To check if a fuse is blown, first turn off the device and unplug it. Locate the fuse box, and remove the suspect fuse. Inspect the fuse visually; if the wire inside is broken or the glass is discolored, the fuse is likely blown. Alternatively, use a multimeter set to continuity mode: touch the probes to both ends of the fuse. A continuous tone indicates a good fuse, while no tone suggests it's blown.
