8 Trouble-Shooting Guide
Problem Possible causes Solution
Does not operate Unsuitable receiver used Receiver does not support any SCR
based on EN 50494.
No picture, no sound The antenna direction is incorrect
or
Maladjustment of receiver
(correct PIN?)
or
Insufficient operational voltage
for switching matrix (comes from
receiver)
or
Insufficient operational voltage
for LNB and accessory devices
(comes from power supply)
•
Check the signals from the LNB with
an antenna measurement device or
the satellite receiver in Quattro-LNB
mode, see point 4.1.
• Please ensure that the settings made
on the receiver are correct. SCR-LNB
mode must be set on the menu. See
point 4.6 and the instructions for the
receiver.
•
When one or more receivers can
supply power, the green LED lights up.
•
Check the LNB infeed voltage to the
TechniRouter (11.3…14 V) by
removing a cable and measuring via a
needle placed in the socket.
Assignments of the
user bands fail The level on the receiver may be
too high or too low
or
Other receivers are in operation
(this is a problem during
automatic assignment
procedures)
•
Check the satellite level calculation,
see also Calculation aid, point 8.
There should be a minimum loss of
12 dB and maximum of 45 dB (via
cable, sockets and/or splitter) between
the TechniRouter and the receiver.
•
Switch off all other receivers
Configuration OK,
the green LED lights
up, for all polarization
planes but still
nothing received Are the inputs (polarization
planes) mixed up?
How is the status of the display
LED of the TechniRouter?
•
Check the cabling
•
Traffic indicator, see point 4.6.3
Still nothing is
received Particularly with a branched
system, it is very likely that a
short circuit has taken place
somewhere in the trunk coaxial
cables between the central wire
has been caused e.g. due to
overheating.
•
Have you tested the loss as described
in point 4.1?
For the short circuit test: Separate
individual parts of the system by
extracting the trunk line plug to isolate
any potential short circuits. Be careful
to ensure that in doing so no further
short circuits (e.g. via the central wire
and casing) are inadvertently
triggered. The precise location can be
determined by resistance
measurement
