MY LG Monitor W2343T gos blank after a couple of minutes of displaying the desktop. I have replaced the power cable, but still same problem. If I press the red poer button it comes back and then almost immediately goes off again. I tried my PC with a difffernt miniyor and there is no probem. Please Help !

I'd try this monitor on a spare computer. It sounds like the video card (motherboard integrated or otherwise)is not putting out any video information or missing sync signals. The monitor must receive these signals or it will go into standy/sleep mode. If the computer has integrated (on motherboard) video, check your bios settings to see if it is properly enabled. If it has a slot video board, then try a different video board. Your present board might be dead. Another possibility is a bad cable connection. check the connectors for bent pins. Assuming the connector is the standard HDB-15, it is easy to bend a pin over.

Had the same problem, turned out it was due to a faulty capacitor on the inverter board, 680uF 25V (105 celsius rated). Simple to fix once you have the unit dismantled and the correct replacement part. Two screws hold the shroud on, but you need to be careful with an (old) credit card levering it off.

Unit is now working fine.

first you ensure that it is a problem with TFT or CPU. you can check it with another monitor. if it is working with another monitor then your TFT has been faulty.then you can repaired it from service center.

shaylane_195, Good description of problem! But you left out one or two key things to tell me. Age of monitor? Approximate total "ON" hours of use? Is unit covered by LG (Lucky Goldstar) warranty? You and only you can tell me if the screen is really BLANK, or is it only BLACK? Do flashlight test to determine true state of screen! Can you see very, very faint image of WIN-desktop holding bright flashlight near your black screen? This monitor works!!! You just need to fix the possible (1) "cold, frosty looking, thermally intermittant solder connection on the "internal switch-mode-power-supply/CCFL inverter board. Yes, your monitor along with many other CCFL back-lit LCD units of all brands also could have some BAD, swollen, leaky electrolytic filter capacitors installed on the SMPS/CCFL inverter board which will need to be replaced with new ones of higher quality. Get back to me, lmistyrel on aim. or do additional comment on fixya, after you do some reading in my and other fixya tech's profiles to discover all options you as consumer/user have open to you. Bye for now. 12fixlouie
