Notes on chip component replacement
•Never reuse a disconnected chip component.
•Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
•Keep the temperature of the soldering iron around 270 ˚C dur-
ing 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 ra-
diation exposure.

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
number

(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

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 electro-
static 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 emis-
sion, observe from more than 300 mm 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.
Releasing Procedure:
1. Press two buttons of Aand xsimultaneously for three sec-
onds.
2. The message “UNLOCKED” is displayed and the slot is un-
locked.
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 DAV-S550/
S880/S888/C770/C900, remote commander signal codes of
“FUNCTION”, “BAND”, “ST/MONO” and “MEMORY” are dif-
ferent.
Take notice of the above when you check the operation with remote
commanders of different models.

TEST MODE
[GENERAL DESCRIPTION]
The Test Mode allows you to make diagnosis and adjustment easily
using the remote commander and monitor TV. The instructions,
diagnostic results, etc. are given on the on-screen display (OSD).
After parts related to the servo circuit (RF amplifier (IC001), DSP
(IC401), motor driver (IC501), EEPROM (IC302) so on) are
replaced, re-adjusting the servo circuit is necessary. Select “ALL”
at “1. DRIVE AUTO ADJUSTMENT” (Refer to page 20 inTEST
MODE) and adjust DVD-SL (single layer), CD and DVD-DL
(duallayer).
[TEST DISC LIST]
Use the following test disc on test mode.
TDV-520CSO (DVD-SL): PART No. J-2501-236-A
LUV-P01 (CD): PART No. 4-999-032-01
TDV-540C (DVD-DL): PART No. J-2501-235-A
Note:Do not use exiting test disc for DVD.
[STARTING TEST MODE]
1. Press the [POWER] button to turn the power on, and set the
function to DVD.
2. While pressing the xand [DISPLAY] button, turn the
[VOLUME] knob clockwise to enter the test mode.
3. It displays “TEST MODE” on the fluorescent indicator tube,
and displays the Test Mode Menu on the monitor screen as
follows. (At the bottom of the menu screen, the model name
and revision number are displayed)

Normally, [10/0] is selected to adjust DVD (single layer), CD and
DVD (dual layer) in this order. But, individual items can be adjusted
for the case where adjustment is suspended due to an error. In this
mode, the adjustment can be made easily through the operation
following the message displayed on the screen.
The disc used for adjustment must be the one specified for
adjustment.

Press the [10/0] key on the remote commander, and the servo set
data in EEPROM will be initialized. Then, 1. DVD-SL disc, 2. CD
disc and 3. DVD-DL disc are adjusted in this order.
Each time one disc was adjusted, it is ejected. Replace it with the
specified disc following the message.You can finish the adjustment
by pressing the [RETURN] button on the remote commander.
Note: During adjustment of each disc, the measurement for disc type judg-
