Default Dell 2407 wfpb no backlight

Hi i got an Dell 2407 and the backlight stopped working while i was watching a movie.
The power light and input nr is on, but no backlight.
i have opened the monitor and checked the power board an i seams fine, have also checked most of the voltages and they are fine.
The fuse F1 on the inverter board is blown, and i get 19 volt on the one side comming from the connector,
so the question is what caused the F1 fuse to blow ?
I have checked all the diodes, the three big 2.5A fuses and most of the transistors, they all seams ok.
do you have any suggestions about what caused the fuse to blow, maby the 5V voltage regulstor
