Additional Information
Troubleshooting
If you experience any of the following 
difficulties while using the player, use this 
troubleshooting guide to help remedy the 
problem before requesting repairs. Should 
any problem persist, consult your nearest 
Sony dealer. (For customers in the U.S.A. 
only).
Power
The power is not turned on.
, Check that the power cord is connected 
securely.
Picture
There is no picture/picture noise appears.
, Re-connect the connecting cord securely.
, The connecting cords are damaged.
, Check the connection to your TV (page 19) 
and switch the input selector on your TV so 
that the signal from the player appears on 
the TV screen.
, The disc is dirty or flawed.
, If the picture output from your player goes 
through your VCR to get to your TV or if 
you are connected to a combination TV/
VIDEO player, the copy-protection signal 
applied to some DVD programs could affect 
picture quality. If you still experience 
problems even when you connect your 
player directly to your TV, try connecting 
your player to your TV’s S VIDEO input 
(page 19).
, You have selected “PROGRESSIVE 
(AUTO)” or “PROGRESSIVE (VIDEO)” 
using the PROGRESSIVE button on the 
front panel (the PROGRESSIVE indicator 
lights up) even though your TV cannot 
accept the progressive signal. In this case, 
select “NORMAL (INTERLACE)” so that 
the PROGRESSIVE indicator turns off.
, Even if your TV is compatible with 
progressive format signals, the image may 
be affected when you set the player to 
progressive format. In this case, select 
“NORMAL (INTERLACE)” using the 
PROGRESSIVE button on the front panel 
so that the PROGRESSIVE indicator turns 
off and the player is set to normal (interlace) 
format.
, The VIDEO OFF function takes effect.
, The player is connected to an input device 
that is not HDCP compliant (the HDMI 
indicator on the front panel does not light 
up). See page 20.
, If the HDMI OUT jack is used for video 
output, changing the “HDMI 
RESOLUTION” setting in “SCREEN 
SETUP” may solve the problem (page 79). 
Connect the TV and the player using a video 
jack other than the HDMI OUT, and switch 
the TV’s input to the connected video input 
so that you can see the on-screen displays. 
Change the “HDMI RESOLUTION” 
setting in “SCREEN SETUP,” and switch 
the TV’s input back to HDMI. If the picture 
still does not appear, repeat the steps and try 
other options.
The picture does not fill the screen, even 
though the aspect ratio is set in “TV TYPE” 
under “SCREEN SETUP.”
, The aspect ratio of the disc is fixed on your 
DVD.
Sound
There is no sound.
, Re-connect the connecting cord securely.
, The connecting cord is damaged.
, The player is connected to the wrong input 
jack on the amplifier (receiver) (page 26, 
27, 28).
, The amplifier (receiver) input is not 
correctly set.

Self-diagnosis Function 
(When letters/numbers appear in the 
display)
When the self-diagnosis function is activated 
to prevent the player from malfunctioning, a 
five-character service number (e.g., C 13 50) 
with a combination of a letter and four digits 
appears on the screen and the front panel 
display. In this case, check the following 
table.
Glossary
Album (page 62, 64)
A unit in which to store JPEG image files or 
MP3 audio tracks on a DATA CD. (“Album” 
is an exclusive definition for this player.)
Chapter (page 12)
Sections of a picture or a music feature that 
are smaller than titles. A title is composed of 
several chapters. Depending on the disc, no 
chapters may be recorded.
Dolby Digital (page 23, 84)
Digital audio compression technology 
developed by Dolby Laboratories. This 
technology conforms to multi-channel 
surround sound. The rear channel is stereo 
and there is a discrete subwoofer channel in 
this format. Dolby Digital provides the same 
discrete channels of high quality digital audio 
found in “Dolby Digital” theater surround 
sound systems. Good channel separation is 
realized because all of the channel data is 
recorded discretely and little deterioration is 
realized because all channel data processing 
is digital. 
Dolby Surround (Pro Logic) (page 23)
Audio signal processing technology that 
Dolby Laboratories developed for surround 
sound. When the input signal contains a 
surround component, the Pro Logic process 
outputs the front, center and rear signals. The 
rear channel is monaural.
DTS (page 23, 84)
Digital audio compression technology that 
Digital Theater Systems, Inc. developed. This 
technology conforms to multi-channel 
surround sound. The rear channel is stereo 
and there is a discrete subwoofer channel in 
this format. DTS provides the same discrete 
channels of high quality digital audio.
Good channel separation is realized because 
all of the channel data is recorded discretely 
and little deterioration is realized because all 
channel data processing is digital.

