I have an iMac G4 with screen issues. The CCFL's do not light up and I have replaced with several inverters with no luck. I have checked voltages and I am getting what seems to be correct from the logic board (what Apple calls a mother board). The CCFL's light only enough to be viewed in complete darkness.
While replace the hard drive today I noticed a blown inductor. I ticked it with my finger nail and it came off. Now that it is off the PCB I get NO display lighting at all.
So, with out knowing what the value of the blown inductor is (and is there anyway to figure that out), can I just replace the inductor with a jumper? The inductor has to be for the display since now I get no CCFL lighting at all. I have not checked voltages to the inverter since this happened and I guess I would worry as to why the inductor blew and if a jumper would just cause a short.
Below is a pic of where it was and then following a similar inductor.
Any help would be greatful to me.
Now that I look at this pic, I never traced the traces. The connector to the left is for the inverter cable.

The below is just a random spot on the PCB.

Again, Thank you for any help,
