Dell E151FPp

I recently rescued a Dell E151FPp on it's way to the dumpster. Upon plugging it in, it appears that the backlight on this unit is non-functional. I was reading these two posts:

And it appears that the problem is likely just a blown fuse. Unfortunately, I have no idea which one is the problem. I can see that right next to the power socket on the power supply board there is a 2A 250v slow-blow ceramic fuse, but then there is the infamous F1 fuse next to the connector on the inverter board. Which one should I replace?

the one on the inverter, but better to test for continuity with multimeter if you can put your hands on one, If fuse blown then you will have no continuity across fuse, If multimeter has buzzer option then there will be no buzz if blown

Alright, well I finally found my multimeter and every fuse on the board is fine except that pesky smd-type "F1" fuse. Looks like I know what I need to replace.

Sometimes fuses blow for no apparent reason, but a shorted transistor can also cause it.