DVD VIDEO (page 8)
A disc that contains up to 8 hours of moving 
pictures even though its diameter is the same 
as a CD.
The data capacity of a single-layer and single-
sided DVD is 4.7 GB (Giga Byte), which is 7 
times that of a CD. The data capacity of a 
double-layer and single-sided DVD is 8.5 
GB, a single-layer and double-sided DVD is 
9.4 GB, and double-layer and double-sided 
DVD is 17 GB.
The picture data uses the MPEG 2 format, a 
worldwide standard of digital compression 
technology. The picture data is compressed to 
about 1/40 (average) of its original size. The 
DVD also uses a variable rate coding 
technology that changes the data to be 
allocated according to the status of the 
picture. Audio information is recorded in a 
multi-channel format, such as Dolby Digital, 
allowing you to enjoy a more realistic audio 
presence.
Furthermore, various advanced functions 
such as the multi-angle, multilingual, and 
Parental Control functions are provided with 
the DVD.
DVD-RW (page 8)
A DVD-RW is a recordable and rewritable 
disc that is the same size as a DVD VIDEO. 
The DVD-RW has two different modes: VR 
mode and Video mode. DVD-RWs created in 
Video mode have the same format as a DVD 
VIDEO, while discs created in VR (Video 
Recording) mode allow the contents to be 
programmed or edited.
DVD+RW (page 8)
A DVD+RW (plus RW) is a recordable and 
rewritable disc. DVD+RWs use a recording 
format that is comparable to the DVD VIDEO 
format.
File (page 62, 65)
A JPEG image recorded on a DATA CD 
(“File” is an exclusive definition for this 
player.) A single file consist of a single 
image.
Film based software, Video based 
software (page 22)
DVDs can be classified as Film based or 
Video based software. Film based DVDs 
contain the same images (24 frames per 
second) that are shown at movie theaters.
Video based DVDs, such as television 
dramas or sit-coms, displays images at 30 
frames/60 fields (24 frames/50 fields) per 
second.
HDMI (High-Definition Multimedia 
Interface)
HDMI is an interface that supports both video 
and audio on a single digital connection. The 
HDMI connection carries standard to high 
definition video signals and multi-channel 
audio signals to AV components such as 
HDMI equipped TVs, in digital form without 
degradation.
Since the video signals are compatible with 
the current DVI (Digital Visual Interface) 
format, HDMI jacks can be connected to DVI 
jacks by way of an HDMI-DVI converter 
cord. The HDMI specification supports 
HDCP (High-bandwidth Digital Contents 
Protection), a copy protection technology that 
incorporates coding technology for digital 
video signals.
Normal (Interlace) format (page 22)
Normal (Interlace) format shows every other 
line of an image as a single “field” and is the 
standard method for displaying images on 
television. The even number field shows the 
even numbered lines of an image, and the odd 
numbered field shows the odd numbered lines 
of an image.
Progressive format (page 22)
Compared to the Interlace format that 
alternately shows every other line of an image 
(field) to create one frame, the Progressive 
format shows the entire image at once as a 
single frame. This means that while the 
Interlace format can show 25 or 30 frames 
(50-60 fields) in one second, the Progressive 
format can show 50-60 frames in one second. 
The overall picture quality increases and still 
images, text, and horizontal lines appear 
sharper. This player is compatible with the 
480 (525) progressive format.

Progressive JPEG
Progressive JPEGs are used mostly on the 
internet. They are different from other JPEGs 
in that they “fade in” gradually instead of 
being drawn from top to bottom when 
displayed on a browser. This lets you view the 
image while it is being downloaded.
Scene (page 12)
On a VIDEO CD with PBC (playback 
control) functions, the menu screens, moving 
pictures and still pictures are divided into 
sections called “scenes.”
Super Audio CD (page 8)
A Super Audio CD disc can reproduce sounds 
that are extremely faithful to the original 
sound by use of DSD (Direct Stream Digital) 
technology. This technology utilizes a 
sampling frequency of 2.8224 MHz, which is 
64 times that of a conventional CD, and 1-bit 
quantization that enables the disc to hold 4 
times the amount of information that a 
standard PCM format CD can hold. Super 
Audio CDs are divided into the following 
types.
• Super Audio CD (single layer disc)
This disc consists of a single HD layer*.
*High density signal layer for the Super Audio CD
• Super Audio CD (dual layer disc)
This disc consists of dual HD layers and is 
capable of extended play over long periods.
Also, as the dual layer disc consists of dual 
HD layers on one side only, you do not have 
to turn the disc over during playback.
• Super Audio CD + CD (Hybrid disc)
This disc consists of an HD layer and a CD 
layer. Also, as the dual layers are on one 
side only, you do not have to turn the disc 
over during playback. You can play the CD 
layer using a conventional CD player.
• 2 channel + Multi-channel Super Audio CD
This disc consists of the 2 channel playback 
area and the multi-channel playback area.
Title (page 15)
The longest section of a picture or music 
feature on a DVD, movie, etc., in video 
software, or the entire album in audio 
software.
Track (page 15)
Sections of a picture or a music feature on a 
VIDEO CD, CD or DATA CD (the length of 
a song). (“Track” in DATA CD is an 
exclusive definition for this player.)
Video Index (VIDEO CD) (page 15)
A number that divides a track into sections to 
easily locate the point you want on a VIDEO 
CD. Depending on the disc, no index may be 
recorded.
