Static interference on your TV can inhibit picture quality, and prevent successful recording and playback of programs. Noise including lines, snow and other picture problems often require diagnostics and repair. While this isn't likely to occur at all with modern TV sets, because all signals are digital in origin, it's still possible with older sets and in some limited situations. A few straightforward tips will help you address TV static interference.

Remove Interference Sources Which Cause Static on the TV

Static on an old TV can have a wide range of sources, so the positioning of other things relative to your TV is important. Set the TV away from windows where ignition noises from motorcycles, trucks and cars can interfere. Move objects that are likely to cause static interference away from the TV. Plug hair dryers, vacuum cleaners, electric drill and microwaves in other rooms.

Secure Your TV's Connections

One of the most common causes of TV static is an issue with cords, according to TV to Talk About. This can happen with any cord, so it's a good idea to check all of them, although if you notice a problem with one component (e.g. a DVD player) but no others, it's likely that cable is the cause.

Verify that the antenna is securely attached to the TV, and if possible, install a stronger indoor antenna with a wider reception range. Confirm that all externally attached video components, such as DVD and VCR players, are correctly and securely connected to the TV. Check that your cable or satellite cord is securely connected to the TV, and that inside wall terminal leading leads to the outside wiring.

Play With Your Settings to Fix a Staticky TV

Adjust your TV's "sharpness" level. Press the "Menu" button on the remote control, then use the up and down arrow buttons to highlight "Sharpness." Verify that at minimum, the sharpness level is set at the midway point within the range. Use the right arrow button and increase the sharpness level, if necessary.

Set video noise reduction if your TV has this setting available. Press the "Menu" button" on the remote control, then use the up and down arrows to highlight "Advanced Picture Settings." Press "OK." Select "Video Noise Reduction." Select "Minimum" to display a softer picture without losing sharpness and detail, or select "Medium" for an even softer picture. A "Maximum" setting may be available; however, this setting decreases the picture detail.

How to Remove TV Static for Modern LG TVs

If you have a modern smart TV, you may expect to never experience TV static. However, for many LG TV models, the default input is the classic-style cable input, which will generate static on start-up if you don't have an input. You can change this by going to "All Settings," then "General," then "Channels," then "Channel Tuning," then "Manual Tuning" and finally "Cable DTV." Then simply turn the TV off and back on again, and it will boot in Gallery Mode instead.
