Broken CCFL. Way to repair it? Is a LED backlight upgrade possible?

Broken CCFL. Way to repair it? Is a LED backlight upgrade possible? I got a Samsung SyncMaster 2443BW 24" monitor which has some problems. Basically it shows the picture 2 seconds after powering it on and then goes black. The repair service said that CCFLs are the problem and that a repair is expensive.
