Advanced Troubleshooting

If the picture regularly breaks up, then the signal received may be too weak or too strong to allow the digital TV receiver
to generate a stable picture.
Have your service provider confirm that the signal level at the machine is 72 dBuV + / - 25 dB. This is equivalent to +12
dBmV, and includes the range of -13 dBmV to +37dBmV. These levels are acceptable for both analog and digital TV
signals.
If signal levels are not OK, you are unlikely to have good reception unless signal strength can be improved. Antenna
relocation or changes to your amplifi ers (masthead or distribution) may be indicated.
Remember amplifiers should only be used by your installer to provide the minimum necessary boost to signal strength.
Interference from impulse noise may be causing pictures to break up and audio to drop out momentarily.
Check for domestic sources of impulse noise (i.e. the use of light switches, fridges, hair dryers, air conditioner, etc.).
If present, arrange for all cables, connectors, outlets and splitters between the antenna and the receiver to be upgraded
in accordance with antenna installation guidelines. Recommends the use of quad shielded coaxial cable and F connectors.
A masthead amplifier may have boosted the signal outside the receiver's "operating window", making reception impossible.
The masthead amplifier (appears as a small box on the antenna pole within about a meter of the antenna arms) may be
able to be turned down. If your antenna is on your roof you should arrange for an antenna installer to perform this task.
