Issue
Both of these codes result from lack of guide data
updates and are related to 920 OSDs, code 43 and
the guide displaying „to be announced‟. They can
also be associated with the conditions that result in
code 82 or 83. The box will track this lack of guide
data updates and generate a code 46 after an hour
and reboot the box after 12 hours which forces the
box to reacquire guide data at which point a code 45
will be displayed. Troubleshoot the same as
diagnostic codes 40-43.
Error codes 47 & 48 will be populated with the
[receiver name] and/or [ROUTER-„MAC Address‟] for
as many IRDs with bad connections to the network.
Start troubleshooting for the first IRD listed on error
codes 47 & 48 and rerun system test. In
troubleshooting the MRV network, verify: Green label
components BSF not used when required on STB‟s
or LNB Cabling and Connectors (including barrel and
wall); excessive use of connectors creates
attenuation and degrades the MRV network. Verify
there is nothing diplexed onto the coax – no off-air
antenna, and no CATV or MATV Splitters: every
unused output has a 75-ohm terminator (All unused
ports, including the SWiM power supply, must be
terminated); DECA‟s not used when required;
DECA‟s used on H24 / HR24 Ethernet cables
connected directly to the back of the STB Ethernet
port. A DECA BB must be installed to connect the
MRV network to the Internet.
Codes 49 and 50 are an oversubscribed SWiM
issue. Each DVR takes 2 channels and non-DVR
takes a single channel. The only workaround other
than expanding the SWiM system is for code 50
which is to put the receiver in single tuner mode via
guided setup. This will normally require an IV waiver.
