Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.
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 SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/

Flickering can be a couple of different things:
Try a different wall plug, to rule out RF interference.
Replace the video cable and make sure it is not running parallel to any other cables.
If you are using VGA, use the DVI port.
Make sure you are running the monitor in it's native resolution (I think yours is 1680 x 1050) and are using the newest drivers for your graphics card. You can also try down-clocking the card and double-checking to make sure you are running the refresh rate at 60 Hz.
Unfortunately, replacing the backlight (unless you find one on eBay and do it yourself) is probably more expensive than buying a newer, bigger LCD with a faster response time.
