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.
Power
The power is not turned on.
, Check that the mains lead 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 15) 
and switch the input selector on your TV so 
that the signal from the player appears on 
the TV screen.
, Set “LINE” in “SCREEN SETUP” to an 
item appropriate for your system (page 59).
, 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 programmes could 
affect picture quality.
, The disc is recorded in a colour system that 
is different from your TV.
, You have selected “PROGRESSIVE 
AUTO” or “PROGRESSIVE VIDEO” 
using the PROGRESSIVE button on the 
front panel even though your TV cannot 
accept the progressive signal.
, Even if your TV is compatible with 
progressive format 525p/625p 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 player is set to normal 
(interlace) format.
, If you set “LINE” to “RGB (COMPONENT 
OFF)” in “SCREEN SETUP” (page 59), the 
player outputs no component video signals.
, 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 16.
, If the HDMI OUT jack is used for video 
output, changing the “HDMI 
RESOLUTION” setting in “SCREEN 
SETUP” may solve the problem (page 58). 
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.
, Press [/1 to turn off the player, and enter 
“369” using the number buttons on the 
remote, then press 
[/1 to turn on the player 
again (page 58).
There is no picture or the picture noise 
appears when connected to the HDMI OUT 
jack.
, Try the following: 1Turn the player off 
and on again. 
2Turn the connected 
equipment off and on again. 
3Disconnect 
and then connect the HDMI cord again.
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.
The picture is black and white.
, Set “LINE” in “SCREEN SETUP” to an 
item appropriate for your TV (page 59).
, Depending on the TV, the picture on the 
screen becomes black and white when you 
play a disc recorded in the NTSC colour 
system.
, If you are using a SCART cord, be sure to 
use one that is fully wired (21-pins).
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 audio component (page 19).
, The audio component input is not correctly 
set.
