→ Settings → SUPPORT → Sound Test
First run a Sound Test to verify that the sound signal output is normal.
If there is no problem with the test sound, check connected external devices and the
broadcast signal.
Problem Solution
Screen display is on but
there is no sound.
y
Check other TV programs.
y
Check if the audio output settings for the projector
are configured correctly.
For an analogue broadcast,
stereo is not clear or sound
comes from one speaker
only.
y
In a poor reception area (areas with weak or
unstable signals) or if multi audio is not stable,
select Mono on Multi Audio.
y
Adjust the balance using the navigation button.
TV sound is not in
sync with the image or
the sound breaks up
occasionally.
y
If the issue affects a specific TV program only, it
may be caused by problems with the broadcast
signal for the individual station. Check with the TV
station or your cable operator.
The volume changes when
I change program.
y
Volume can vary from program to program.
y
Set Auto Volume to On.
