2 TROUBLESHOOTING Phenomenon Solution
(1) The recorder front panel power indicator
doesn't light up, and no message on the
front panel
(a) Check the AC mains supply and make sure the power plug is
well plugged into a stable power outlet.
(2) Poor picture quality (a) Check the antenna and make sure it is aligned to the correct
direction. Use the recorder's "MANUAL SETUP" page to check the
signal's level and quality when aligning the antenna.
(b) If you use any kind of amplifier to boost the signal level, check
whether it works well, and ask help from the antenna installer.
(3) No sound (a) Check the recorder and your TV's volume are properly set and not
in “Mute" mode.
(b) Check the audio connectors are correctly and firmly connected.
(c) Make sure the recorder is switched to the correct aud io mode:
Dolby® Digital or PCM.
(d) Rescan this channel by using "MANUAL SETUP".
(e) Switch to other channels for confirmation on audio.
(4) No picture (a) Check whether the HD MODE Switch is set to the correct mode.
(b) Check whether your TV supports the recorder’s current video
format. Use the “V.FORMAT” button to switch the video format to
the one supported by your TV.
(c) Check the video cable(s) are correctly and firmly connected.
(d) Rescan this channel by using "MANUAL SETUP".
(e) Switch to other channels for confirmation on video.
(f) Reduce RF amplifier gain if connected to RF booster.
(5) Wrong color on screen (a) Check which connection you are using, RGB or YP
B
P
R
. Then check
whether the HD MODE Switch is set to the correct mode.
(b) Check the video cable(s) are correctly and firmly connected.
(6) Not all channels are available after usin
g
“AUTO SCAN” when installing the
recorder for the first time
Try "MANUAL SETUP" to scan these missing channels.
This phenomenon is caused by unexpected frequency offset, for
instance, in Sunshine Coast Australia, channels 47 and 65 are
transmitted on 662.625 and 788.625MHz by 125kHz offset to the
legitimate frequencies 662.5 and 788.5MHz. HDD-J35 can receive these
channels by “AUTO SCAN” most of the time, but we suggest that you
use “MANUAL SETUP” when installing the recorder for the first time.
Once the recorder picks up the signal, all the transmission parameter s
will be stored in the recorder's memory.
(7) Not all channels are available after usin
g
“QUICK SCAN”
(a) Try "AUTO SCAN" to scan all the channels.
(b) If you still cannot get some channels, use “MANUAL SETUP” to
scan them one by one.
(8) Cannot lock signal by using “MANUAL
SETUP”
(a) Check the frequency that you entered is exactly the center
frequency of the wanted channel.
(b) Refer to solutions in Phenomenon (2) above.
(9) No Teletext / Closed Caption Make sure the channel that you are watching carries Teletext / Closed
Caption information from I-PLATE.
(10) No picture when the recorder is set
to auxiliary mode (L1/L2)
(a) Make sure HDMI output connection is used for the display of
auxiliary inputs.
(b) Check the recorder’s connection to external devices (page 23).
(c) Check the video cable(s) are correctly and firmly connected.
(11) Cannot receive channels after moving
the recorder between cities (e.g. from
Melbourne to Sydney)
Refer to page 35 to reset data.
(12) The remote control does not work
properly
(a) Point the remote control at the remote sensor of the recorder.
(b) Operate the remote control within about 5m.
(c) Replace the batteries with new ones.
(d) Ensure the remote control is in STB mode by pressing the STB
button.
