Removing gum from an LCD TV screen is not an easy task. These displays consist of a soft film that is very thin and can be easily damaged. If you've already tried following your manufacturer's recommendations, or your TV is out of warranty, then this last try may be helpful. However, proceed very carefully!
Step 1. Only proceed if there is no other option and you are aware of the risks
Read the user manual and use the products and methods that are appropriate for your application. Most likely, the use of other products will lead to a violation of the warranty rules and the cancellation of the warranty.
You may want to read the Warnings section before attempting to do this yourself and remove the gum from the LCD TV screen
Step 2. Unplug your TV or power off your LCD panel
Make sure your hands are dry when turning on / off the power of the TV. Wait a few minutes for the device to cool down to room temperature before using the gum.
Step 3. Mix 1 part distilled vinegar with 1 part distilled water in a spray bottle
Do not use normal tap water, it may leave sediment on the screen.
Step 4. Apply a few splashes of the mixture onto a microfiber cloth or any soft, lint-free cotton cloth
Make sure the cloth is damp but not wet. Do not spray directly onto the LCD screen.
Step 5. Gently blot the gum with a damp cloth
Vinegar dissolves or softens it, making it easier to remove. Try scrubbing only the gum itself, not the surface of the screen.
Step 6. Rub the gum very gently as you remove it from the screen
You may need to repeat the wetting process several times to completely remove the gum from the surface of the TV. Use a new cloth or a clean area of an old rag each time. During the uninstallation process, remember not to press hard on the screen. LCD screens are very soft and pressure can ruin part of the screen permanently.
Step 7. Make sure the TV is completely dry before using it again
Do not turn it on until you are sure it is dry.
- When spraying the vinegar solution on the cloth, make sure the cloth is not near the TV.
- Do not touch the LCD screen with your fingers. You may leave greasy stains or prints on it.
- The rapid drying effect of the TV may cause streaks to appear on the screen. Make sure the TV is turned off before attempting to remove the gum.
- Paper towels and toilet paper can scratch the surface of the LCD screen, so microfiber is highly recommended.
- Damage caused by touching the screen and spraying liquid directly onto the panel may not be covered under warranty.
- Never use solvents such as acetone, ethyl alcohol and ammonia to clean the LCD screen. They are strong enough to spray onto the plastic of the screen.
- If you press too hard on the screen, dead pixels may appear.
- Review what actions might void your warranty.
- Be sure to remove any seams on the fabric you will be using on the screen, they may scratch the surface.
- Always use distilled water, not tap water or mineral water, they can leave white marks on the screen.
