If the installed system does not seem to be working properly, first make sure that all the cables are securely connected, then carry out the following
checks, in the order shown.

Further checks, if there is still a problem
Is anything lighted on your
set-top’s front panel?
YES
D
NO
R
Power may not be reaching your set-top.
Make sure that the power cord is properly
plugged in. If there is a switch by the wall
AC power outlet, switch it ON.
Check that the wall AC power outlet is working (for example,
by plugging in a lamp).
Does your remote control
operate your set-top?
YES
D
NO
R
Your set-top may not be turned on.
Check if the light around the POWER button
on the front panel is green. If it is not, press
the POWER button on the front panel to
turn on your set-top.
Check that nothing is blocking the path from your remote
control to the front panel.
Check that your remote control is currently set to operate
your set-top. (Consult the instructions supplied with your
remote control.)
Check that the IR Receiver setting on the Front Panel
Settings menu is set to “On” (see page 21). If it is set to
“Off”, your remote control will not operate your set-top
unless a “remote eye” (IR tether) has been attached to
the IR RECEIVE connector on your set-top’s rear panel.
This may be the case if you have a plasma HDTV that
causes interference with your remote control. To rectify the
situation, attach a remote eye, or change the IR Receiver
setting to “On”.
If your remote control will still not operate your set-top,
replace the batteries in your remote control.
Can you see a picture on
your TV screen?
YES
D
NO
R
Your TV and other equipment may not be
turned on. Check that they are plugged into
AC power outlets and turned on.
Check that you have selected the appropriate AV input
on your TV: HDMI, component video (YPbPr), S-video,
or composite video (depending on how your system is
connected up).
If you are using a component video (YPbPr) connection,
make sure the set-top’s TV Display Capability settings are
appropriate for your TV (see pages 17 through 19).
If you are using the HDMI connection, make sure the
connection goes directly from your set-top to your TV. If
your set-top detects that the link is not secure, your set-top
will not transmit a picture (see page 7). If you expect the
link to be secure, try disconnecting and reconnecting the
HDMI cable.
Is the picture distorted or
too small?
NO
D
See the next page
YES
R
Check that the TV Aspect Ratio and TV
Display Capability, as set on your set-top,
are appropriate for your TV (see pages 16
through 19). Change them if necessary.
If your TV is a 16:9 TV, you can use Auto Pillarbox to add
black borders to 4:3 transmissions, so that the picture is
not stretched (see pages 19 and 20).
If the TV Aspect Ratio and TV Display Capability settings are
correct, try using Zoom to improve the picture (see page
14) or consult the instructions that came with your TV and
try adjusting your TV’s display.
