• The RFI and RFO signals are easy to oscillate because

of a wide band. When observing them, insert a resis-

rectly performed and recovery is disabled, the recov-
ery is enabled by resetting a product or turning ACC

6.4 CHECKING THE GRATING AFTER CHANGING THE PICKUP UNIT

• Note :
The grating angle of the PU unit cannot be adjusted after the PU unit is changed. The PU unit in the CD mecha-
nism module is adjusted on the production line to match the CD mechanism module and is thus the best adjusted
PU unit for the CD mechanism module. Changing the PU unit is thus best considered as a last resort. However, if
the PU unit must be changed, the grating should be checked using the procedure below.

• Purpose :
To check that the grating is within an acceptable range when the PU unit is changed.

• Symptoms of Mal-adjustment :
If the grating is off by a large amount symptoms such as being unable to close tracking, being unable to perform
track search operations, or taking a long time for track searching.

• Method :
• Measuring Equipment • Oscilloscope, Two L.P.F.
• Measuring Points • E, F, REFO1
• Disc • ABEX TCD-782
• Mode • TEST MODE

• Checking Procedure
1. In test mode, load the disc and switch the 5V regulator on.
2. Using the ] and [ buttons, move the PU unit to the innermost track.
3. Press key 3 to close focus, the display should read "91". Press key 2 to implement the tracking balance adjust-
ment the display should now read "81". Press key 3. The display will change, returning to "81" on the fourth
press.
4. As shown in the diagram above, monitor the LPF outputs using the oscilloscope and check that the phase differ-
ence is within 75° . Refer to the photographs supplied to determine the phase angle.
5. If the phase difference is determined to be greater than 75° try changing the PU unit to see if there is any
improvement. If, after trying this a number of times, the grating angle does not become less than 75° then the
mechanism should be judged to be at fault.
• Note
Because of eccentricity in the disc and a slight misalignment of the clamping center the grating waveform may be
seen to "wobble" ( the phase difference changes as the disc rotates). The angle specified above indicates the aver-
age angle.

• Hint
Reloading the disc changes the clamp position and may decrease the "wobble".

6.5 CD TEST MODE

- Error Messages
If a CD is not operative or stopped during operation due to an error, the error mode is turned on and cause(s) of the
error is indicated with a corresponding number. This arrangement is intended at reducing nonsense calls from the
users and also for facilitating trouble analysis and repair work in servicing.

(1) Basic Indication Method

1) When SERRORM is selected for the CSMOD (CD mode area for the system), error codes are written to DMIN (min-
utes display area) and DSEC (seconds display area). The same data is written to DMIN and DSEC. DTNO remains
in blank as before.

2) Head unit display examples

Depending on display capability of LCD used, display will vary as shown below. xx contains the error number.

8-digit display 6-digit display 4-digit display

ERROR–xx ERR–xx E–xx

11 Electricity Focus Servo NG Focusing not available.
→ Stains on rear side of disc or excessive vibrations on REWRITABLE.
12 Electricity Spindle Lock NG Spindle not locked. Sub-code is strange (not readable).
Subcode NG → Failure on spindle, stains or damages on disc, or excessive vibrations.
A disc not containing CD-R data is found.
Turned over disc are found, though rarely.
CD signal error.
17 Electricity Setup NG AGC protection doesn't work. Focus can be easily lost.
→ Damages or stains on disc, or excessive vibrations on REWRITABLE.
30 Electricity Search Time Out Failed to reach target address.
→ CRG tracking error or damages on disc.
44 Electricity ALL Skip Skip setting for all track.

50 Mechanism CD On Mech Error Mechanical error during CD ON.
→ Defective loading motor, mechanical lock and mechanical sensor.
A0 System Power Supply NG Power (VD) is ground faulted.
→ Failure on SW transistor or power supply (failure on connector).
Remarks: Mechanical errors are not displayed (because a CD is turned off in these errors).
Unreadable TOC does not constitute an error. An intended operation continues in this case.
Upper digits of an error code are subdivided as shown below:
1x: Setup relevant errors, 3x: Search relevant errors, Ax: Other errors.

