What is the signal source that is connected to the TV, an antenna or a "box" of some description?
''If an antenna:''
Is it (or the antenna cable) near an electrical appliance e.g. a air-con unit, other electric motor etc? If so it may be faulty and be emitting strong EMI that is being picked up by the antenna (or cable) and causing interference to the signal .

Have you checked the antenna cable connections at both ends to make sure that they’re both OK?
-
Have you checked the strength and quality of the received signal? Usually most TVs have a signal strength and signal quality check, in the Settings menus somewhere.

It may be a faulty antenna cable connection, at either end that is degrading the strength or quality of the signal making any interference more evident
''If a "box"'':
How is it connected to the TV, HDMI, Component video, Composite video, etc?
Have you tried different inputs, input types, signal sources e.g. a dvd player, to check the display is OK or not?

Hi @sithlord ,
What is the model number of the TV?

Is the audio also affected?
What have you tried?
