How to Solve LCD Monitor Problems

If you want to know how to solve LCD monitor problems, then you've come to the right place. LCD technology has allowed the size of computer monitors to be drastically reduced. Unfortunately, along with this new technology comes a new set of problems that didn't exist in older monitor types. Luckily, LCD monitors are fairly reliable. But, just in case something goes awry, here are some simple solutions:

Understanding LCD Technology
LCD monitors work differently from old cathode ray tube (CRT) monitors. Briefly, LCD monitors work when crystals on the inside either block or allow light to pass through a color grid to produce the images we see on the screen. Unlike CRT monitors, LCD monitors are lit by using an internal backlight, which is always running when the monitor is on.

Distorted Images
One common problem of an LCD monitor is distorted images being displayed. This is most likely caused by changing the resolution of the monitor from its native factory setting. All monitors have a preset resolution when they roll off the assembly line. Sometimes running certain programs can automatically change the monitor's resolution. If images look distorted on your screen, check the manual, find out what the factory setting resolution should be and switch it back.

Dead Pixels
Another common problem is a dead pixel. A pixel is the smallest possible point of light on your monitor. Occasionally, one will go out, causing a tiny white or black dot on your monitor to be present at all times. Unfortunately, there is no solution to this problem outside of getting a new monitor. The good news is that this is a rare occurrence, and pixels are so small that you might not even notice it's out at all.

Strange Screens
If you power up your monitor and see either a blank screen, pink screen or green screen, it could be a sign of several problems. First, check the power supply. Make sure the wires are properly connected and plugged into a reliable outlet. If you still get the same results, try hooking your monitor up to a friend's computer to see if it works. If it does, it most likely means you just need a new power supply cable, which is an easy fix, as they are available at any electronics store. If you are using a laptop, you may need to replace the LCD ribbon connector cable. You can probably order this part from the manufacturer and have a LCD repair professional replace it. This type of monitor repair is cheaper than buying a new monitor.

If the above fails to correct the problem, you may be in for heartbreak. Usually a blank screen is an indicator that the backlight on your monitor has failed. The good news is that monitors usually last about five to seven years before this happens. If it clunked out before this, check to see if your monitor is under warranty, and you can have it replaced by the manufacturer. Currently there's no easy way to replace a backlight in your monitor, unless you are an electronics whiz. Poking around the internals of a monitor is dangerous, as a monitor can shock you even when unplugged. Sadly, the only real alternative in this situation is to buy a new monitor.
