For the past 3 nights when we've turned on the TV that has the HR34, there's been a 776 code that says we need a hardware upgrade. Monday night, I changed channels & it went away. Last night I rebooted the DVR & it went away. Tonight, I decided to call D* about it. I have the Protection Plan so I was sent to that department. The CSR had me run a system test & it failed almost immediately saying it could not detect a SWM. He had me unscrew & reattach the cable & rerun the test -- same thing. I have an appointment for Saturday to have the system checked. I am on a SWM16 & the HR34 is on one switch with only one other receiver. I check that receiver & it had no error code. After the call, I rebooted the HR34 again & it was working once more. Whole Home works as well. What's the most likely cause -- a bad cable or a bad connection in the HR34? The cable is only 6 years old & there's nothing chewing on it in the attic. It's a direct drop from the attic to the built-in entertainment center. Fortunately, I have nothing on the DVR at the moment so I'm not screwed if they have to replace it.
