Sound System
The protection circuitry may have operated if either of the following
conditions are noticed:
> No sound is heard when the power is turned on.
> Sound stops during a performance.
The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are “shorted”, or if speaker systems with an impedance less than the indicated rated impedance of the amplifier are used.
If this occurs, follow the procedure outlines below
1. Turn off the power.
2. Determine the cause of the problem and correct it.
3. Turn on the power once again after one minute.
Note: When the protection circuitry functions, the unit will not operate unless the power is first turned off and then on again.

What’s HighMAT
Consumers worldwide are using PCs to create their own collections of music, photos and even video by burning them onto CDs. But how these collections can be experienced across different devices can be confusing to navigate, time consuming to access for a DVD player, and be incomplete in terms of music information available to the customer.
HighMAT offers a solution to this growing consumer problem. HighMAT dramatically improves the digital media experience on consumer electronic devices by delivering a simple, standardized approach that allows consumers who have created personal collections of digital music, photography and video on their PC to:
> Create a HighMAT CD or DVD which can be easily played back on consumer electronics devices such as CD and DVD players, and car stereos.
> Move digital media files (using recordable media such as CD-R and CD-RW) between the PC and various playback devices such as CD and DVD players.

A new standard for creating personal
media on consumer electronic devices, HighMAT enable easier and more seamless
interoperability between Windows PCs and devices designed for your living room,
or the car.
When you create your homemade CDs with software that
supports HighMAT CD burning, and then play them back on a DVD player that
supports HighMAT, you get better, easier navigation. You get folders you can
access with a single click of your DVD player´s remote control. You can view
important information about your music like full song names, artist titles,
album names and genre. And you can get faster startup on your home
entertainment device. To enjoy the
benefits of HighMAT, all you need is software that supports HighMAT for CD burning
of music or photos, as well as a home entertainment device like a DVD player
that supports HighMAT for playback. Always look for the HighMAT logo on your
software or home entertainment device to ensure it supports the HighMAT
experience.
Optical Pick-up Breakdown Diagnosis
The optical pick-up self-diagnosis function and tilt adjustment check function have been included in this unit. When repairing, use the following procedure for effective Self-diagnosis and tilt adjustment. Be sure to use the self-diagnosis function before replacing the optical pick-up when "NO DISC" is displayed. As a guideline, you should replace the optical pick-up when the value of the laser drive current is more than 55.

[This unit requires no initialization
process carried out after the traditional DVD players were repaired. When the recovery measures are taken, the
customer setting will return to the factory setting as same as the
procedure described in item of
"Initialization" is carried out. Write down the contents of the
setting before recovery processing, and reset the player.] To know how to initialize the set, refer
service mode table-2.
FIRMWARE VERSION UPDATE OF THE DVD PLAYER
The firmware of the DVD player may be renewed to improve the quality
including operability and playability to the substandard discs. Processing to
optimize the drive.
> The recovery disc has also firmware version-up.
> After version-up, recovery processing is executed automatically.
> Part number of the recovery disc for version-up will be noticed when it is supplied.
Updating the firmware
> The recovery disc has also firmware version-up.
> After version-up, recovery processing is executed automatically.
> Part number of the recovery disc for version-up will be noticed when it is supplied.
Updating the firmware
1. Load the recovery disc that is
supplied to the player and run it.
2. Firmware version of the player is automatically checked. Appropriate message appears whenever necessary.
3. Using remote controller´s cursor key, select whether version updating is to be done or not. (Selection of Yes/No)
4. a. If Yes is selected, version updating is performed. b. If No is selected, only recovery is performed.
5. a. When updating is finished, remove the disc according to the message appearing on the screen. b. Remove the disc according to the message appearing on the screen.
6. Turn off the power.
Note: If the AC power supply is shut out during version-up due to a power failure, the version-up is improperly carried out. In such a case, replace the FLASH ROM IC and carry out the version-up again.

OPTICAL PICK-UP ADJUSTMENTS
Before starting optical adjustment, be
sure to take anti-static measures.
Optical pick-up tilt adjustment is needed after replacement of the following components.
1. Optical pick-up unit
2. Spindle motor unit
3. Optical pick-up peripheral parts (such as rail)
Notes: Adjustment is generally unnecessary after replacing other parts of the traverse unit. However, make adjustment if there is a noticeable degradation in picture quality. Optical adjustments cannot be made inside the optical pick-up. Adjustment is generally unnecessary after replacing the traverse unit.

Optical pick-up tilt adjustment.
1. While pressing STOP button on the main unit, press "5" on the
remote control unit.
2. Confirm that "J_xxx/yyy_zz"
(display1/display2) is shown on the front display. "yyy" and "zz" shown to
the right have nothing to do with the jitter value. "yyy" is the
error counter, while "zz" is the focus drive value. Jitter value appears on the front display.
3. Play test disc T30 (center
periphery).
4. Adjust tangential adjustment screw so that the jitter value is minimized.
5. Play test disc T30 (center periphery).
6. Adjust tilt adjustment screw 1 so that the jitter value is minimized.
7. Play test disc T30 (center periphery).
