Technician Bulletin Issue 17 2010 - 10.25.10 Diagnostic Code Issue Resolution / Troubleshooting 75-xxx External Storage Error Detected. A problem was detected reading your external storage device. This test is equivalent to the tests performed for error 14/15 when using internal storage. The customer may wish to reboot the external storage device and when up and running, reboot the receiver. If the external device still does not function, it should be replaced. The receiver will revert to its internal storage once rebooted without the external device connected. Replacing receivers does not resolve this issue; it‟s normally due to a failed external drive. 76-xxx Cannot Detect Phone Dial Tone 79-xxx Whole Home DVR (MRV) network diagnostics (Hx24 capable only) 82-xxx Satellite Dish Configuration Issue. 83-xxx Satellite Dish Configuration Issue. The receiver is not networked, and no dial tone is detected. Will be reported if unexpected MRV network drops have been observed by this STB. These network drops may be due to intermittent interference and may not be present at the time of test execution. For instance if troubleshooting for 47 or 48, you may see a 79 code reported. When the 47 or 48 are resolved, the 79 code may still be reported but can be ignored. If 47 or 48 were not reported and only a 79, further troubleshooting is required. Your receiver is configured for the incorrect satellite dish. Your receiver is configured for the incorrect satellite dish. Troubleshoot using diagnostic codes 72 and 73. Troubleshoot the same as diagnostic codes 47 and 48. These tests check for valid guide data on the proper transponders and only run on non-SWiM installations. Code 82 indicates the receiver is set for a SL-5 ODU, when a SL-3 ODU is actually present. Code 83 indicates the opposite condition. Reconfigure the receiver for the proper LNB type. This issue can often be associated with the 920 OSD and missing channel remaps for the 700-1 HD premium sports programming.
