(5) About keeping the disc
As for the DVD test disc, plane accuracy is demanded.Please note the keeping place on the disc.
1. Please do not put the disc directly on the work desk etc. after uses .
2.To keep the planarity of the disc, politely handle ,and please put in a special case and keep
the disc vertically after uses .
Please keep keeping the disc in a cool place where direct sunshine and the air-conditioning
wind do not drive.
3.When the disc curves,an accurate adjustment cannot be done.
Please exchange for a new test disc and adjust optics.
4Other discs might not be able to be reproduced when adjusting on a curved disc.
Point of adjustment
* Please execute the static electricity protection measures before starting the
adjustment.
* When the following parts are exchanged,optical adjustment "Adjust the flap of the disc motor"
is necessary.
1.The disc motor was exchanged.
2.The laser pick up was exchanged.
3.The traverse motor unit was exchanged.
Note
Additionally, please adjust the flap of the disc motor when the picture quality deterioration is
seen .The basic adjustment though, is unnecessary for part exchange in the traverse.
An optical adjustment in the laser pick up cannot be done.
Please adjust the flap of the disc motor after exchanging the laser pick up.
* When the traverse unit is exchanged, the adjustment is basically unnecessary.

Check points for each error
6
(1) Spindle start error
*Defective spindle motor
Are there 10ohms resistance between each pin of CN101 "29~31"?
(The power supply is turned off and measured.)
*Hall element: Is sine wave output between CN101 "23" and "24", between "25" and "26",
and between "27" and "28" during rotation?
In either case, replace the mechanical unit.
*Defective spindle driver (IC251)
Is a driving wave output from CN101 "29~31" ?
During
rotation
Is IC251 "9" at "H" level (START)?
Servo IC --- Is control signal sent to the motor driver ?
IC201 "95" : Duty is 50% during stop, but varies during rotation (greatly varies at start).
--- If not sent, pattern or servo IC (IC201) is defective.
R259 : approx 2.5V during stop, but varies during rotation (greatly varies at start).
--- of not sent, pattern or servo IC (IC201) is defective.
Is FG input to servo IC ?
Observe FG wave from IC201 "89". --- If not output, pattern, IC251 or IC201 is defective.
(2) Disc Detection, Distinction error (no disc, no REFNV)
* Laser is defective.
* Front End Processor is defective (IC101).
* APC circuit is defective. --- Q101.
* Pattern is defective. --- Lines for CN101 "15" and "17".
Lines for between IC201 "2" and IC101 "2"(LDONA),
between IC201 "3" and IC101 "1" (LDONB).
* Servo IC is defective (IC201).
* Is signal sent to IC201(servo)"71" AS2 ?
* IC101 --- For signal from IC101 to IC301, is signal output from IC101 "88" (RFAS1) and
IC101 "69" REENV ?
Page 7
(3) Traverse movement NG
7
* For automatic adjustment, traverse movement occurs only when the position is changed to retry
judging the disc type after the 1st judgment resulted in an error. Therefore, traverse movement
rarely occurs because, in most cases, disc judgment at the current position (1st time judgment)
is executed successfully. (Of course, NG rarely occurs in this step.)
Note: 1st time judgment of disc type resulted in NG. --- The re-judgment of disc type may not be
successful. Therefore, after removing the cause of traverse movement, re-execute automatic
adjustment and confirm that no problem exists.
* Check point
a)During stop
Whether 50% duty pulse is output to R273
Whether between R274 and C271 is at approx. 2.5VDC
Offset voltage between CN101 "34" and "35" (scores mV if exists)
b)When tray is opened or closed
Check by oscilloscope whether a rectangular wave signal is output from CN101 "34" or "35".
50msec
2.5V
Approx.
500mV
GND
If checking a) or b) resulted in NG, IC201 maybe defective.
(4) Focus ON NG
* Is FE output ? --- Pattern, IC101
* Is FCDRV signal sent ? (R286) --- Pattern, IC301
* Is driving voltage sent ?
CN101 "20", "21" --- If NG, pattern, driver, mechanical unit (with the power turned off, measure the
resistance between CN101 "20" and "21").
* Does CN101 "7"(SRF1) become "H" and is the focus drawing in done?
--- Mechanical unit (laser power too low), IC101(defective gain)
--- Moreover, It is thought that abnormality is found in the disk.
* Mechanical unit is defective.
(5) Tracking ON NG
* When the tracking loop cannot be drawn in, IC201 "39" (/TRON) does not become "L".
* Mechanical unit is defective.
Because the undermentioned adjustment value is abnormal, it is not possible to draw in normally.
* Periphery of driver (IC271)
Constant or IC it self is defective.
(When passing without becoming abnormal while adjusting the following.)
* Servo IC (IC201)
When improperly adjusted due to defective IC.
* When the spindle cannot be shifted to CLV Servo, does not become "H" between IC301 "69"
and IC201"37".
* IC201 Is signal output from CN103 "1" (RFOP)?
* IC201 Is signal output from CN103 "11" (DSLIP)?
* IC201 Is signal output from CN103 "6" to "9" (binary-coded clock and data)?
* IC201 Is "39" (/TRON) at "L" level ?
* IC301 "74" to "76" --- Is signal output to IC201 "24", "25", "28" (In case of only CD).
(Serial communication of rotation information)
* Spindle motor driver is defective.
Even when one of the three phases is defective, item (1) may be passed.
--- Check the second item in (1) above.
* C260 to C263 Defective soldering
If noise eliminating capacitors are not properly soldered, noise may ride on the waveform.
* Besides, the undermentioned cause is thought though specific of the cause is difficult because various
factors are thought.
Mechanism is defective.(jitter)
IC101, IC201.
(7) Address read NG
* Besides, the undermentioned cause is thought though specific of the cause is difficult because various
factors are thought.
Mechanism is defective. (jitter)
IC201, IC301, IC401.
The disc is dirty or the wound has adhered.
(8) Between layers jump NG (double-layer disc only)
* When the focus flight is generated when jumps between layers.
Because all adjustments for L1 layer must be successful, this error may rarely be due to a
circuit defect.
* Crosstalk might occur from tracking to focus system. (See (11) ) --- Replace the mechanical unit.
* Driver surroundings.
* Defect of constant and IC.
* For double-layer discs, after checking CLV on layer L1, jumps to layer L0 after mode changes to FG.
Then tracking is turned off, and adjustments are executed from the focus position coarse adjustment
in order.
* When the jump between layers is done on the single-layer disk, the disk distinction error is thought.
--- The laser power is low (RF level is confirmed by CN102 "1" (RFOP)).
--- AS1, AS2, REFNV Is the signal sent to between IC101 and IC201 ?
Page 9
(9) Neither picture nor sound is output
9
* Cannot search
a) Can the feed system be driven?
Check the waveform of TRSDRV signal (R273). --- Waveform between R274 and C271.
Search results in a change of duty
(three values with 2.5V at the center)
(The figure is exaggerated.)
Check the waveform of CN101 "1" and "2". --- After the driver (IC271)
Approx.
2.5V
For short-distance search, the waveform
becomes roundish, not trapezoidal, and
voltage is low.
b) Is kick available?
Check the TRDRV signal waveform from R289.
Check the waveform of CN101 "22" and "23" --- After the driver (IC271)
Although differs in amplitude and DC offset, the waveform is similar to that of R289

