Monitor comes on for a split second, then goes to black
I have an LG L194WT 19" Flatron monitor. I sold it on eBay (it was working fine) but the buyer got it and told me the screen blacked out after 1 second or so. He returned it and it's doing the same thing to me. The power stays on, but the monitor blacks out. He said he tried it on multiple computers. When I turn the monitor off and back on, it comes on for a brief second then goes off again.

This is a problem with the capacitors in many different monitors. I have 5 IBM ThinkVision monitors sitting on my desk at work with the same problem.
If you know what you are doing, pop the monitor open and have a look at the powerboard inside it. There are four main capacitors, and its likely one or 2 will be popped. Get some replacements, solder them in and you're set.
Again, only if you know what you are doing. $3 of capacitors is cheaper than $50 repair.

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,
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 !!
Same problem started happening two days ago and ever since. I called LG and the product falls under a 3yr product warranty according to them (from my original purchase date of January 20, 2007). They will send packing slips to me so I can send the defective unit back to LG. I was told I am eligible for a replacement monitor - which will be shipped to me within 10 to 14 days (consecutive days, not business) - although I'm not sure what I'm being sent in return. My suspicion is that this monitor issue is a known issue by LG and they are quietly replacing the unit to those who follow through by calling CS.
Tips: Have your original purchase date on hand (in the form of a receipt) just in case they want proof of purchase.
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.
