Power supply section will be the first place to check, find out if you do hav 12~18vdc feeding the inverter circuits.
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 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.

Did you check the service manual troubleshooting guide yet. You can try disconnecting the power to the inverter board and see if it will stay on and have sound.

Monitor come on for a few seconds then goes black,green signal light stay on green. can you help


the monitor may be losing the back lite. take a flash light or bright light and shine it at the screen after it goes black. can you see a faint picture? if so the back lite has failed. usually the cost of replacement exceeds the cost of a new monitor but there are a couple of web sites that detail the replacement of the "ccfl" cold cathode flouresecent light.

Lg flatron blank screen


t certainly seems like the monitor is not getting a signal. Did this happen after you changed something, or just on normal boot up?
It could be the video card that has failed.
Also, check the pins on the connector; sometimes they can get pushed in.
If you can, try swapping out the video card or use the monitor on another computer.
Good luck,

Screen flashes only for a split-second (as a second display for an iMac)


The inverter is faulty.If your Monitor is powered by a mains'kettle' type lead,then it MAY be repairable,provided you can find someone to do it.If you have an external power supply,then the chances are you have a separate inverter,and it is doubtful whetther you can find the fault or a replacement circuit board....which is why we have become a throw away nation !!

Goes out


Please list the model number of your monitor.
Also is the power light flashing? What color(s)?

Unfortunately the symptoms you are describing tell me the inverter/power board inside your monitor needs to be replaced.

Bank Monitor problems


Unplug the cable from your PC, if the monitor shows a test image, the monitor is fine and the problem is with your graphic card. If you dont see nothing on-screen after unpluging the cable from the PC, then the monitor in damaged. Send it to repair.

LG Flatron L1951S-SN 19 in. Flat Panel picture problem


When the picture disappears again take a flashlight and shine it in the bottom left hand corner where the Windows Start button is located. If you can see a faint image then your back light is failing. If that?s not the case the next step would be to attach another monitor to your computer to see if the problem disappears. If it does that points to the monitor, if it doesn?t then we need to take a look at the computer itself. Let us know what you find out and please don?t forget to rate this posting.
