The Most Common Problems With LCD Monitors
A computer screen or a computer monitor is one of the most useful output devices. With the help of the PC monitor you can visually see the results of the computer’s work whether it’s a text document, an image, a movie, results of calculations or the display of various applications.
There are several problems that are typical for LCD screens:
Flashing indicator light (Apple screens)
The LED that shows the screen status may help indicating the problem of the screen. When it flashes, one knows what’s the cause of a malfunction (a technician uses this information to get to know how to approach and deal with the problem). The problem may be a fault in the charger, motherboard or inverter.
The screen doesn’t display anything.
In a situation where it seems that the screen is on but displays no image, the failure could be the power supply, the motherboard or the inverter (module that supplies current to the backlight).
The image appears and then disappears, the power indicator is still on.
If the monitor displays an image for a second or so and then disappears, the reason might be a problem with the power supply, the inverter or with one of the lamps or leds (the backlight of a screen consists of several lamps or many LEDs that provide light to the screen. The screen will light up and when it recognizes there is a problem with one or more lamps or LEDs the built in protection will turn off ALL lamps/LEDs, the image will still stay there but without the light so the screen will show “no picture”).
The screen is dead
If the screen doesn’t respond at all, the problem can lay in a power supply or the motherboard (for an example problem in BIOS program) .
See a picture but no lighting
If the screen appears to work, but the picture is very dim or can be seen only under external light (like if you were pointing on the screen with the flashlight) the backlight doesn’t work and there may be a problem with the inverter or the backlight bulbs or LEDs.
Dim backlight
The picture is displayed but not lighted enough (assuming the settings of the screen brightness are set to maximum). This problem can be generally caused by weak bulbs.
Sometimes the screen turns off
The screen is working for some time and then suddenly turns off. This is usually a power supply problem.
White screen with no picture
If you only see a white screen with no picture, it will usually be a problem in the inside cable that connects the motherboard to the screen’s electronic module. Or it also might be a problem in the screen’s module itself.
Broken screen
If the screen is physically broken or damaged we can not repair it but sometimes we can replace it.
Screen has one or more colored vertical or horizontal lines
This is usually a problem in the screen itself, and it cannot be fixed.
