LCDs are an attractive choice for many television, monitor and other screen buyers, considering the impressive image quality the devices offer. However, LCD screens are also slightly more susceptible to minor scratching than conventional screens are. But getting rid of minor scratches can be very easy and require only common household items. So stop being annoyed by that scratch in the middle of your screen and don't even think of replacing your screen before you have tried a few of these do-it-yourself options.
Make sure your LCD screen is unplugged and far away from other electrical appliances or wall outlets before beginning.
Dilute isopropyl alcohol in a 50-50 solution with water.
Dip a non-abrasive cloth into the solution and gently clean the scratched area of your LCD screen.
In the case of large cracks, fill the crack with vaseline and remove the excess with the same alcohol-soaked cloth.
Clean the surface around the scratch with water and alcohol as above.
Gently rub the scratch with a soft pencil eraser, smoothing over the antiglare coating on the LCD screen.
Clean the surface with the non-abrasive cloth.
Clean the scratched surface with water and isopropyl alcohol as above.
Apply a small amount of auto rubbing compound to the scratch and polish the scratched area with a non-abrasive cloth, gently removing the antiglare coating in the area.
Clean the area with the water and isopropyl alcohol solution.
Dry the area.
Apply clear spray lacquer to the polished area. Be sure not to spray lacquer outside of the area you polished; cover the rest of the screen with paper if necessary. Allow the lacquer to dry before turning on the screen.
Regular cleaning can go a long way in avoiding scratches and new damage to your screen, but be sure you are using the proper, non-abrasive materials when cleaning your screen. If none of the above methods works, several professional products are available for fixing scratched LCD screens. Ask about one at your nearest electronics store.
As with all cleaning or maintenance operations involving electrical equipment, make sure the device is unplugged before beginning, and that liquids do not come into contact with electrical components. Isopropyl alcohol is flammable and should be kept away from sources of excessive heat or sparking objects. Be absolutely certain that you are using a very soft and non-abrasive cloth. Abrasive cloths can scratch the sensitive surface of an LCD even more.
