Caution to be taken when disassembling and reassembling the unit

• Disconnect the flexible cable from the main P.C.B. before disassembling the monitor assembly.
• Do not apply undue force on the flexible cable. There is a danger of breaking the cable.
• Do not touch the terminals of the flexible cable with your bare hands.
• Disassembly and reassembly should be performed in the specified order.
• Hold the LCD panel by its edges.
• Do not press the LCD panel strongly.

*If the LCD panel was pressed strongly by chance during disassembly or reassembly, leave it for about 10 seconds before 
energizing the panel.

• To clean the LCD panel, wipe with a soft colth, such as gauze, saturated with isopropyl alcohol.

* Do not wipe the LCD panel with a dry gauze.
* Never use water for cleaning the LCD panel.
* Never use the following solvents:
(ketone: acetone and others)
(aromatic compounds: xylene, toluene)
(halogenides)
* If the water splashes on the LCD panel, wipe it away immediately.

Release the lock lever and remove the battery pack in the
direction of the arrow.

1. Remove the 14 screws from the bottom of the unit.

1. Solder the 1 laser short land on the flexible cable.
2. Unlock the connectors and remove the flexible cables.

1. Reinstall the traverse assembly to the specified pin of the

unit.

2. Reinstall the flexible cable of the optical pickpup unit and

lock it securely.

3. Remove the solder of each laser short land of the flexible

cable.
Caution:

Remove the solders completely: otherwise the laser
diode won’t emit light.

4. Reinstall the spindle flexible cable as shown figure.

Make sure that the traverse assembly removed before trying to
remove the optical pick-up unit.
When removing the traverse assembly, solder the one laser
short land on the flexible cable of the optical pick-up unit.

1. Remove the two screws securing the main shaft retainer.
2. Remove the main shaft retainer.
3. Slide the main shaft in the direction indicated by the arrow

to remove the optical pick-up unit.

The optical pick-up unit is factory adjusted. Do not touch the
adjustment screw.

1. Reassemble the disassembled parts in the reverse order

of disassembly.

2. When reinstalling the traverse assembly on the main unit

after installing the optical pick-up unit, make sure to
remove the solder from each of the two laser short lands
on the flexible cable.

• Remove the solders completely; otherwise the laser diode

won't emit light.

• After replacing the optical pick-up unit, check the quality of

images played back and make optical adjustment.

1. Remove the adjustment screws A, B, and C.
2. Remove the disc motor.

1. The mounting screws of the disc motor also serve as

adjustment screws. When reinstalling the disc motor, first
turn the screws A, B, and C as far as they go by usual
force to secure them (do not overtighten).

2. Back off the adjustment screws A and C two complete

turns and secure them.

3. Back off the adjustment screw B one and a half turns and

secure them.

• This makes it nearly possible to play back disks and

adjust the jitter.
Thereafter, adjust the adjustment screws C and A as
indicated.
