CHAPTER 1. GENERAL DESCRIPTION

[1] SAFETY PRECAUTION FOR SERVICE MANUAL

Precaution to be taken when replacing and servicing the Laser Pickup.

The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class 1 Requirements. However, the follow­ing precautions must be observed during servicing to protect your eyes against exposure to the Laser beam.

1) When the cabinet has been removed, the power is turned on without a compact disc, and the Pickup is on a position outer than the lead-in posi­tion, the Laser will light for several seconds to detect a disc. Do not look into the Pickup Lens.

2) The Laser Power Output of the Pickup inside the unit and replacement service parts have already been adjusted prior to shipping.

3) No adjustment to the Laser Power should be attempted when replacing or servicing the Pickup.

4) Under no circumstances look directly into the Pickup Lens at any time.

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

[2] VOLTAGE SELECTION

Before operating the unit on mains, check the preset voltage. If the voltage is different from your local voltage, adjust the voltage as follows.

Turn the selector with a screwdriver until the appropriate voltage number appears in the window(110V,127V,220V or 230V - 240V AC).

3. DVD SECTION

• Adjustment

Since this DVD system incorporates the following automatic adjust­ment functions, readjustment is not needed when replacing the
pickup. Therefore, different PWBs and pickups can be combined
freely.

Each time a disc is changed, these adjustments are performed
automatically. Therefore, playback of each disc can be performed
under optimum conditions.

Items adjusted automatically

1) Offset adjustment (The offset voltage between the head amplifier
output and the VREF reference voltage is compensated inside the
IC.)

* Focus offset adjustment

* Tracking offset adjustment

2) Tracking balance adjustment

3) Gain adjustment (The gain is compensated inside the IC so that the
loop gain at the gain crossover frequency will be 0 dB.)

* Focus gain adjustment

* Tracking gain adjustment

4. DVD ERROR CODE DESCRIPTION

Error Explanation

10* CAM error. Can't detect CAM switch when CAM is moving.
11* When it detect cam operation error during initialize process.
20* TRAY error. Can't detect TRAY switch when TRAY is mov-

ing.

21* When it detect TRAY operation error during initialize pro-

cess.

30 When it change to DVD function, DVD cannot start up.

* 'CHECKING'

If Error is detected, 'CHECKING' will be displayed instead of 'ER­CD**'. 'ER-CD**' display will only be displayed when error had been
detected for the 5th times.

DVD-ROM can be upgraded from CD-ROM. The write mode is
entered from the normal mode.

1. When any CD-ROM for version upgrade DVD is detected, the sta­tus informs that the version upgrade ROM is being read.

When DVD microcomputer is changed to System microcomputer
and byte 24 status data detects 0Fh:

• The TEST Mode is entered by the status reception.

• The Power button /Function switching is prohibited.

(Power supply is necessary until write is completed.)

• It is prohibited to accept any button input until write is com-

pleted.

• Change the display as follows:

TOC READ

2. To expand into RAM, DVD performs read-operation.

3. When reading ends, transmission stops for writing.

(Ignore stoppage of transmission during write.)

When transmission stops, the transmission port receives write
states, which are displayed according to port states.

2. DVD/CD MECHANISM SECTION

2.1. Replacing the DVD mechanism (See Fig. 1)

Before the replacement, unsolder the service DVD pickup short land.

2.2. How to remove DVD/CD Disc (See Fig. 2~6)

1. When DVD/CD is at play position, rotate reduction gear C clock­wise as shown in Figure 2 Until disk tray is at ‘STOCK’ position,
then rotate the gear further to eject the disk tray (Figure 6) so that
DVD/CD can be removed from the tray.

2. In another case, if DVD/CD mechanism is at tray No. 1 play posi­tion and to remove DVD/CD located in tray No. 3, the procedure is
as follows:

If the gear up down board is located at tray No. 1 position, then
rotate Reduction gear C clock-wise until Disc tray is at stalk
‘STOCK’ position. Rotate reduction gear D clock-wise (Figure 3) to
move the DVD/CD mechanism to tray No. 3 position. This is con­firmed by checking the gear up down board position Base on the
marking as indicated on the main chassis as shown in Figure 4.

• Usually changer is covered with top plate. As for reference pur­pose, we exclude the top plate for easy viewing. (Figure 5,6)

CHAPTER 6. CIRCUIT SCHEMATICS AND PARTS LAYOUT

[1] NOTES ON SCHEMATIC DIAGRAM

XL-DV484W

•Resistor:

To differentiate the units of resistors, such symbol as K and M are
used: the symbol K means 1000 ohm and the symbol M means
1000 kohm and the resistor without any symbol is ohm-type resis­tor. Besides, the one with “Fusible” is a fuse type.

• Capacitor:

To indicate the unit of capacitor, a symbol P is used: this symbol P
means pico-farad and the unit of the capacitor without such a sym­bol is microfarad. As to electrolytic capacitor, the expression
“capacitance/withstand voltage” is used.

(CH), (TH), (RH), (UJ): Temperature compensation

(ML): Mylar type

(P.P.): Polypropylene type

• Schematic diagram and Wiring Side of P.W.Board for this model
are subject to change for improvement without prior notice.
