Reception Conditions have Switched

It’s normal that the digital signals for the channels you have lost were stronger when you initially scanned than it is currently. There are several reasons why this could happen, including weather conditions, electrical interference, weak signal, and atmospheric pressure.

Faulty Coaxial Cable

Carefully check your Digital TV coaxial cable for wear, corrosion, or loose cable fittings. Avoid using a splitter, it could weaken the signal strength causing the channels to disappear. Instead, disconnect the connection from the splitter and run the cable straight from the cable box. Loose cables are another reason why you keep asking, ‘Why does my tv flicker every time? ’.

Coaxial Cable that is too long

If your TV coaxial cable length is too long (over 100-feet), more than 1/3 of the digital transmission signal could be lost. If you need a longer cable, you’ll need to install a pre-amplifier.
