Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be damaged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C during repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation exposure.
This appliance is classified as a CLASS 1
LASER product.

SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED

SECTION 1
SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated
by the charged electrostatic load, etc. on clothing and the human
body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
on the disc reflective surface by the objective lens in the optical
pick-up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
CLEANING OF OPTICAL PICK-UP LENS
In cleaning the lens of optical pick-up, use the air blower.
Never use a cotton swab for cleaning the lens of optical pick-up,
which otherwise causes a trouble.
HOW TO OPEN THE TRAY WHEN POWER SWITCH TURNS OFF

TEST MODE
In this set, various checks are automatically performed by executing
the commands in the test mode.
Note: This set makes adjustment every optical pick-up and stores its result
in the EEPROM (IC903) on the MAIN board. Accordingly, if a
combination of optical pick-up and EEPROM is changed, be sure
to perform 4-3. SET CHECK. Also, perform 4-1. IC INTERFACE
CHECK, 4-2. DISPLAY CHECK, and 4-6. WAVEFORMS CHECK.

Setting Method of Test Mode
Turn the [POWER] button on while pressing the [l AMS L]
dial and the [MENU] button. Release the [MENU] button and the
[l AMS L] dial in this order when “DIAG MODE” is displayed
on the fluorescent indicator tube.
Releasing Method of Test Mode
To release the test mode, turn the [POWER] switch off.
Selection/Entry of Test Mode
To select and enter the “DIAG MODE”, operate as follows.
1. Rotate the [l AMS L] dial to select the menu, and press
the [l AMS L] dial to enter.
2. The test is switched on or off alternately each time the
[l AMS L] dial is pressed.
3. To return to the previous step, rotate the [l AMS L] dial
to select the desired item, and press the [l AMS L] dial
to enter.

4-1. IC INTERFACE CHECK
The communication between microcomputer and main ICs is
checked.
Checking Method:
1. After setting the test mode, rotate the [l AMS L ] dial to
select “A0. IC SELF CHECK” and press the [l AMS L]
dial to enter.
2. A checking will start automatically. (Checking time is about 3
seconds)
3. At successful completion of check, “IC CHECK OK” is displayed. In this case, no error exists in the IC interface.
Note: The check mentioned above tests the communication from microcomputer to main ICs. Even if the check successfully finished, the
IC to be checked is not always normal. Consider it for reference
only.
4. In case of an IC communication error, the following display
will be given during the checking. Possible causes of error are
as listed below.
Error display
Causes (typical example)

CD DSP ERROR
14
1. IC509 (CD DSP) is faulty
2. 768fs (33.8688 MHz) is not present to
IC509 pin ua (XTAL)
Same as cause 3 of DVD DEC. ERROR
3. IC509 pin 2 (XRST) does not go “H”
• IC901 pin ts (XDIS IO) does not go “H”
• IC904 (PLD) is faulty
Causes Common to Each IC:
1. Faulty communication line between microcomputer and each
IC.
Disconnected patterns, floating series resistors, bridge, etc.
2. Faulty IC supply voltage.
Particularly, check D+3.3V voltage.
3. Faulty microcomputer communication port to each IC
Note: In case of more than two errors, the error display is switched over
one after another, thus making the reading difficult.
In such a case, press again the [ l AMS L ] dial to make a
recheck for error reading.
4-2. DISPLAY CHECK
Checking Method:
1. After setting the test mode, rotate the [l AMS L ] dial to
select “8A. FL CHECK” and press the [l AMS L] dial to
enter.
2. Respective segments of fluorescent indicator tube will
automatically light up in order, and therefore check that there
is no chipped character.
3. The “INPUT REMOCON” will be displayed after the segment
check finished successfully, and then press a proper key on
the remote commander.
4. After “JOG CHECK” is displayed, the numbers of calendar
will be displayed from 1 to 15 each time the [l AMS L]
dial is rotated clockwise.
5. After display up to 15, the numbers of calendar will
disappear in order each time the [ l AMS L ] dial is
rotated counterclockwise.
6. “TTX-1514?” will be displayed when all are cleared, and then
press the [ l AMS L ] dial.
7. Upon display of “KEY CHECK”, if a key on the display is
pressed, the corresponding segment of fluorescent indicator
tube will light up.
8. “FL TEST END” will be displayed if all keys are pressed.
Note: The keys include the [ l AMS L ] dial. If the segment that
corresponds to the pressed key does not light up, that key is faulty.
9. The test mode selection display will be back, if the [lAMS L]
dial is pressed.
SCD-XB790
4-3. SET CHECK (AUTOMATIC VARIOUS MEASUREMENTS)
The operational stability of the set is checked. The check and OK/NG judgment are performed automatically.
Note: In the set check using the CD, besides a checking, the MIRR time used for the disc check is measured every optical pick-up, and from the measured
result, the threshold value is calculated and it is stored in the EEPROM (IC903) on the MAIN board. Accordingly, if a combination of optical pickup and EEPROM is changed (for example, the optical pick-up or MAIN board is replaced), be sure to perform the set check using the following CD.
As the data stored in the EEPROM are overwritten every set check, retry if failed. For the set check using the SACD, only checking is made.
Set Check
92. SET CHECK
AUTO CHECK SP?
The set check is executed to judge OK or NG.
(For the CD, the threshold value is stored in the EEPROM)
AUTO CHECK?
The set check of measurement only is executed.
DISP RESULT S?
The measured result is displayed via RS-232C.
DISP RESULT F?
The measured result is displayed on the fluorescent indicator tube.
CHECH END?
The set check is finished.
CD and SACD (SL) Disc Operation Check
Checking method:
1. After setting the test mode, rotate the [ l AMS L ] dial to select “SET CHECK” and press the [ l AMS L ] dial to enter.
2. Upon display of “AUTO CHECK SP?”, further press the [ l AMS L ] dial.
3. The tray will open automatically, and then set the test disc*1 of CD or SACD.
4. With the “DISC IN&JOG ON” displayed, press the [ l AMS L ] dial, and the check will be executed automatically.
5. “SPEC OK!” will be displayed if the measured result is within the specification. Faulty item name and the measured result will be
displayed if any measured item is NG.
6. After that, “AUTO CHECK SP?” will be again displayed, and then rotate the [l AMS L] dial to select “CHECK END?”. Further,
press the [l AMS L] dial, and the test mode selection display will be back, and then press the [OPEN/CLOSE A] button and take
the test disc out.
*1 Use PATD-012 or YEDS-18 for CD, and SATD-S5 or SATD-S4 for SACD (SL). Using another disc will result in a checking failure.
