SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs, screws,
and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microamperes.).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT -540A. Follow the manuf acturers’ instructions to use these
instruments.
2. A battery-operated A C milliammeter . The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC v oltmeter. The “limit” indication
is 0.75 V, so analog meters must hav e an accurate low-voltage
scale. The Simpson 250 and Sanwa SH-63Trd are examples
of a passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2 V A C range are suitable. (See

CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.
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.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
HCD-DX315
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 °C higher
than ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

SERVICING NOTE
HCD-DX315
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 pickup block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH
1. Open the cover and turn POWER on with no disc inserted.
2. Confirm that the following operation is performed while
observing the objecting lens.
1) Confirm that laser beam is spread.
2) Up and down motion of the objective lens. (3 times)
DISC TRA Y LOCK
The disc tray lock function for the antitheft of an demonstration
disc in the store is equipped.
Setting Procedure :
1. Press the ?/1 button to turn the set on.
2. Press the [FUNCTION] button to set DVD function.
3. Insert a disc.
4. Press the x button and the A button simultaneously for f i ve
seconds.
5. The message “LOCKED” is displayed and the tray is locked.
Releasing Procedure :
1. Press the x button and the A button simultaneously for f i ve
seconds again.
2. The message “UNLOCKED” is displayed and the tray is
unlocked.
Note: When “LOCKED” is displayed, the tray lock is not released by
turning power on/off with the ?/1 button.
Self-diagnosis Function
(When letters/numbers appear in the
display)
When the self-diagnosis function is activated to
prevent the system from malfunctioning, a 5character service number (e.g., C 13 50) with a
combination of a letter and 4 digits appears on
the screen and the front panel display. In this
case, check the following table.
C:13:50
First 3
characters of
the service
number
C 13 The disc is dirty.
C 31 The disc is not inserted correctly.
E XX
(xx is a number)
When displaying the version
number on the screen
When you turn on the system, the version
number [VER.X.XX] (X is a number) may
appear on the screen. Although this is not a
malfunction and for Sony service use only,
normal system operation will not be possible.
Turn off the system, and then turn on the system
again to operate.
Cause and/or corrective action
,Clean the disc with a soft cloth
,Restart the system, then re-insert
the disc correctly.
To prevent a malfunction, the
system has performed the selfdiagnosis function.
,Contact your nearest Sony
dealer or local authorized Sony
service facility and give the 5character service number.
Example: E 61 10
Note on MAIN board replacement
New part of EEP ROM (IC1103) on the MAIN board cannot be used.
Therefore, if the mounted MAIN board (A-1179-147-A) is replaced,
exchange new EEP ROM (IC1103) with that used before the replacement.

PRECAUTION BEFORE UNSOLDERING THE STATIC ELECTRICITY
PREVENTION SOLDER BRIDGE
When installing a new OP unit, be sure to connect the flexible
printed circuit board first of all before removing the static electricity
prevention solder bridge by unsoldering. Remove the static electricity
prevention solder bridge by unsoldering after the flexible printed
