Televisions models across the board can all suffer from TV static for a variety of reasons. Fixing TV static is not a job that can only be handled by an expert or professional repairman. Regardless of your familiarity with TV repairs and potential static issues, you can troubleshoot and fix static problems resulting from disconnected or loose cables and outside device interference. There are no special tools required and no hidden costs associated with attempting to fix TV static on your own.
Check the power cord of the receiver. Ensure this cord is secure within the wall outlet, power strip or surge protector, depending on your exact setup. If the receiver fails to power on while your TV is turned on, the TV will not receive a signal and will instead display all static on-screen.

Check the coaxial cable. The coaxial cable plugs into the back of your cable or satellite receiver. Ensure it is connected into the receiver's "ANT IN" port. Failure to make this connection will result in a complete lack of television signal reception on your TV, and rapidly moving white and black dots will dominate your display.
Tighten the coaxial cable. Even if the coaxial cable appears to be within the "ANT IN" port, if the cable is loose at this connection point at all it can cause partial reception problems on your TV that will result in some invasive static that ruins picture clarity. Grab the silver or golden metal band that sits near the end of the coaxial cable, close to where the cable enters the receiver's port. Rotate this metal band to the right continuously while also adjusting the band closer to the end of the cable. Continue tightening until you can no longer rotate the band further. This should eliminate static from the display.
Look around your TV's vicinity and attempt to identify any large or powerful pieces of electronic equipment that may be drawing a lot of power. Devices that draw a lot of power often give off a lot of electronic interference. These devices may include but are not limited to speakers and computers. If electronic interference is occurring, it can create static and various forms of "noise" on your TV's display that results in a poor viewing experience.
Move the powerful electronic devices to a new location that is further away from the TV. If this is not possible, move the TV itself. Failing to remove the electronics or relocate the TV will allow the display aberrations to continue. The effect may grow over time. Isolating these devices will restore normal clarity to your TV screen and eliminate static.
