SERVICE MANUAL

A unique identification number (Unique ID) is given to each unit, which is imprinted on the CD mechanism assembly. If and when the mechanism assembly or Flash ROM (IC17) on the mechanism board is replaced, it is necessary to write the Unique ID. For details, refer to “How to Write the Unique ID” on Page 18.

TEST MODE

KDC-MP828/W7531/W7531Y/W8531

/W8531Y/X789/X8529/X889

● How to enter the test mode

In order to enter the test mode, reset the unit while simulta-

neously pressing down [1] and [3] keys.

● How to clear the test mode

The test mode is cleared in case of any of the following events:

resetting, momentary power down, Acc OFF, Power OFF and

removal of the panel.

● Initial conditions of the test mode

• Source is STANDBY.

• Displays lights are all turned on.

• The volume is at –10dB (The display is 30).

• Loudness (LOUD) is OFF.

• CRSC is OFF, regardless of whether there are switching

functions or not.

• SYSTEM Q is NATURAL (=FLAT).

• BEEP will sound anytime with a less than 1 second push.

• Auxiliary (AUX) is ON.

• DISPLAY TYPE is TYPE D.

• The Multi-function Key System are source dependent sys-

tems. (TUNER → Preset, CD / CD-CH → Scan, etc.)

• Display of TUNER sources will be as follows :

European Models : Upper Display=PS/frequency, Middle

Display=spectrum analyzer, Lower Display=multi-function

Other Models : Upper Display=SNPS, Middle Display =spec-

trum analyzer, Lower Display=multi-function

• CD source display will be as follows :

All Models : Upper Display=P-TIME, Middle Display= spec-

trum analyzer, Lower Display=multi-function

• SWPRE is SUB WOOFER.

● RDS automatic measurement

Conventionally, the PS display has been visually checked on

the production line. This will be replaced by a new processing.

The PS data will be received and the PS contents is to be

verified as “RDS_TEST”. When this is verified, the P-CON

terminal is forced to go OFF. (In this case, “ _ ” means blank.)

→ This will be a dedicated test mode processing.

On the P-CON, when power is turned off once and, then,

turned on again, (Power OFF → ON) the unit will be re-

started.

● Special display when set to TUNER

When in TUNER mode, if any of the following displays appear,

there is an abnormality with the front end.

• “TNE2P_NG” : At production site, the E2PROM is still with

the default (unspecified) value, due to the fact that the front-

end being shipped without going through the adjustment

process.

•“TNCON_NG” : In this condition, the communication with

the front-end is not possible.

● Forced switching of K3I

In TUNER FM mode, each time [6] key is pressed, the func-

tions move in the following cycle :

AUTO → forced WIDE → forced MIDDLE → force NARROW

→ AUTO

The initial condition is AUTO and the displays below will ap-

pear.

• AUTO : FMA

• Forced MIDDLE : FMM

• Forced WIDE : FMW

• Forced NARROW : FMN

● CD receiver test mode specifications

•Jumps are made to the following tracks by pressing the

[

] key.

No. 9 → No. 15 → No. 10 → No. 11 → No. 12 → No. 13 →

No. 22 → No. 14 → No. 9 (Returns to the beginning)

It must be noted, however, that when paying MP3 / WMA /

AAC disk, which contain 8 files or less, the first track and

the following tracks are played in order.

• When [ ] key is pressed, it goes down by 1 track.

• When a CD is used as a source, by pressing [1] key for less

than 1 second, a jump to the Track No. 28 is made.

• When a CD is used as a source, by pressing [2] key for less

than 1 second, a jump to the Track No. 14 is made.

• When a CD is used as a source, by pressing [3] key for less

than 1 second, a display of CD mechanism model name

and its version is made. When the pressing of [3] key for

less than 1 second is made for the second time, the normal

display is resumed. (Time code display)

• When a CD is used as a source, by pressing [6] key for less

than 1 second, a jump to the Track No. 15 is made. At the

same time, the volume value is set to 25 (2V PRE) and 27

(5V PRE).

TEST MODE

2. When entering the test mode, the manufacture code of the

Flash ROM (4M) is read and when it is normal, FROMCHK

of the 100th terminal (Panel µ-com) repeats Hi → Low →

Hi · · ·. If the reading is abnormal, “Low” is output.

If the manufacture code is normal, by pressing [ ] key for

less than 1 second, the connection checks on all terminal

is started. If the connections are normal, the FROMCHK

terminal stops the Hi → Low → Hi · · · repeating and out-

puts “Hi”. If the reading is abnormal, “Low” is output.

3. With all lights turned on and by pressing [AM] key for at

least 1 second, the data on the Flash ROM (4M) is initial-

ized. While erasing the data, “Data_Erase....” is displayed.

Note : Do not touch any key white this is in progress.

When erasing is complete, “Erase_OK!!” is displayed.

If “Erase_NG!!!!!!” is displayed, it was not possible to erase

the data on the Flash ROM (4M).

In this case, pressing [AM] key for at least 1 second again.

If it is the same, then there is an abnormality with the Flash

ROM.

● Other

• At Power ON, “CODE_OFF”, “CODE_ON” displays will not

be made.

• When sourcing STANDBY, by pressing [AUTO] or [TI] key

for less than 1 second, GREEN/RED of the key illumination

is switched.

When doing this, the triangle illumination GREEN/RED is

switched along with the key illumination.

• When staring up in the test mode, LINE MUTE prohibition

time is set to 1 second instead of 10 seconds.

• While in the test mode, even when a DC offset error is de-

tected, the detection information will not be written to the

E2PROM.

• While in the test mode, even after an elapse of pre-set time,

the backup memory items will not be written to the E2PROM.

• Information Clear mode for Test Mode, backup/installer

memory, and CD mechanism error log.

In the DC offset error detection information clear mode,

DEMO mode operation will not be conducted.

Also, in the above mode, the menu of the STANDBY source

will not display DEMO ON/OFF switching items.

• While in the test mode, and at the same time, PM_DET of

the 60th terminal (System µ-com) is H, the following will

apply to the EJECT key, regardless of whether a disc is in

the unit or not.

Panel full OPEN/CLOSE is conducted with a push for less

than 1 second. (Protection time : 3 seconds)

As far as this item is concerned, eject will be achieved by

for at least 1 second push on the EJECT key.

● Clearing backup memory and installer memory

data (Clearing E2PROM data)

1. By pressing [ ] (NEXT) key and [ATT] key simultaneously,
