Please pay attention to your surroundings and repair safely.

2. Adjustments

To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification.
Adjustments should be performed in accordance with the procedures/instructions described in this manual.

4. Cleaning

For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper
cleaning should be performed to restore their performances.

• For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs
accompanied by reworking of soldering.

• Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 ºC.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 ºC in general, although
the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of
the soldering iron.

Do NOT use a soldering iron whose tip temperature cannot be controlled.

Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting
temperatures (hard to melt/easy to harden).

The following lead-free solders are available as service parts:

• Parts numbers of lead-free solder:
GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.

1. To replace the MAIN PWB Unit, perform the items 9 - 12 of “8.1 UPDATING SOFTWARE” and confirm the version: it is neces­sary to update with a disc to the latest version if the MAIN PWB Unit version is old.

2. The IC7201 and IC8505 cannot be replaced because they have the BD-playback key already written. Accordingly, the IC8502
that has the software written together with the IC8505 cannot be replaced either. Keep also in mind that the IC8503 cannot
be replaced either because of the model information on it.

Be sure to do set to left side. If it is right side, wouldn't do normal operation.

About the JPEG file format

JPEG is a type of file format for storing still-image files
(photos, illustrations, etc.). The Player lets you play JPEG
format still-image files.

File formats that are not compatible.

Still images in formats other than JPEG (such as TIFF)
cannot be played.
There may be some files that cannot be played even if they
are in JPEG format.
Progressive JPEG files cannot be played.
Moving image files and audio files as well as Motion JPEG
format files cannot be played, even though they are JPEG
files.

Other files that cannot be played back.

You may not be able to play some still images which you
have created, touched up, copied or otherwise edited on
your computer.

You may experience one or more of the following
symptoms when playing files.

It may take some time to play files depending on the
number of folders, number of files and volume of data
involved.
EXIF information will not be displayed. EXIF stands for
Exchangeable Image File Format, and is a standard for
storing interchange information in image files, especially
those using JPEG compression. (Refer to http://exif.org for
more information.)

When using the unit to play a CD-RW/-R disc
with still images stored (recorded).

Discs that are not formatted in music CD format, or discs
containing mixed media (for example, music, videos, and
still photos in jpeg format) may not be playable. You may
not be able to play some of these discs at all.
Multi-session discs cannot be played.
You may not be able to play some still images you have
processed (rotated or saved by overwriting other images)
using image processing software or some still images you
have imported from the Internet or e-mail.

Discs with unusual shapes cannot be played.

Discs with unusual shapes (heart-shaped or hexagonal
discs, etc.) cannot be used. The use of such discs will
cause malfunction.

The following BD-RE/-R, DVD-RW/-R and
DVD+RW/+R discs cannot be played.

Discs on which data has not been recorded cannot be
played back.
Pioneer cannot guarantee playback compatibility for all
self-recorded BD-discs because Blu-ray is a new and
evolving format. The playback compatibility will be affected
by your choice of BD-recorder, BD-disc and BD-burning
software. Please always ensure you are using the latest
software versions on all units and contact the individual
manufacturers for further help if required. To avoid
inconveniences, please check the playback compatibility of
your self-recorded disc before you purchase this BD-player.
For maximum playback compatibility of self-recorded
BD-discs Pioneer recommends that the BDMV/BDAV
standards are used. If a playback issue occurs after
purchase, please download the latest software version for
your BD-player from the Pioneer internet page or ask your
Pioneer-Dealer. This BD-player uses the latest technology

Dolby Digital

A sound system developed by Dolby Laboratories Inc.
that gives movie theater ambience to audio output when
the Player is connected to a Dolby Digital processor or
amplifier.

BD Video

Enjoy BD-specific functions including BONUSVIEW (BD-ROM
Profile 1 Version 1.1), such as picture-in-picture, and BD-LIVE.
For the BD video discs compatible with BONUSVIEW/BD­LIVE, you can enjoy additional contents by copying the data
from the discs or downloading it via the internet. For instance,
this function is capable of playing the original movie as the
primary video while playing video commentary from the film
director on a small screen as a secondary video.

NOTE

The available functions differ depending on the disc.•

Title, Chapter and Track

Blu-ray discs and DVDs are divided into “Titles” and
“Chapters”. If the disc has more than one movie on it, each
movie would be a separate “Title”. “Chapters”, on the other
hand, are subdivisions of titles. (See Example 1.)
Audio CDs are divided into “Tracks”. You can think of a
“Track” as one tune on an Audio CD. (See Example 2.)

Example 1: Blu-ray disc or DVD

HDMI cable holder on the rear of the main unit

This Player comes with a dedicated cable holder so that the
HDMI cable does not place direct weight and stress on the
terminal. When connecting the HDMI cable, be sure to pass the
cable through the cable holder and secure it.

CAUTION

Do not pull on the HDMI cable when it is connected to the terminal, as
this can damage the terminal or cause a poor connection.

•

Press down on the tab and pull it towards you.
Pass the HDMI cable (commercially available) through the

cable holder.
Press in on the tab until it clicks into position.
