How to remove scratches from an LCD TV

Scratches and Markings Can be Safely from an LCD Panel

TV’s and monitors have developed in technology in which the crispest and best pictures available can be seen on an LCD screen or monitor that is used for televisions and computers.

These screens are known to be very sensitive and any type of slight damage can have devastating results and render the item useless. Great care should be taken when cleaning or handling any type of LCD screen to keep from damage. LCD manufacturers will specify what types of cleaners and items can be used to safely clean the screen without scratching or hazing the screen.

LCD screens are composed of two glass panels that hold polarizing liquid crystals that distinguish the crisp and enhanced picture of the screen. Damage to the screen that breaks down the glass in any way and releases or leaks crystal will make the screen inoperable.

The picture will be completely lost or distorted and the screen will have been disposed of properly. If the damage to an LCD screen is minor and only surface scratches or marks are noticeable then there are ways to fix the scratches to make the unit useable.

A home remedy for light scratches will use alcohol, water and Vaseline. You will want to apply a mixture of half isopropyl alcohol and half water to a cotton ball to clean the surface of the scratch and remove any dust or residues.

Once the screen has dried, take a small amount of Vaseline and apply in the scratch. Once the scratch is filled then it will be necessary to clean residual Vaseline with an approved cleaner by the manufacturer of that screen. A small card can be used to smooth the surface of the scratch and remove excess.

A more technical approach for deep and grooved scratches can entail a bit more work. You will need auto-rubbing compound, a piece of paper, clear lacquer, isopropyl alcohol, water and a soft cloth. Clean the screen and surface with the diluted alcohol mixture, which is fifty percent of both.

Take the automotive rubbing compound and apply to the surface of the scratch. Polish the surface with the rubbing compound lightly. Take the piece of paper and make a small hole of approximately 5mm in the center. You will use this to spray the clear lacquer through and apply to the screen above the polished area. Let the lacquer dry and your screen will be as good as new.

Both techniques can be very useful in maintaining an LCD screen and preserving for as long as possible. LCD screens though have been available and the prices have dropped but are still very expensive to replace simply due to a few scratches.

They are delicate and care should be used when around an LCD screen. Game controllers and other items can easily puncture, crack or break an LCD screen and should be handled carefully. Small children and pets should be monitored around the screens and if possible prevented from touching the screen or playing too closely.

Extra care in cleaning fingerprints and smudges from the screen should be practiced and only manufactured cleaning material to be used to prevent light scratching of the screen.