Does JITOUT
change periodically?
(2V or more in peak
value, except
during kick)
YES
Feed system is defective (drive gain is defective: too large).
Check the waveform according to a) in (9).
Play back a simple disc with no angle change.
OK when the following waveform appears at intervals
of several seconds.
5~10Sec.
1~1.2V
Some system other
NO
than servo may be
defective.
If this voltage is too
high (2V or more, for
example), feed motor
may be defective, or
the mechanical unit
has seized.
(11) Others (unusual events experienced to date)
* Problem occurs with double-layer discs although no problem occurs with single-layer DVD.
(Error occurs, or search becomes unstable and takes longer.)
Crosstalk might occur from tracking to focus system.
--- When FE was observed during search (skip, etc.), it was found that a wave resembling TE
with an amplitude of 200mVp-p was riding on FE.
--- Mechanical unit was replaced.
* Error frequently occurred in the outer part of discs although no error occurred in the inner part.
--- Mechanical unit was replaced because tilt seemed to be defective.

Precautions for Service
11
Handling of Traverse Unit and Laser Pickup
1. Do not touch any peripheral element of the pickup or the actuator.
2. The traverse unit and the pickup are precision devices and therefore must not be subjected to
strong shoc k.
3. Do not use a tester to examine the laser diode. (The diode can easily be destroyed by the
inter nal power supply of the tester.)
4. To replace the traverse unit, pull out the metal short pin for protection from charging.
5. When replacing the pickup, after mounting a new pickup, remove the solder on the short land
which is pro vided at the center of the flexible wire to open the circuit.
6. Half-fixed resistors for laser power adjustment are adjusted in pairs at shipment to match the
char acteristics of the optical block.
Do not change the setting of these half-fix ed resistors for laser power adjustment.
Destruction of Traverse Unit and Laser Pickup by Static Electricity
Laser diodes are easily destroyed by static electricity charged on clothing
or the human body . Before repairing peripheral elements of the traverse
unit or pic kup, be sure to take the following electrostatic protection:
1. Wear an antistatic wrist wrap.
2. With a conductive sheet or a steel plate on the workbench on which
the traverse unit or the pick up is to be repaired, ground the sheet
or the plate.
3. After removing the flexible wire from the connector (CN101),
short-circuit the flexible wire by the metal clip.
4. Short-circuit the laser diode by soldering the land which is provided
at the center of the flexible wire for the pickup.
After completing the repair , remove the solder
to open the circuit.
