We will go over the diagnostic code meanings and how to resolve the issue prompting the code to appear. Any comments or questions about this document should be sent to: [email protected] Diagnostic Codes Diagnostic Code 10-xxx Receiver error detected. 11-xxx Receiver error detected. 12-xxx Receiver error detected. 13-xxx Receiver error detected. Issue A problem with your receiver was detected. A problem with your receiver was detected. A problem with your receiver was detected. A problem was detected reading your access card. Please check to see that the card is inserted correctly and rerun the test. Resolution / Troubleshooting Both of these indicate receiver errors that are not recoverable in the field so the box must be replaced. Code 10 indicates a RID-related error while 11 indicates the tuner hardware can‟t be accessed. The presence of error 11 may also result in a box stuck in step 1 of 2 at boot up. This indicates no signal on the network tuner in MPEG4 boxes. This tuner is DC blocked and slaved to the primary tuner and is used for guide and conditional access data. If the primary tuner shows good signal strength with this error present, then the box should be replaced. This is often associated with a 761 / 762 OSD. It can be a card inserted incorrectly, a faulty card reader in the receiver or a faulty access card. Reposition the card and swap between boxes to isolate the cause. Note that brown discoloration of the CAM card on top does not indicate a failed or about-to-fail CAM card.
