5. SYSTEM ERROR

Check 1

• Indication of abnormalities with the EEP-ROM

(HDMI PWB / IC89) Interface

This indicates a communication error wherein the ACK will

not return for 2 seconds or more while the system is in com-

munication with the EEP-ROM (INPUT PWB / IC89).

- Message on FL displayw.

Points to be checked

1. The IIC Clock Line (IC105/116 pin . IC89/6 pin) is normal

when the power is ON.

2. The IIC Data Line (IC105/117 pin . IC89 / 5 pin) is normal

when the power is ON

3. The IC89/8 pin is supplied with VCC +3.3V.

4. If none of the above is negative, the IC89 may be having

a defect.

Check 2

• +5V supply Error Detection (_5V DOWN)

When the power is turned on or while the unit is in normal

operation, an abnormality occurs with the +5V power

supply, and the +5V power into the CPU 137 pin cannot be

detected.

• Detection of DC on Power Amp Output

(_P AMP FAIL)

When the power is turned on or while the unit is in normal

operation, an abnormality occurs with the Power Amp, and

DC is detected on the CPU 121 pin.

• Detection of abnormal heat of Power Amp

(_P AMP FAIL)

The Power Amp is overheated while in normal

operation,with an abnormality detected on the CPU 121

pin.

• Detection of Overcurrent below 200msec on

Power Amp (_P CUR FAIL)

When the product is in normal operation, an abnormality

occurs with the POWER AMP, and an overcurrent of less

than 200msec is detected on the CPU 120 pin.

When errors like the above abnormalities are detected, the

software automatically puts the product into STANDBY

mode, with the STANDBY LED flickering approximately

every 500msec.

NOTE : The product can recover from the SYSTEM ER-

ROR when the user turns on and then off the

STANDBY. However, once any of the above errors

is redetected, the product goes into STANDBY

again.

Points to be checked

1. The CN81 (HDMI PWB) 7 & 8 pins are supplied with +5V

when the power is ON

2. The CN85 10pin (Power Amp Fail) is outputting the "H"

signal; (If the 10 pin continues to be in the "L" state for 2

seconds or more after the power is turned ON, the Power

Amp circuit is having a problem.)

CHECK E2P I F

19

3. Check that the speaker cable connected to the product is

not in contact and shorting out.

4. The Microprocessor 25 pin (Power Down) is outputting

the "H" signal when the power is turned ON. (If the 25pin

continues to be in the "L" state after the power is turned

on, the MAIN PWB circuit , the IC60 and its adjacent cir-

cuits are developing an abnormality.)

NOTE : HOW TO RECOVER FROM SYSTEM ERROR

(STANDBY LED flickering) The product can recov-

er by turning on STANDBY on the remote control-

ler after the above errors are rectified.

Check 3

• Detection of Overcurrent over 200 msec on POW-

ER AMP (_P CUR FAIL)

When the power is turned on or while the product is in nor-

mal operation, an abnormality occurs with the POWER

AMP, and an overcurrent of 200msec or more (500msec or

more when the power is on) is detected on the CPU 120

pin.

• Detection of an abnormality on +/-12V Supply or

Power Amp power supply (_P LINE FAIL)

When the power is turned on or while the product is in nor-

mal operation, an abnormality occurs with the +/-12V sup-

ply or POWER AMP power supply with an abnormality

detected on CPU 122 pin.

When errors like the above abnormalities are detected, the

software automatically puts the product into STANDBY

mode, with the STANDBY LED flickering approximately

every 125msec.

NOTE : This SYSTEM ERROR cannot be rectified by

users. In order to power on the product, please do

the following.

: Hold down "SURROUND MODE", "EXIT" &

"CLEAR" at the same time for 3 seconds or

more. However, if any problem remains with

the product, the SYSTEM ERROR will occur

again.

Points to be checked on the circuit

1. Check that the 120 pin (_P CUR FAIL) of the

microprocessor is outputting "H". (If the 120pin is in the

L-state for 500msec or more after the power is turned on,

the POWER AMP circuit is developing an abnormality.)

2. Make sure that the 122pin of the microprocessor

(POWER LINE FAIL) is "H". (If the 122 pin is in the

L-state for 2 seconds or more after the power is turned

on, the +/-12V power supply or the POWER AMP power

supply is developing an abnormality.)

8. DUAL BACKUP MEMORY

This product has a Dual Backup Memory function. The

conventional Backup functions to memorize, in the EEP-

ROM (IC89) in the circuit, a current setting of the moment the

main power is turned off so that it can be restored when it is

turned ON again. Meanwhile, the DUAL BACKUP MEMORY

is capable of memorizing any arbitrary setting that is

configured while the product is in operation so as to restore

it at any time.

When servicing units returned from end-users for repairs,

use this function to back up the current setting (e.g. Tuner

Preset). This will enable the units to be returned to the users

after repairs, with the setting unchanged.

NOTE : If end-users use this function, the data will be

overwritten.

• HOW TO OPERATE

-Backup-

1. Configure a setting you would like to save in the MEMO-

RY and hold down the [MEMORY] and [ENTER] buttons

on the Front Panel at the same time for 3 seconds or

more.

2. The FL Display indicates "MEMORY SAVING" while the

Backup is being performed.

3. The FL Display indicates "COMPLETE" when the Backup

is completed.

-Recovery-

1. Hold down the [MEMORY] and [MENU] buttons on the

Front Panel at the same time for 3 seconds or more. s

2. The FL Display indicates "MEMORY LOAD" while the

Recovery is being performed.

3. After the FL Display indicates "COMPLETE", the product

goes into Standby mode. When the power is restored, the

Recovery is completed. The FL Display indicates "NO

BACKUP" if the DUAL BACKUP MEMORY has not been

activated with no data to be recovered saved in the

Memory. This function does not back up the levels of

Main ZONE Volume, ZONE A Volume and ZONE A

Speaker Volume. When the Recovery is done, - is indi-

cated.

• SERVICE PRECAUTIONS

When the Flash Rom (IC89) on the INPUT PWB is replaced

or when the DSP CODE is rewritten for a version upgrade,

make sure, in order to maintain consistency with the Backup

Memory, to clear the DUAL BACKUP MEMORY in

thefollowing way :

-How to clear the Backup Memory--

1. Hold down the [MEMORY] and [CLEAR] buttons on the-

Front Panel at the same time for 3 seconds or more. s

2. The FL Display indicates "BACKUP CLEAR" while the

memory is being cleared.

3. After the FL Display indicates "COMPLETE", the opera-

tion is completed.
