Anyone know what Code 0 means on a digital cable box? It was working fine yesterday and woke up to this message. I have unplugged the power cord and left it off for over 20 minutes, and the code is still there...I cannot get any cable channels to work and didn't know if this means that the box needs to be replaced.
Code 0 on a Motorola box usually means it has lost it's configuration. It could be a hardware failure, or most likely a issue with your account.
Only a Comcast support agent can send the signals to get it going again. Please give them a call and see if they can communicate with the box and that your account is in good standing.
It is also possible that you are having signal issues to the box. Make sure all F connectors are snug at the back of the box, the TV outlet and any accessable splitters. Also make sure you are not routing your coax jumpers through any AC surge proector strip coax ports.
