SELF DIAGNOSIS FUNCTION

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.

C:13:00

First three
characters of
the service
number

C 13

C 31

E XX

(xx is a number)

Note: Refer to the “5. TEST MODE” (page 22) for another self-diagnosis

function.

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.
Example: E 61 10

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.

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 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 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)

This appliance is classified as a
CLASS 1 LASER product. The label
is located on the bottom exterior.

SERVICING NOTES

HCD-C770/C990

Ver 1.3

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 objecti ve 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.

Releasing Procedure:

1. Press two buttons of [DISC 1] and x simultaneously for five
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.

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 D AV -S550/
S880/C770/C900, remote commander signal codes of
“FUNCTION”, “BAND”, “ST/MONO” and “MEMORY” are
different.
Take notice of the above w hen you check the operation with remote
commanders of different models.

On this screen, the servo on/off control necessary for replay is
executed. Normally, turn on each servo from 1 sequentially and
when CLVA is turned on, the usual trace mode becomes active. In
the trace mode, DVD sector address or CD time code is displayed.
This is not displayed where the spindle is not locked.
The spindle could run overriding the control if the spindle system is
faulty or RF is not present. In such a case, do not operate CLVA.
