The code is a tuning error. Channels come in on different frequencies, something is impeding the frequency of those channels and maybe others. Make sure the cables are tight and in good repair, remove any unnecessary splitters and possibly have a tech out to troubleshoot further

It typically means there is a signal issue and it can't tune to it.
