Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed LG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

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.

Hi Anand,

You need to check your power options settings and modify it , so that your monitor does not turn off automatically.


If you are using windows xp , go in control panel and then there would be an icon for power options , double click the power options and then you would find settings which read turn off monitor , turn off hard disk etc... select the turn off monitor to never mode or as per your convenience and you would have your problem solved.

Hope this helps.

My LG Flatron L1515S 15" LCD goes on blank scree(black screen) after displaying for 2 to 3 seconds and when i switch off and switch on monitor, again it is going blank after displaying for few second....


sitaramjava, Problem not new one!!! When lcd screen goes "black" point bright flashlight (torch) 1" (3-4cm) from lcd panel to determine if you can still see desk-top icons!!! If icons are visible, unit SMPS is in partial shutdown mode. If not visible then SMPS is in full shutdown mode. You or qualified CCFL back-lit lcd monitor technician will need to make repair to units internal SMPS/ CCFL inverter supply. Your monitor isn't any different than any other brand in it's basic design and operation!! Read my and other CCFL backlit lcd monitor technicians FIXYA profiles to see if you can repair it. 12fixlouie

LG monitor display problem30S.


Do you have another monitor to try? If so, swap it out and see if you have that problem.

If the other monitor works, then your LCD monitor is going bad and must be replaced.

If the second monitor exhibits the same problem, then it's your video card that is the problem.

IC POWER CM2017 LCD MONITOR


Normally when this type of problem happens, the first suspect would be the inverter board, then the filter capacitors and lastly the mainboard.
A defect in one of the lamps and faulty inverter IC may cause the display to shutdown as well. If the lamp is defective, it will send a feedback and cause it to stop producing output signal thus the display just shut off once you switch in ON.
