the voltage.
Attention:
If the idling current exceeds 10.0mV after a power ampli-
fier repair, check for a defective component before cut-
ting the resistor.
3. Confirm that the voltage is between 0.2mV and 15.0mV
after 60 minutes.
