Table 5-1 Audio Troubleshooting Procedures
Symptom Possible Cause/s What an authorized installer can do
Distorted
audio at normal
volume
levels
1. Input level
too high.
2. Defective/
incompatible
speaker.
3. Volume control
miswired.
Reduce level settings in VIA!TOOLS or ELANTOOLS.
a. Check for physical damage to speaker.
b. Ensure speakers have an appropriate power rating for amp.
Check for proper input/output connections at volume control.
Input comes from amplifier, output goes to speakers.
Hum in
speakers
when audio is
not present.
Ground loop. Plug all sources into same AC outlet.
Test AC outlet using ground tester.
Table 5-2 VideoTroubleshooting Procedures
Symptom Possible Cause/s What an authorized installer can do
No video to tv
monitors or
VIA! Touch
Panels
1. Source not
playing.
2. No source
selected in
zone.
3. Wiring;
video inputs
and/or outputs
incorrectly
connected.
4. Programming;
video
inputs and/or
outputs incorrectly
programmed
.
Press Play, Tune station etc.
Select source on front panel, keypad, or other zone controller.
Verify and correct wiring.
Verify and correct programming.
Video image
is not optimal
( ie., smeared,
ghosted,
blurry, or
dull).
1. Wiring; inhouse
coax
runs picking
up noise from
high voltage
lines etc.
2. Wiring; coax
has sharp
bends or poor
quality wire.
3. Source output
too high.
Certain satellite
receivers
have especially
high output
Do not run video cables near AC lines. Cross AC lines at 90
degrees.
Make gradual bends in coax when running wire. Use high
quality wire.
Use an RCA ‘Y’ cable with a 75 Ohm terminator connected to
one leg. This will reduce the source output strength.
