Technician Bulletin Issue 17 2010 - 10.25.10 Diagnostic Code Issue Resolution / Troubleshooting 51-xxx SWiM registration errors. Receiver is configured for SWiM but cannot detect SWiM. (Associated with 771A OSD). Look for a faulty SWiM power inserter, a power inserter on a switched electrical outlet or anything inline that will not pass or attenuates the 2.3 MHz control channel. These can often be non-DIRECTV approved splitters added by the customer or long cable runs. These issues can often be intermittent. An accidentally attached b-band converter can also result in a loss of SWiM communications. 70-xxx Cannot Detect Home Network 71-xxx Cannot Detect Internet. 72-xxx Cannot Detect Phone Dial Tone 73-xxx Cannot Detect Phone Dial Tone Your receiver is configured to work with a home network, but the network was not detected. Please check the network cabling and equipment. Select "Test Again" to see if this has solved the issue. Communication problem between receiver and home network or router. Your receiver detects the presence of a home network, however it cannot access the Internet. If your network does have a broadband connection present, this may be due to the receiver not obtaining a DNS entry during DHCP negotiation with your home network. The receiver is connected to the Internet, but no dial tone is detected. The receiver was previously configured for a network, but the Internet and the dial tone is not detected. A 70 or 71 will also be present. Terms: Home network = Customer‟s router or ISP modem. DNS = Domain Name System. It translates domain names into an IP address that can be used by the DIRECTV receiver or computer. DHCP = Dynamic Host Configuration Protocol. It gets parameters needed to operate in an IP network. Restore Network Defaults. It doesn't restore entire receiver settings only resets the network settings for Internet communication: After receiver resets to network defaults: Select "Connect Now." Select "Test Connection" to make sure your receiver can connect to your network and the Internet. This is a basic dial tone test. Check for a poor phone line connector and that the phone line is plugged into the correct jack. Test the phone line on a spare nonpowered phone. Access the hidden menu using the menu and right arrow and run the modem test. Note that if a diagnostic code 72 is displayed, this should only impact caller ID since PPV details are reported through the Internet. 74-xxx Dish alignment test not run.
