How do I get rid of snowy picture on my TV? Ensure the TV is tuned to the correct channel (3 or 4) or on the right input (e.g. HDMI, Component, Video). Make sure that all of the cable connections from your wall outlet to the receiver and the receiver to the TV are secure – including any components in between (e.g. sound system).
What causes snow on a TV? The random pixel pattern is superimposed on the picture or the television screen, being visible as a random flicker of “dots”, “wavy vertical lines” or “snow”, is the result of electronic noise and radiated electromagnetic noise accidentally picked up by the antenna like air, cable, TV or CATV.
How do you fix a snow screen on an LG TV? Unplug the external component (if possible) for 30 seconds. Disconnect the HDMI cable from the TV and move it to an alternate port. Plug the device back in, and change the TV to the new input to see if the issue is resolved.
What is the possible cause if the TV screen is snowy or static? Occasionally, static, also called snow and white noise, replaces the picture and sound on some channels and can be very annoying. A snowy, poor-quality picture occurs for several reasons, including loose cable connections, interference, an incorrect input or a problem with the cable box.
