Your request for the exact problem will require a signal injector and use of an oscilloscope or even more test equipment. One possible cause is the contrast set to minimum.

Display Shutdown After Few Seconds To Few Minutes


Hook a spare monitor to the computer to rule out the video graphics card in the computer, and sub another video cord from the computer to the monitor if possible to check your LG monitor, If the display shuts down and power light changes colour or goes out it is a power supply board, one or more capacitors open causing the power to fail, sometimes the top developes a bulge making it easy to spot.

LG L222WS half bottom screen white


There is a problem with the capacitors in your monitor. This is a normal problem these days with flat screen monitors, I am trying to find out why it is always like tha. This will normally be caused by improper shut down or power fluctuations in your monitor. Capacitrs in your monitor are responsible for holding down the power from the supply, fr the proper display on your monitor. If a capacitor is damaged, or buldged, it no longer holds power long enough for your display, and that is why your screen goes black after a few seconds. This can be solved by opening up your monitor, using a sharp and flat object, opening it starting from the bottom working your way up until the cover is completely out. You will notice finger-like clips that are holding the two covers together. Once you are done, check on the circut board where you connect the power cable.... that is where you are going to find the damaged capacitor(s). You can identify them by noting their bulged head or if there is any liquid coming out of it. Before you replace the, take note of the polarity (+) and (-) so that whenever you replace with the new one it is in the same direction. This will fix up your problem. Note: make sure you let a Computer Technician to do this for you, unless you can do it yourself without damaging the monitor. Thank you

When i on my desktop it show blue screen and says no signal analog


That means that the monitor is not getting a signal from the computer. There are several possible issues involved. 1) Make sure that the computer tower is on. 2) Check that the video cable is connected to the active port on the desktop. (Computers often have video connections on the motherboard and an added video card. The motherboard connection is disabled when the video card is active. Similarly if there are several ports (VGA, DVI, HDMI, Display port) only one may be active.) 3) Try a new video cable (if possible) and one of the other video ports (again if possible). 4) Try connecting a different monitor to the computer or connecting this monitor to another computer.

Open up the computer and check if the card requires a separate power connection to the power supply. Make sure it is plugged in. Do the fans in the computer spin up?

If a second monitor doesn't work or the monitor works on another computer, then the problem is with the video adapter on the computer, the power supply or the power switch. Please add a comment with more information about the type of desktop and the current video graphics adapter (on the motherboard or separate card). I will provide additional help if possible.

(who has a computer in the company that needed a new monitor (power supply failed) a few months ago and lost the fan on the video card last week. Without the fan, the card overheated and shut down. Thus no signal to the monitor.)

LG Netbook x110. The screen doesnt work


You could have a faulty inverter or a CCFL lamp, To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Monitor : no display and blue led light is blinking


The power supply is the first thing that the 110v electric line goes into. The invertor is the next item past the power supply, or sometimes contained within it. I do not thing monitors are a DIY repair.      First substitute a different monitor to confirm that it is, in deed , the monitor and not the video card.
