Vizio manufactures 16:9 aspect ratio widescreen televisions and 21:9 aspect ratio ultra-widescreen televisions, the latter of which are designed to play back feature films without black bars above and below the image. As with other brands, your Vizio widescreen television doesn't require much cleaning unless you touch the television or remote with dirty hands or accidentally spill a liquid or other substance on it. You simply need to dust and clean the screen at least once a week and wipe away fingerprints or spills as needed.
Turn off and unplug your Vizio widescreen television.
Remove dust and dirt from the television frame with the cleaning cloth that came with the TV, if applicable, or a dry lint-free microfiber cloth, an electronics cleaning cloth or duster.
Plug in and turn on your vacuum. Place the end of the hose nozzle a half-inch above the surface of the vents or any indented or grooved areas and vacuum up the dust and dirt trapped within the vents, indents or grooves.
Dampen a fresh cloth – wet it and then squeeze out as much excess water as possible until the cloth feels almost dry – and then wipe the entire frame again. After you're finished, wipe the screen gently with a side-to-side motion, then dampen another cloth and wipe the remote control. Dry the TV and remote control completely with a dry cloth.
Clean up a spill when it occurs – wipe away or vacuum dry spills and blot away liquid spills with an absorbent cloth and then wipe with a damp cloth. If the housing, screen or remote has noticeable marks or stains, dampen a cloth with a diluted neutral cleaning agent approved for use on LCD or HDTVs and gently wipe away the mark.
