(b) Make sure the connector type between set top box and your TV set
matches each other. For instance, if you use RCA or Y/Pb/Pr
connector you may choose the same external video input RCA or
Y/Pb/Pr mode in TV set..
(c) Check the brightness level of your TV is high enough
(a) Check the antenna and make sure it is aligned to the correct direction.
Use 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.
(c) Refer to solutions in item (2) above
(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 switch to the correct Audio mode : AC-3
or PCM (MPEG/Analog Audio).
(d) Check the left and right audio channel. Sometimes the preferred
audio service is set in only left or right channel. Please refer to
"Audio setting" in user's manual.

.
(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) Scan this channel again by using "Manual Installation" and see if the
video service will come back.
(d) Check with the local TV stations. Sometimes they are just testing
new video services on their channels the video service may stop
every once in a while.
(a) Try "Manual Setup" to scan these missing channels.
This is caused by unexpected frequency offset, for instance, if the
Digital TV signal is transmitted on channel 34,but with frequency
Offset 125KHz from the original 593KHz, which becomes
593.135KHz, BRAVO HD1 can receive this channel by Auto
Installation most of the times, however, we suggest you to use
Manual Installation when first time installing the receiver. Once the
signal is picked up by the receiver, all the transmission parameters
will be stored in receiver's memory so next time you can scan these
channels by Auto Installation without any problem.
