The Dell 2300 is a digital projector released by Dell in late 2004. The projector features a built-in XGA video card for brighter image and video projection. But like any projector, the internal fuse will burn out after long periods of use. The fuse is meant to blow or burn out when the projector runs at a higher-than-normal voltage rate. This protects the projector's internal circuitry from serious damage or shortage. Replacing the fuse in the Dell 2300 means partially dismantling the projector's casing.
