ALso, check all the cables to make sure that they did not fry or melt. THey will be easy to recognize.
There are several different boards in a monitor, power, inverter, and VGA. Sounds like you might have an issue with the VGA baord, though since it connects to the other boards, the problem could be anywhere.
Perhaps someone with more Lilli experience will chime in.
If you don't know what a continuity test is, the read up, or take it to a professional. If you don't have a tester, the same thing applies.
