There are several reasons why your TV might say “no signal.” It can be frustrating, but there are ways to fix the problem.
First, check your cable box and set-top box for problems. It is common for these devices to have software loops that prevent them from properly operating.
Check Antenna
There are some reasons why your TV might say “no signal,” and there are a few simple ways to troubleshoot this problem. But first, you need to understand what the “no signal” message means and what can cause it.
A common cause of “no signal” is a poorly-positioned antenna. Antennas generally do best when pointed toward the majority of broadcast towers.
If you need help determining where to position your antenna, check your local TV broadcast station’s website for information on the direction of the broadcast towers.
If you have a TV antenna, make sure to physically inspect it for any damage or corrosion, especially on the coaxial cable and the balun/matching transformer (the device that connects the antenna to the coaxial cable).
Check Cable or Satellite Box
