I have a roof antenna installed in 1986. Two days ago the TV stopped receiving the signal from Fox TV. Why?

1 Answer

Answer :

answer:Go get a whole bunch of aluminum foil for hats Dumb question number # 1 Do you have a digital convertor or a TV made in the last five years? Has the convertor been re-initiated in the recent past? Dumb question number # 2 Has the antenna twisted out of position? Try rotating the antenna to point at the city/ antenna for the Fox station. The fact that the TV station says no one else has seen a change means something at your end has changed.
