Self-diagnosis Function
(When letters/numbers appear in the
display)
When the self-diagnosis function is
activated to prevent the system from
malfunctioning. In this case a five-character
service number (e.g., C 13 00) with a
combination of a letter and digits appears on
the screen and the front panel display. Refer
to the following table.
First three
characters of
the service

(xx is a number)
Cause and/or Corrective
Action
The disc is dirty.
, Clean the disc with a soft
cloth.
The disc is not inserted
correctly.
, 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 5-character
service number.

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. The label
is located on the bottom exterior.
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 man ufacturers’ instructions to use these
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a V OM
or battery-operated A C voltmeter . The “limit” indication is 0.75
V, so analog meters must have 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 Fig. A)

SER VICING NOTES
HCD-S550/S880
Ver 1.6
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.
JIG ON REPAIRING
When repairing this set, etc., connect the extension cable as the
figure shown below.
RELEASING THE DISC SLOT LOCK
The disc slot lock function for the antitheft of an demonstration
disc in the store is equipped.
CHECKING OF OPERATIONS WITH REMOTE COMMANDERS OF DIFFERENT MODELS
Some of the signal of remote commander vary between generation of player.
Between DAV-S400/S500/S800/C450/C700/C900 and DAV-S550/
S880/C770/C900, remote commander signal codes of “FUNCTION”, “BAND”, “ST/MONO” and “MEMORY” are different.
Take notice of the above when you check the operation with remote commanders of different models.
NOTE OF REPLACING THE DVD BOARD
When replacing the DVD board, since the adjustment value is not
set up correctly, “Drive Auto Adjustment” can’t be performed.
In this case, initialize Memory in the following procedures.
Procedure:
1. Set the test mode. (See page 20)
2. Press the [2] key of the remote commander , and set the “DRIVE
MANUAL OPERATION”. (See page 22)
3. Press the [6] key of the remote commander, and set the “2-6,
Memory Check”. (See page 24)
4. Press the [CLEAR] key of the remote commander, and initialize Memory.
Releasing Procedure:
1. Press two buttons of A and x simultaneously for three seconds.
2. The message “UNLOCKED” is displayed and the slot is unlocked.
Note: When “LOCKED” is displayed, the slot lock is not released by
turning power on/off with the [POWER] button.
