Here are some links to help you out..

This appears to be a quite long article, but has no pictures which makes
it not so good.

The stright bulb on this page looks like your typical ccfl lamp.

You can buy ccfl lamps at www.mouser.com or
http://www.lcdpart.com/ (they have instructions on how to do it with
pictures)

Yet another article..

Just google LCD backlight or CCFL backlight.

You can somtimes find free service manuals for whatever monitor your
working on at http://www.eserviceinfo.com/


One word of caution if your changing ccfl lamps.. They BREAK VERY EASY if
your not careful.

Mike, speaking of parts, have you found a source for inverter transformers
capable of supporting 2 19" lamps? I'm guessing the transformers will have
to be rated at about 14 to 16 watts to handle the bigger lamps. Digikey has
inverter transformers but they seem to stock only the smaller ones which are
good for screens up to 15".
Thanks, Dave
