you can easily inspect the capacitors on the display and see if they are the fauly. Now does the screen work if you connect it back to the old machine, and do any other monitors work with this computer?
can you tell me more about the symtoms of this display, what does it do when you turn it on etc?

Look for bad caps with domed tops as shown here:
If you are going to DIY and already try the monitor with another PC, 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 PRINCETON monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/

bsims77010, Tell me brand name of electrolytic filter capacitors on the large "switch-mode-power-supply / CCFL inverter supply" printed circuit board. Are any of them SWOLLEN on the end that is up ??? You can see typical "failed units if you visit YOUTUBE for video clips that show owners/tech's that replace them with new ones and now have working units again. You must tell me more about this "keeps turning off" thing???? Is unit going to "black screen" only?? Or is it going to "black n blank" screen"??? There is a difference!!! If black only then 5vdc might be ok! If "black n blank then +12vdc & +5vdc sources could be in shut down mode. Do you see screen data with aid of bright flashlight held 1 inch from the "black" screen?? Once you have knowledge of what makes "raw white light" on reverse side of your lcd panel, then you will have clue to how the new screw-in, curlie-Q style CFL light bulbs work and what an "electronic ballast" circuit is. 12fixlouie

Try looking for bad caps first, see example of failed PRINCETON monitors because of bad caps here: http://s807.photobucket.com/home/budm/allalbums

The ticking sound is from power supply turning on and off.
