TROUBLESHOOTING

Problem Solution

(1) The receiver 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

(b) Press the “Power” button on the front panel to see if the LED

display is on.

(2) Message is shown on the front panel but

no picture on TV screen

(a) Make sure the connection between the receiver and TV matches the

mode your TV should be set to. For instance, if you use a RCA cable
you may choose external video input mode in TV.

(b) Check the brightness level of your TV.

Zinwell to-do:

Add OUT1/OUT2 descriptions here.

(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 boost 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.

(7) Not all channels are available after using

“QUICK SCAN”

(a) Try "AUTO SCAN" to scan all the channels.
(b) If you still cannot get some channels please use “MANUAL

SETUP” to scan them one by one.

(8) Cannot lock signal by using “MANUAL

SETUP”

(a) Check the frequency you entered is exactly the centre frequency of

the wanted channel.

(b) Please refer to solutions in item (3) on pp. XX.

(9) No Teletext

Make sure the channel you are watching carries

Teletext information

from I-PLATE.

(10) Cannot receive channels after moving

the receiver between cities (for instance
from Melbourne to Sydney)

Please refer to pp. XX for reinstallation.

(11) RCU button pressed not responding.

Replace remote control unit batteries.
