Hi,

Farnell (http://www.farnell.com) stock a range of CCFL Backlight Inverter modules for LCD panels.
Be warned, these inverters output upto 2000V.
Normally the connection to the Cold Cathode FLuorescent (CCFL) lamps uses a common plug and pinout so you should be able to interchange easily.

You need to look in the back of the monitor and see how the connectors are arranged, some boards have the two outputs at the top and bottom of the PCB, others have them in one place.

The inverter boards also have a low voltage interface that supplied power and a brightness control. Search for any information on your existing panel/inverter to locate a pinout. Then compare the pinout and connector type with the new candidate part.

Good luck.
