DIRECTV D10 Technical Brief - Page 3

Technician Bulletin Issue 17 2010 - 10.25.10 Diagnostic Code Issue 45-xxx Critical Satellite Data not Received Your receiver restarted at time / date because critical data could not be acquired from the satellite for 12 hours. 46-xxx Critical Satellite Data not Received Your receiver has not acquired critical data from the satellite for the past hour. Resolution / Troubleshooting 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. 47-xxx Whole Home DVR (MRV) network diagnostics (Hx24 capable only) 48-xxx Whole Home DVR (MRV) network diagnostics (Hx24 capable only) Will be reported if the network bandwidth is insufficient to meet DIRECTV specifications which points to a likely problem with the coax cables, splitters, or fittings. Will be reported if the MRV network bandwidth is being degraded due to excessive interference, as opposed to signal attenuation which points to a likely coax (scrapped together RG 59), diplexed off air signals, mixed in signals into the same coax problem with poor quality distribution from a different provider such as cable TV or MATV. 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. 49-xxx SWiM registration errors. Unable to register primary tuner. 50-xxx SWiM registration errors. Unable to register secondary tuner. (Associated with 771B OSD). 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.
