Troubleshooting Guide
The Sunfi re TGP-5 is expertly
designed and built to provide years of
trouble-free per for mance. Most prob-
lems that occur can usually be solved
by checking your setup or making
sure that the audio and video compo-
nents connected to the TGP-5 are on
and fully op er a tion al.
The following information will help
you deal with com mon setup problems
you may experience during normal
use of your unit. If problems persist,
contact your Sunfi re Dealer for help.
No sound from one or more
speakers
• Speaker cables may have come
undone. Turn off your system and
check the cables, and tighten the
binding posts.
• An audio cable may have an inter-
nal break.
• The volume level is low for the
chan nels concerned. Recheck the
cal i bra tion procedure (page 40).
• The Mute switch is on.
• The channel has not been turned
on in the Speaker Size Menu
(page 38).
• The correct surround mode is not
selected. (Some DVD discs are
stereo only).
• Note: In Source Direct mode, only
the front left and right speakers are
engaged. They must also be set to
Large.
No subwoofer or poor output
• The subwoofer’s amplifi er is off, or
its controls are set low.
• Are all speakers set Large?
• SUB is not switched on in the
Speaker Size Menu (page 38).
• Recheck the cal i bra tion procedure
(page 40).
• Adjust the Crossover and check
Bass Management (page 41-42).
• See page 50 to fi nd the best loca-
tion for your subwoofer.
• If the bass is weak during Dolby
Digital or DTS playback, check the
correct audio output is selected in
your DVD menu, otherwise it may
just play stereo into your TGP-5
and you won’t get the true LFE
signal to the subwoofer.
Poor Tuning of Stations
• The antenna may be incorrectly
attached.
• Station not correctly tuned in, weak
or off the air.
• You can improve reception by us-
ing external antennas. Some cable
TV feeds also offer FM re cep tion.
The same AM station can be
heard at different fre quen cies
• One wire of the AM loop antenna
may not be connected.
• A loop antenna is required for AM
reception, as it forms part of the
front-end tuned circuit.
Full Automatic does not work
• Make sure the Fully Automatic
mode is set to ON in the Main
Zone Setup page (page 36) and
that each input is confi gured for
AUTO ON on their respective
Setup Menu pages (page 34).
In order to automatically choose the
new input source, this mode senses
the fol low ing active signals: Left audio
signals, Video signals, Digital signals
Note that LD or DVD players
sometimes put out digital signals even
when the disc is paused or stopped.
Make sure that any sources are
turned off when not in use.
If a source is always active, the
automatic operation may return to that
input as the analog audio varies. In
this case, you should try and turn off
any unused sources, or turn off the
au to mat ic mode.
If you are listening to a mono
source, make sure it connects to a left
input, or use a “Y” cord to feed both
left and right inputs.
There is no automatic selection of
the Phono input, Tuner, or 8-CH.
Certain inputs cannot be se-
lected
• Check the INPUTS menu of the
OSD (page 34), and make sure
that the input has not been dis-
abled in that particular Zone.
No TV picture
• Make sure that the video input of
your TV monitor is connected to
the Main monitor output on the
TGP-5 rear panel.
• Check the VIDEO TYPE is cor-
rect in the Inputs menu of the
OSD (page 34). Select the type of
video input you have connected, or
choose AUTO.
• Check that your TV monitor is
se lect ing it’s correct video input.
• Check the video connection from
your selected source component
into the TGP-5.
• Make sure that you are using the
same video connections. For ex-
ample, if your source is con nect ed
using S-video, then the TV monitor
must also use S-video.
• If in doubt, try connecting the video
output from your source directly to
your TV monitor. This will help you
narrow down the problem.
• Do not connect more than one type
of video connection to the same
input. Choose only the highest
quality video type.
No Holographic Image
• It is essential that your front speak-
ers are po si tioned correctly. See
pages 49-50.
• The Holographic Image is most
ef fec tive in 2-channel operation. It
gives a more ac cu rate per cep tion
of the position of musicians and
sound effects (page 48). The
results may be masked if you are
using it in a sur round mode.
