Hey all: found out something cool today and wanted to pass it along. I have a Vizio tv and neither the cable remote or Vizio remote had full functionality(volume, channel, power). Read a forum today and tried the suggestion. I unplugged the tv from the wall and pushed/held the power button on the SIDE OF THE TV for 60 seconds. Released the power button, plugged the tv in and...both remotes have full functionality! Who knew? Don't know if this works on all TV's or not but give it a try.
