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.

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
         Press the POWER button or the PLAY button on the DVD player. If the power does
         not turn on, check the following:
               Check the connector of the switch unit in the DVD player.
               (If the connection is loose, repair the connection.)
               Replace the switch unit and turn on the power again.
               If the LED does not light after replacing, check the following items.
     (4) Replace the main board
1.2 The initial screen is not displayed on the LCD.
    If the initial screen is not displayed on the LCD, check the following items.
    (1) Check the LED on the front
         If the LED does not light, proceed to 1.1.
    (2) Check the backlight
         If the backlight does not light up, separate the DVD player into top assembly and
         bottom assembly, and check the LCD harness and the connectors for
         defects.
         If the connector harness is broken:
             Replace the broken harness.
         If the connector harness is not broken:
             Remove the LCD cover and plate of the LCD unit and check the following:
                Check the connector of the FL harness, repair connectors.
                If the connectors are good, replace the FL inverter or the LCD.
    (3) Check the lighting of LCD
         If the LCD does not light, separate the DVD player into the top assembly and bottom
         assembly, and check the LCD harness and the connectors on the main board.
         If the connector is broken:
             Replace the LCD harness or the main board.
         If the connector is not broken:
             Remove the LCD cover and plate of the LCD unit, and check the connection to the
             harness of the LCD unit.
                If a bad connection is found.
                Connect the LCD harness to the LCD unit.
                Other than the above
                Replace the LCD unit or the main board.
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.
         Separate the DVD player into the top assembly and bottom assembly, and then check
         the connection of the speaker harnesses to the main board. If a bad connection, repair
         the connection.
         Other than the above, replace the speakers or the main board.


1.7 No image or sound comes out from the external output
    If any image or sound is output from the TV connected by the external cable, replace the
    main board or the connector.
      NOTE: Before this test, make sure the drive works properly.


1.8 No sound comes out from the headphones.
    If no sound comes out from the headphones, replace the main board or the connector.


1.9 No image or sound is output by the external input.
    If any image or sound is output by external input, replace the main board or the connector.


1.10 The DVD drive does not operate with the battery.
    (1) Check the operation with a good battery.
        Install a good battery and make sure the LED lights up orange while the AC adapter is
        connected. When the LED does not light up or blinks, check the connection of the
        battery harness inside the DVD player. If the connection is loose, repair connection. If
        the harness has been connected firmly, replace the main board.
    (2) Other than the above, replace the battery.

        NOTE:
           For this check, use a battery which is not fully charged (because the LED does
