(3) Poor picture quality (a) Check the antenna and make sure it is aligned to the correct
direction. Use the receiver's "MANUAL SETUP" page to check the
signal's BER and RF Level when aligning the antenna.
(b) If you use any kind of amplifier to boo st the signal level, please
check whether it works well, and ask help from the antenna
installer.
(4) No sound (a) Check the receiver 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 receiver is switched to the correct Audio mode:
Dolby® Digital or PCM.
(d) Rescan this channel by using "MANUAL SETUP".
(e) Switch to other channels for confirmation on audio.
(5) No picture (a) Check the video cables are correctly and firmly connected.
(b) Rescan this channel by using "MANUAL SETUP".
(c) Switch to other channels for confirmation on video.
(6) Not all channels are available after using
“AUTO SCAN” when installing the
receiver for the first time
Try "MANUAL SETUP" to scan these missing channels.
This problem is caused by unexpected frequency offset, for instance,
in Sunshine Coast Australia, channels 47 and 65 are transmitted on
662.625 and 788.625 MHz by 125KHz offset to the legitimate
frequencies 662.5 and 788.5 MHz. HD-S23 can receive them by “AUTO
SCAN” most of the times, but we suggest that you use “MANAL
SETUP” when installing the receiver for the first time. Once the signal is
picked up by the receiver, all the transmission parameters will be stored
in the receiver's memory.
