Liquid Crystal Displays, or LCD monitors, are used on televisions and computer monitors, presenting an incredibly high quality of image for whoever is looking at it. However, these LCD screens sometimes malfunction, as most pieces of technology tend to do at some point, making their colors appear off, different or just impossible to look at. There are a number of reasons this may occur.
Laptop Lines, Fuzzy or Blurry Problems
Sometimes the monitors on LCD laptop screens will become blurry, fuzzy or have lines running across them. This can be due to a number of different things, ranging from physical damage to the laptop itself or just internal malfunctioning. However, one must first diagnose these problems when they occur to determine exactly what is wrong. This entails either calling technical support for your computer or trying to diagnose it yourself with the proper instructions. For example, on Dell laptop computers, the computer should be turned off, restarted with the FN key being held down on the keyboard and the PSA Diagnostics program will begin. Two color bar screens will appear in succession and if there is any distortion to either of these, this can sometimes be fixed manually without a time-consuming and sometimes costly trip to a computer repair technician.
LCD monitors used for computers or for televisions will sometimes have a bluish hue or tint to the images, which is a sign of malfunction on the LCD screen. This problem is sometimes the sign of larger internal problems inside the LCD screen itself, though it also can be easily remedied by simply checking the connections on the back of the monitor or television. Cables should be unplugged and then firmly reconnected or the connection itself on the LCD monitor may need to be screwed more firmly into place. Once this has been done, check the color on the monitor, adjusting the brightness and hue and changing to different channels or viewing different video sources to see if the problem has been remedied.
Overheating or Freezing Problems
Other extreme color malfunctions, such as a laptop LCD screen turning red upon start-up or an LCD television screen having spots of color on it permanently can be caused by a number of different physical problems. Overheating can cause the LCD screen to mis-communicate within its circuits, causing certain wrong colors to be displayed rather then the correct ones. As LCD screens do have small amounts of liquid running through them, if the screen becomes too cold the liquid can freeze and damage the LCD system, causing splotches of color to appear on screen when it becomes warm again.