- New Test Mode

S-CD plays the same way as before.
If an error such as off focus, spindle unlocking, unreadable sub-code, or sound skipping occurs after setup, its
cause and time occurred (in absolute time) are displayed.
During setup, operational status of the control software is displayed.
These displays and functions are prepared for enhancing aging in the servicing and efficiency of trouble analysis.

(1) Shifting to the New Test Mode

1 Turn on the current test mode by starting the reset from the key.
2 Select S-CD for the source through the specified procedure including use of the [SOURCE] key, and inserting the
disc. Then, press the [Jump Mode Selector] key while maintaining the regulator turned off.
3 After the above operations, the new test mode remains on irrespective of whether the S-CD is turned on or off.
You can reset the new test mode by turning on the reset start.

- Removing the OEL Unit

1. Apply hot air to the cable pins for the anode terminal using
blower used for removing a flat-packaged IC or somethin
like that. When all the pins are peeling off from the PCB
pinch the cable with a pair of tweezers and remove it slowl
from the PCB. (Fig.8)

* Be careful not to remove other electrical parts when you us

a blower. Especially, when hot air is appropriated to th
VR1902 too much, the volume will destroy.
* Flexible cable may not remove easily by transforming the
Bosses by the hot air of the Blower. Fig.8

2. Five tabs are extended until becoming straight in the direc-

tion of the arrow and then remove the Holder. (Fig.8)
3. Slowly set up the OEL Unit. At this time, the stress is pre-
vented from hanging to flexible cable in the Cathode termi-
nal. (Fig.9)
4. The Cathode terminal is removed according to the procedure
same as the Anode terminal, and the OEL Unit is removed.
(Fig.9)
5. Remove the Holder. (Remove after removing the Cathode ter-
minal without fail.) (Fig.9)

- Installing the OEL Unit

1. Install the Holder in the OEL Unit. (Fig.10) Fig.9
2. When soldering the flexible cable for the Cathode terminal
on the PCB, use a pair of tweezers. First, insert the tips of
tweezers into 2 holes in the flexible cable, then into the 2
holes in the PCB. (Fig.10)
O
3. Position the flexible cable on the PCB so that their lands
U
touch each other. (Fig.10)
4. Apply solder to each pin of the flexible cable. (Fig.10) er

* Appropriate soldering iron lightly so that the stress should

not hang to Flexible cable.

5. Lay down the OEL Unit. (Fig.10)

6. Install the Holder. (Fig.8)
7. When soldering the flexible cable for the Anode terminal on
the PCB, first, insert the Bosses on the PCB into the 2 holes in
the flexible cable. Then, take the same procedures 2 and 3 as
that for the Cathode terminal to solder the cable pins. (Fig.8)

- How to hold the Mechanical Unit

1. Hold the top and bottom frame.
2. Do not squeeze top frame's front portion too tight,
because it is fragile.

Do not squeeze.

- How to remove the Top and Bottom Frame

1. When the disk is in "clamp" state, unlock Spring A (6 Top Frame
pieces) and Spring B (2 pieces), and unscrew screws
(4 pieces).
2. Unlock each 1 of pawl at the both side of the frame,
then remove the top frame.
3. Remove the Carriage Mechanical part in such way Carriage
Mechanical
that; you remove the mechanical part from 3 pieces Part
of Damper while slowly pulling up the part.
4. Now, the top frame has been removed, and under
this state, fix the genuine Connector again, and eject
the disk.
(Caution)
Bottom Frame
When you reassemble the Carriage Mechanical part,
apply a bit of alcohol to Dampers.

3. Shift the Guide Arm Assy to the left and slowly rotate Assy
it to the upper direction.
4. When the Guide Arm Assy rotates approximately 45
degree, shift the Assy to the right side direction and
remove it.
