and must be replaced with parts having specifications equal
to those originally installed.

2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.

● Meter impedance should be equivalent to 1500 ohm shunted

by 0.15µF.

● Leakage current must not exceed 0.5mA.

Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes
or expose eyes to solder/flux vapor!

TEL

If you come in contact with solder or components located inside the enclosure of this product, wash your hands
before handling food.

WARNING: Laser Safety

This product contains a laser beam component. This component may emit invisible, as well as visible radiation,
which may cause eye damage. To protect your eyes and skin from laser radiation, the following precautions must
be used during servicing of the unit.

1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm away from
the laser pick-up unit at all times. Do not stare at the laser beam at any time.

2) Do not attempt to readjust, disassemble or repair the laser pick-up, unless noted elsewhere in this manual.

3) CAUTION : Use of controls, adjustments or performance of procedures other than those specified herein may result in
hazardous radiation exposure.

Laser Emitting conditions:

1) When the Top Cover is removed, and the STANDBY/ON SW is turned to the "ON" position, the laser component will
emit a beam for several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate through
the lens of the laser pick-up unit. Do not attempt any servicing during this period!
If no disc is detected, the laser will stop emitting the beam. When a disc is loaded, you will not be exposed to any laser
emissions.

TEL [phone] QQ 376315150 892498299

2. Handling of the optical pickup

1. To prevent damage to the optical pickup replacement parts during transportation and before installation, both ends

of the laser diode are short-circuited. After installing the new part, remove the short circuit according to the correct
procedure in this service manual.

2. Do not use a tester to check the laser diode in the optical pickup. The power supply in the tester will damage the

laser diode.

1.1 Purpose of Dealer Script

1.2 Contents of Dealer Script

The dealer script executes all diagnostic nuclei that do not
need any user interaction and are meaningful on a standalone
DVD player.
The nuclei called in the dealer script are the following (the
number after each nucleus name corresponds with the number
being on the local display when the nucleus is executed during
the dealer script):

The dealer script can give a diagnosis on a standalone DVD
player, no other equipment is needed to perform a number of
hardware tests to check if the DVD player is faulty. The
diagnosis is simply an "error" or "pass" message. No
indication is given of faulty hardware modules. Only tests
within the scope of the diagnostic software will be executed
hence only faults within this scope can be detected.

2 Player Script

2.1 Purpose of Player Script

Q

Q

The Player script will give the opportunity to perform a test that
will determine which of the DVD player's modules are faulty, to
read the error log and error bits and to perform an endurance
loop test. To successfully perform the tests, the DVD player
must be connected to a TV set to check the output of a number
of nuclei. For DVDv2b a multi-channel amplifier, a set of 6
speakers and an external video source are necessary to test.
To be able to check results of certain nuclei, the player script
expects some interaction of the user (i.e. to approve a test
picture or a test sound). Some nuclei (e.g. nuclei that test
functionality of the Basic Engine module) require that the DVD
player itself is opened, to enable the user to observe moving

DVD-C940

/DV-C6680

TEL [phone] QQ 376315150 892498299

parts and approve their movement visually. Only tests within
the scope of the diagnostic software will be executed hence
only faults within this scope can be detected.

2.2 Contents of Player Script

The player script contains all nuclei that are useful on a DVD
player that is connected to a TV set and help to determine
which module of the DVD player is faulty, as well as to read out
the contents of the error logs.

2.3 Structure of Player Script

The player script consists of a set of nuclei testing the three
hardware modules in the DVD player: the Display PWB, the
Digital PWB, and the Basic Engine.
Nuclei run by the player test need some user interaction. In the
next paragraph this interaction is described. The player test is
done in two phases:

TEL

1. Interactive tests: this part of the player test depends
strongly on user interaction and input to determine nucleus
results and to progress through the full test. Reading the
error log and error bits information can be useful to
determine any errors that occurred recently during normal
operation of the DVD player.

The loop test: this part of the player test will loop through

2.

the list of nuclei indefinitely, untill the player is reset. The
list of nuclei is as follows:

PapChksFlash
PapI2cNvram
CompSdramWrR

By pressing OPEN/CLOSE the user confirms the test, pressing
STOP will indicate the picture was invisible or incorrect.
Pressing PLAY/PAUSE will proceed to the next test. If the user
presses PLAY/PAUSE without pressing OPEN/CLOSE or STOP
first, the result of this test will be TRUE (picture ok).

The picture test is performed by putting a predefined picture
(color bar PAL) on the display (nucleus VideoColDencOn),
and asking the user for confirmation.
The display will show the following message:

Note: The color bar must be simultaneously available on the
CVBS, YC, and RGB (or YUV) outputs available. On the SCART
only the CVBS and RGB signals will be available.

The first sound test is performed by starting a pink noise sound
that needs confirmation from the user (nucleus
AudioPinkNoiseOn).
The display will show the following message:

The internally generated color bar is still available on the CVBS
and Y/C outputs. And the pinknoise-signal is still available on
the cinch audio outputs. By pressing the OPEN/CLOSE button,
the internally generated color bar becomes visible again.

The second sound test is performed by producing a sine sound
(nucleus AudioSineOn). The signal can be stopped by pressing

display during the errorbits readout looks as follows:

The loop test will perform the same nuclei as the dealer test,
but it will loop through the list of nuclei indefinitely. The
display of the DVD player will display not only the three digits
indicating correct/faulty modules and the last found error code
(as mentioned, faults are detected as far as they can be
within the scope of the diagnostic software), but also a loop
counter indicating how many times the loop has been gone
through. If an error was detected, the display will remain as in
figure 34 until the user presses the PLAY/PAUSE key and
then it will continue to the next loop.
Example:

The 2-digit number on the right of figure 34 indicates the
number of times the loop test has been performed.

a fault. The rightmost two digits (03) refer to the faultcode
within that nucleus.

6.1 Errorlog

Explanation:

The application errors will be logged in the NVRAM. The
maximum number of error bytes that will be visible is 16. The
first word (4 digits) of the byte is the component identification,
the last word is the error code.
The diagnostics software will present a combination of this
component identification plus an error code on the local display
(and on the attached terminal). The last reported error is shown
as < 00000000, the oldest visible error as 00000000 > and the
errors in between as < 00000000 >.
The devices that may report errors are the serial controller
(UART), the basic engine (BE), the slave processor (SLPH),
the SACD Stream Manager (SSM) and the SACD Media
Access (SMA). The identification of these components is as
follows:

Component name Component identification

Serial controller (UART) 000A
Engine (BE) 0016
Slave Processor (SLPH) 001A
SACD Stream Manager

(SSM)
SACD Media Access (SMA) 002E
Diagnostic software (DS) Dxxx

TEL

The tables in the next chapters list the error code and
corresponding problem. The Explantion column has a more
detailed description and the most likely reason for the error.

Some Examples:

002E0000 (SMA reported a timeout error)
0016010A (Engine could not fully close or open the tray)
D0010001 (Flash checksum failed).
