How to Fix an LCD Chip

LCD technology is used in large-screen televisions and computer monitors. LCD screens are usually fairly resilient, but LCD monitors don't have a glass sheet covering the main display, as did the older CRT (cathode ray tube) televisions. This makes them weaker and more prone to cracks and scratches. The best way to avoid damage is to look after your set and clean it with a soft cloth. If chips do develop, however, they can be repaired with some basic equipment.

Skill level:

Things you need

  • Soft cloth
  • Petroleum jelly
  • Cotton balls

  1. 1

    Wipe the surface of the screen with a clean, soft cloth. Make sure there is no dust or debris left on the LCD screen since this may become trapped in the chip during the repair process. Many plasma and TV sets come with a cleaning cloth, so use this if you can find it.

  2. 2

    Squeeze some petroleum jelly onto a ball of cotton. The amount of jelly will depend on the size of the chip, but generally a blob the size of a dime should be sufficient.

  3. 3

    Press the cotton ball into the chip in your LCD screen so the petroleum jelly sinks into the chip. The density of petroleum jelly is similar to that of the technology used in LCD displays, making it an ideal filler for cracks and chips.

  4. 4

    Use a clean cotton swab or soft cloth to rub away any excess vaseline that goes on the LCD screen outside the chip. Don't use a putty knife or sharp object to clean away the vaseline or you may scratch the screen.

Tips and warnings

  • Don't use tap water when cleaning away smudges from your LCD screen. Tap water contains chemicals, such as chloride which can leave marks on your LCD screen.
  • Only use soft cloths to clean your LCD screen. Paper towels and rough, old cloths can be abrasive and cause scratches on your LCD monitor.
