Hi!,
The fuse would blow if there was a short in the board or if there were a blown chip that sucked such amount of current. Even if there were no fuses, something drawing high current would get very hot, if not blown -- so you could find it very easily.
Are you sure that you measured AC voltages in the AC setting, and DCs in the DC setting of the voltmeter?
