L.5.3.3 Possible Cause: Cable From Modulation Encoder
to a Combiner/Motherboard is not connected, or
connector plug loose in socket
Check cable connectors to determine that all are plugged in and
properly seated in the printed circuit board sockets.
L.5.3.4 Possible Cause: Printed circuit board fault or con-
nector damage
These are unlikely, but careful visual inspection could show a
printed circuit board fault (short, damaged pc board trace, poor
solder joint) or a damaged connector.
Because there are eight identical Interlock Circuits on each
Modulation Encoder, it is possible to compare voltage readings
between circuits to isolate a defective component.
