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 per-
sonal 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, certifica-
tion or 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.

WARNING: CHEMICAL CONTENT NOTICE!
The solder used in the manufacturing process except soldering of the P.C.B. ass'y 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 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 REA-
SON 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 main unit are soldered using the all lead free 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)

As the melting point temperature of the lead free solder is about 30C to 40C (50F to 70F) higher than that of the lead
solder, be sure to use a soldering iron suitable to each solder.

Starting DIAG
Press the "STANDBY/ON" key while simultaneously pressing those two keys of the main unit as indicated in the figure
below.

Keys of main unit




Turn on the power while pressing these keys.




Starting DIAG in the protection cancel mode
If the protection function works and causes hindrance to trouble diagnosis, cancel the protection function as 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 pressing 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 FACTORY PRESET of DIAG menu No.3 (Memory initialization inhibited or
Memory initialized).
* In order to keep the user memory stored, be sure to select PRESET INHIBITED (Memory initialization inhibited).
2 Turn off the power by pressing the "STANDBY/ON" key of the main unit.




Display provided when DIAG started
On the FL display of the main unit, an opening message (including the version and the protection history) appears for a few
seconds followed by the diagnostic menu display (1. FIRMWARE VERSION).


When there is no history of protection function:

RX-E810/RX-E410/NX-E800


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 a defect or overload in the power supply. If the power
P1 PRT:000 A
is turned on with the abnormality unsolved, the protection function works in about 3 sec-
onds to turn off the power.
P3 PRT:000 A


The protection function worked due to the temperature limit being exceeded. Causes could
TM PRT:000 A
be poor ventilation or a defect related to the thermal sensor. If the power is turned on with
the abnormality unsolved, the protection function works in about 3 seconds to turn off the
power.

For detection of each protection function, refer to DIAG MENU No.4 AD DATA.

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 previously 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
initialized) of DIAG menu No.3 or when the backup data is erased.




Operation procedure of DIAG menu and SUB-MENU
There are 9 MENU items, each of which has some SUB-MENU items.

DIAG menu selection
Main unit: Select the menu using the "B"(Forward) and "N"(Reverse) keys of PRESET/TUNING.

SUB-MENU selection
Main unit: Select the sub-menu using "PRESET/BAND" (Forward) Key and "AUTO/MAN'L" (Reverse) key.

1. FIRMWARE VERSION
The firmware version, model, destination and checksum are displayed.
The checksum is obtained by adding the data at every 16 bits for each program area and expressing the result as a 4-figure
hexadecimal data.

* Numeric values in the figure example are for reference.

This program is used to check the FL display section.
The display condition varies as shown below according to the sub-menu operation.

Segment conditions of the FL driver and the FL tube are checked by turning ON and OFF all segments. Next, the operation
of the FL driver is checked by using the dimmer control. Then a short between segments next to each other is checked by
turning ON and OFF all segments alternately (in lattice). (In the above example, the segments in the second row from the top
are shorted.)

3. FACTORY PRESET
This menu is used to reserve/inhibit initialization of the backup RAM (Set menu contents, etc. of the sound field program).

PRESET INHIBIT (Initialization inhibited)
3.PRESET INHI
RAM initialization is not executed. Select this sub-menu to protect the values set by the user.
Note: The protection history will not be erased using PRESET INHIBIT.

PRESET RESERVED (Initialization reserved)
3.PRESET RSRV
Initialization of the back-up RAM is reserved. (Actually, initialization is executed the next time that
the power is turned on.) Select this sub-menu to reset to the original factory settings or to reset
the RAM. Use PRESET RESERVED to erase the protection history.

CAUTION: Before setting to the PRESET RESERVED, write down the existing preset memory.
Content of the Tuner in a table as shown below. (This is because setting to the PRESET RESERVED will cause
ALL user memory contents to be erased.)

4. AD DATA CHECK
This menu is used to display the A/D conversion value of the Microprocessor which detects panel keys of the main unit and
protection functions in using the sub-menu.
When K0/K1 menu is selected, keys become non-operable due to detection of the values of all keys. However, it is possible
to advance to the next sub-menu by turning the INPUT of the main unit.

P1: Detects +5I, B and AC2.
P2: Detects +5I, 12, +10V, -VP and AC1. P1:xxx P2:xxx
* If Px is out of the normal value range, the protection function works to turn off the power.
(Reference voltage: 5V=500)

P3/TH (Power supply voltage protection detection/Temperature detection)
P3: Amp DC protection (Normal value: 0 to 402)
* If Px is out of the normal value range, the protection function works to turn off the power.
(Reference voltage: 5V=500)
TH: Detects the temperature of the heat sink. P3:xxx TH:xxx
