LCD monitor is unlike CRT that is Cathode Ray Tube monitor in its physical appearance. Initially this LCD display is incorporated only in laptop computers whereas now the technology has advanced and extended its usage in desktop computers also. Repair of LCD monitor is easy compared to replacement of LCD components. The reason behind this is of multipurpose. LCD monitors has longer life span and extended applications. If small components fail it can be repaired.

If the main component fails replacement is best option as it is made of integrated circuits. Moreover repairing is cheaper than replacement of components. This article will help you to repair the LCD monitor on your own instead of depending on professional help. The following points require the LCD monitor repair help from expert. If the below mentioned problems exist then you are supposed to repair your LCD monitor.

When there is no power supply to LCD, if it blinks, when there is no display or white display or rainbow display, sudden shutdown of a system, stuck or dead pixel, pop up on monitor screen or some other irregular problems of color, brightness, size or position requires repairing of LCD monitor. Instead of repairing all components of LCD monitor it should be trouble shooting in a professional way to get deep in to the problem core. Endanger can either be in power supply or voltage supply.

The power supply to LCD monitor should be trouble shoot initially. Trouble shooting of LCD monitor is so easy and simple when compared to computer desktop monitors. The reason behind the simple process is LCD monitor power supply is small and compact and are outfitted with lesser number of components. The problem can either be in power plug supply or LCD monitor. Most of the modern LCD monitors are directly fixed to AC power line. As a result the transformer is not present to provide external barrier system.

This reduces the safety protection and maximizes the risk of LCD monitor damage. Whenever you work don’t fail to remove the plug from main board and supply board. Generally display monitors require various voltages for its performance. The low voltage power supply requires the AC line as input and produces DC voltages. Low voltage power supply will not allow monitor to start up immediately.

It interrupts the display mode such as brightness, color and contrast of LCD monitor display. If the LCD monitor is old it requires time to warm up during the start up process. If the system gets switched off after getting warmed up the problem may be with power button. If the resolution of system is very high LCD monitor will consume fair power supply. Similarly precise soft touch button is suitable in spite its cost and look.

The display problems like no display, white display and rainbow display may be due to error in power input. Digitally operated brightness display disturbance may be due to high brightness level set or not fine. Usually the problems are not sole dependent and are interrelated to one another. Check the settings of display mode and adjust accordingly.

The other problems of LCD monitor can be heated up quickly or vibration in joints or adequate lack in mechanical parts or soldering of component parts. Intermittent problems can be in video input power supply to LCD monitor. The components of LCD monitor should be kept clean and free from dirt and dust. This requires cleaning of LCD monitor and its integrated components using brush, soft cloth, cotton swab or vacuum supply to remove dirts.

The general tips to repair the LCD monitor is to unplug the system from the power plug and also from the computer processing unit. Place LCD monitor on a plain padded surface and unscrew them using screw driver. Some of the parts can be removed by pop out tabs. The covering shall be removed. Using the multimeter the power supply can be cross checked for its presence. The fuse shall be placed near plug or power supply cord entrance.

The fuse shall be removed from its place and tested using multimeter. The fuse shall be replaced if it is blown. In order to handle safely go through the instruction manual provided with. If the repair does not solve the process replace the components gently. The components shall be purchased from manufacturers or suppliers. Computers are not of use when there is no screen to display. Hence fix it and repair it!
