The recent FCC sales of bandwidth and ATSC 3 changes are
causing local TV channels to change numbers. Here is a handy web
site that lets you know when to re-scan so you always have the
most channels available in your area. Just type in your zip
code. LINK
Select Scan or Autotune
from your TV or converter box control menu to start the scanning
process. Your TV will do the rest. This process usually takes a
few minutes to complete.
Once your re-scan is
complete you will find your favorite stations and maybe a few
more. If you have re-scanning difficulties, you can usually find
instructions by selecting the Set-Up or Menu button on your
television or converter box remote control.
