My main box and TV are working, however my 3 other TV’s keeps showing this error code. I checked the connections they are all tight. I also did the refresh and still no luck getting the other TV’s to connect! Red screens with this error code!
would you check the model number of your 'main' set top box and the other 3? (can use voice remote "about" and note the rest of the line to right of STB Version..).
had my two nonDVR-remotes go belly up - not connecting. The DVR has good signal strenth (per box diag) and it working fine. I have connected the remote directly to the "cable out" of the DVR to the "cable in" of the remote with a new comcast coax cable. I wanted to bypass the in house cabling. Should that work? Becuase it does not, what am I missing?
