Hi. Me and a friend spent part of the afternoon trying to fix his iMac with the same problem of yours. I replaced L9100 with a fuse holder and connected the LCD: the 1,6A fuse blew at once. I thought it was a lamp fault and I tried to connect just the data plug, with the same result. Guess he'll have to buy a new display...
BTW, where did you find the L9100 coil-resistor or whatever it is?
Thanks in advance.

Hello, I found your post from several years ago because I have the same problem, a short with the l9100 but in addition to that, the cooler never turns off, even with the imac turned off, and this happened from the moment the short occurred, I got the resistance coil with the same value in a damaged macbook a1478 and I already replaced it but the failure of the cooler continues, the same thing happened to you or am I a different case

Hi everyone. I have an Apple iMac A1418. Unfortunately the schematics in this thread don't show the power supply board and parts list. I need to identify MOV001 Metal Oxide Varistor on power supply model APA007. It has burnt up in a power surge and blown the onboard 5A fuse but the power supply was protected, that's the point of the varistor. I just need to replace it and the fuse and the machine will work again. Does anyone know the part type? Thanks!

There was an unexpected shutdown on the iMac A1418 820-3302 . I changed the C8371, C8372 and C8321, C8322 capacitors. The problem is gone.
