LASER BEAM CAUTION LABEL
When the power supply is being turned on, you may not remove this laser cautions label. If it removes, radiation of laser
may be received.
PREPARATION OF SERVICING
Pickup Head consists of a laser diode that is very susceptible to external static electrocity.
Although it operates properly after replacement, if it was subject to electrostatic discharge during replacement,
its life might be shortened. When replacing, use a conductive mat, soldering iron with ground wire,etc. to
protect the laser diode from damage by static electricity.
And also, the LSI and IC are same as above.
Ground conductive
wrist strap for body.
Soldering iron
with ground wire
or ceramic type
1M
Conductive mat
The ground resistance
between the ground line
and the ground is less than 10

1.1 No power when turned on.
When the power is turned on, and if the LED on the front panel does not light green, check
the following items and repair the defective parts.
(1) Check the power supply cable
If the cable is not the supplied one, replace it with the supplied cable and turn on the
power again.
If the power supply cable is good, the AC adapter may be defective.
If the LED does not light after replacing, check the following items.
(2) Check the AC adapter
If the AC adapter is not the supplied one, replace it with the supplied AC adapter and
turn on the power.
If the AC adapter is good, the power supply boards may be defective.
If the LED does not light after replacing, check the following items.
(3) Check the Power and Play buttons

1.3 The DVD drive does not work.
When the DVD drive does not work after the power is turned on, check the following items
and repair or replace the defective parts.
(1) Press the DISC cover switch beside the Function button and turn on the
power. Then check whether or not the optical pick-up lens of the DVD drive
lights.
CAUTION: Visible laser radiation when open and interlock defeated. Do not stare into
Laser beam.
The optical pick-up lens lights dim:
It is caused by deterioration of the optical pick-up lens. Replace the DVD drive.
The optical pick-up lens does not light:
Check the connectors of the DVD-FFC. Also check the connection to the main
board and to the DVD drive.
Loose connection is found.
Repair the connection, and then check the operation of the DVD drive again.
The DVD-FFC is broken.
Replace the DVD-FFC.
Other than the above.
Replace the DVD drive or the main board.
(2) Insert a DVD disk and turn on the power
The DVD drive does not work:
The motor of the DVD drive or the main board is defective. Replace the DVD drive
or the main board.
The DVD drive works but the initializing operation of the optical pick-up lens
does not start (the optical pick-up lens operates twice), or abnormal noise
sound:
The DVD drive is defective. Replace the DVD drive.
1.4 The operation of the DVD player stops at initializing display.
If the DVD player does not work after the initializing screen is displayed, check the
indication on the screen. Then repair the defect according to it.
(1) Insert a DVD disk and close the DISC cover, and turn on the power. Then check
the LCD screen or use an external display.
The message "loading" is not displayed or the operation stops at the
message "Loading".
Since the DVD drive or the main board is defective, check the unit in the following order:
1) DVD drive
2) Main board
The message "CHECK DISK" is displayed.
Check the DVD disk for fingerprints, dirt, etc.
If the DVD disk is OK, then check the following items:
1) Check the DVD-FFC
If a loose connection, repair the connection.
If it is damaged, replace it with new one.
2) Other than above
For other cases, replace the unit in the following order:
DVD drive (defective optical pick-up)
Main board
1.5 Image output stops during the operation.
If the image output from the media in the DVD player stops during the operation, replace
the DVD drive.
1.6 No sound or abnormal sound comes out from the speakers in the DVD player.
If no sound comes out from the speakers in the DVD player, check the following:
(1) Check for moving images on the LCD screen
Check whether or not the move of image stops in halfway. If it stops, replace the DVD
drive.
(2) Check the operation of the DVD drive.
Check whether or not the DVD drive works. If it stops, replace the DVD drive.
(3) Check the connection of the speakers.
