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
or
Insufficient operational voltage for
switching matrix
(comes from receiver)
or
Insufficient operational voltage for
LNB and accessory devices (comes
from receiver or optional 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
