SELF-DIAGNOSIS
Self-diagnosis Function
(When letters/numbers appear in the
display)
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.
C:13:00
First three
characters of
the service
number

C 31
E XX
(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 self-
diagnosis function.
, Contact your nearest Sony
dealer or local authorized
Sony service facility and
give the 5-character
service number.

SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks 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
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 microampers).
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 manufacturers' 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
VOM or battery-operated AC 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 2V AC range are suitable. (See
Fig. A)
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 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.
Laser component in this product is capable of emitting radiation
exceeding the limit for Class 1.
This appliance is classified as
a CLASS 1 LASER product.
The CLASS 1 LASER
PRODUCT MARKING is
located on the rear exterior.
This caution
label is located
inside the unit.

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.
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
Carry out the "S curve check" in "CD section adjustment" and check
that the S curve waveform is output several times.

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.Starting test mode. (See page 18)
2.Press the [2] key of the remote commander, and set the "DRIVE
MANUAL OPERATION". (See page 24)
3.Press the [6] key of the remote commander, and set the "6. Memory
Check". (See page 26)
4.Press the [CLEAR] key of the remote commander, and initialize
Memory.
