If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, 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.
Not sure about spending any money on 15" monitor.

IBM ThinkVision 17" Monitor displays for 1 second then black


This seems to be a common problem with these monitors. Have a look very closely and see if you can still see something there. From there, either send it to get repaired, or, if you are handy with a soldering iron, open it up and replace the 4 main capacitors (at least one of them will be "popped", but it is handy to replace them all.

In order to open the monitor, you will need to remove the stand, and make sure you get all of the screws out before attacking it with a screwdriver.
I have 5 IBM monitors at work with the same problem, and opening them up has shown the popped capacitors.
Again, only recommended if you know what you are doing. Screwing it up will leave you with nothing.

LCD (IBM) monitor power light is green but no display


Make sure the monitor lead which goes behind the computer is in correctly and has not come loose.

Unscrew it from the PC and put it back in again.

Monitor wont turn on, green power light on


Hi you can inspect that what's wrong with your monitors. After you turned it on and the screen went black, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so. Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,
