Small scratches can be fixed at home.
An LCD TV is a television that uses a liquid crystal display to enable viewers to see a bright, clear image full of vibrant colors. LCD televisions are traditionally flat screen, which allows them to cut down on glare and enables a user to place them in many locations. LCD TVs can be expensive, which is why many people choose to try to fix any problems themselves before calling in the experts.
Instructions
1. Check all of the connecting wires and make sure they're fully inserted into the right slots. If one of your high-definition wires is placed into the wrong slot, your LCD TV will display a blank screen. Also check to make sure that you do actually have power going to your LCD.
2. Check the sleep-timer function on your LCD if it keeps turning off. A sleep-timer is used to turn a television set off after a certain period of time has elapsed. If the sleep-timer is not turned off, your LCD television will continue to turn itself off after a certain period of time.
3. Repair scratches by cleaning the screen with a dry, lint-free rag, then using a cotton ball to dab petroleum jelly onto the scratch. Gently rub the petroleum jelly into the scratch, then use another cotton ball to remove any residue. Do not remove the petroleum jelly that is in the scratch.
4. Replace the backlight if your LCD television is producing a dim picture, even when brightness is at 100 percent in the settings. Consult your manufacturer's manual in order to determine if you can replace the backlight yourself or if you need a professional to do it for you.
