SECTION 3
TEST MODE
Self-Diagnosis andTest Mode
This unit is provided with a “self-diagnosis and self-recovery func-
tion” which detects DSP errors and automatically recovers the unit,
and a test mode for performing operation checks during repairs.
1. Main Functions
• DSP self-diagnosis and self-recovery function
• Self-diagnosis for servicing and error message display
• Display of history of past DSP errors
• Various operation check mode
• SRAM, EEPROM check function
• Initialization (Differs according to country)
2. Entering the Test Mode
1. While pressing the AC-3 RF button and DIGITAL 2 button
simultaneously in the power OFF state, press the POWER but-
ton.
2. When theVOLUME LED starts blinking, release these buttons.
The self-diagnosis for servicing will be executed,and the opera-
tion check mode will be set.
(NOTE: Performing initialization will erase the error history.
Do not therefore press the wrong buttons. For details, refer to
“5. Initialization” on page 15.)
3. Self-diagnosis Mode for Servicing/Display of
History of DSP Errors
3-1. Self-diagnosis Mode for Servicing
Before entering the test mode, first the following self-diagnosis pro-
gram for servicing will be run.
1. Checks if unintended buttons are being pressed
2. Checks EEPROM (External memory device) operation
3. Read/write test of DSP external memory (1M SRAM)
4. Checks and displays history of various DSP abnormal operations
• When an error is detected:
The error message is displayed for about 8 seconds on the fluo-
rescent display tube,itis switchedto“MPEG/DOLBY DIGITAL”,
and the operation check mode is set. (See Table 1.)
When several errors occur at the same time, only the first error
detected will be displayed.
• When no error is detected:
“Ver. main X. X mpeg X. X” will be displayed, and the operation
check mode will be set. (X. X means its version No.)
Table-1:

rescent Display Tube Possible Reasons

3-2. Display of History of DSP Operations
• When “DSP error detected!” is displayed on the fluorescent dis-
playtube,thehistoryofDSPerrorswillbe displayed eight seconds
later. (See Fig. 1.)
• This history will be displayed if a DSP error has occurred in the
past. It helps the detection of malfunction parts by enabling past
problems of the unit to be checked.
• This history shows the “Cause of error” and “How many times
occurred” for the two DSPs. (See Fig. 1.)

4. Operation Check Mode
• During the operation check mode, functions can be set by press-
ing the corresponding button. (See Table-3.)
• Each time a button is pressed, the corresponding function will be
displayed for about 8 seconds.
• Buttons other than those displayed in Table-3 operate usually.
NOTE: Do not press the SET UP button during the operation
check mode. As this button is provided with a special
functionfordebugging,pressingitmay impede the normal
output of signals in the sub-woofer mode.

How to read the display
• The left side shows the errors of the first DSP (DSP56009:MAIN
board IC424) and the right side shows the errors of the second
DSP (SSP424023:MAIN board IC423).
• The “How many times occurred” indicates the number of times
that the error has occurred. If an error has occurred more than
256 times, it will be displayed as 256.
• The 1234part shows 0 or 1 according to the cause of the
error. If an error has occurred, 1 will be displayed. If no error has
occurred, 0 will be displayed. (See Table-2.)
Table-2:
Cause of error Possible cause
Mostlydueto faultyconnection (soldering)be-
tween DSP and microprocessor
Faulty DSP clock (X401 and onwards), faulty
DSP part, etc.
Overrunning of DSP due to heat,microproces-
sor bugging, or IC301 (MAIN board PLL) is
faulty
Faulty DSP part, or faulty microprocessor part,
etc.
1Failed in initial
booting
2DSP does not

4No reply from DSP
NOTE: This history is memorized in the EEPROM until the unit
is initialized. (Refer to “5. Initialization” on page 15.)

– 15 –
5. Initialization (Differs according to destination)
After executing the test mode, be sure to perform initialization.
• For J/SP/AEP Version (Use this procedure)
While pressing the AC-3 RF button and DIGITAL3 buttons
simultaneously, press the POWER button. When theVOLUME
LED starts blinking, release the buttons. “initialized (J/SP/AEP)”
will be displayed on the fluorescent display tube, and all internal
settings will be returned to the initial values.
• For U/CA version (Do not use this procedure)
While pressing the AC-3 RF button and DIGITAL4 buttons
simultaneously, press the POWER button. When theVOLUME
LED starts blinking, release the buttons. “initialized (U/CA)” will
be displayed on the fluorescent display tube, and all internal set-
tings will be returned to the initial values.
NOTE: As all histories of abnormal DSP operations will be erased,
note down the contents of the history beforehand.
6. Check of Pressing of Unintended Button
• This check is always performed when the power is turned ON.
Therefore when an error occurs, it can be known without setting
the test mode because theVOLUME LED blinks and the fluores-
cent display tube stops displaying.
• When an unintended button is pressed during the test mode or
initialization, theVOLUME LED also blinks, and the fluorescent
display tube stops displaying, preventing no mode to be set.
7. Other Functions
In the personal use of the unit at home, if no sounds are produced
due to DSP problems, the DSP will be rebooted automatically to
attempt recovery. If no sounds are still produced after five retries,
“Turn POWERSW off!” will bedisplayed on the fluorescent display
tube.
If this problem occurs, it indicates that the DSP is faulty or the
user’s setting environment may be unsuitable. Refer to “3. Self-
Diagnosis Mode for Servicing/Display of History of DSP Errors”
on page 13 to identify the problems.
