A temperature sensing apparatus comprises a temperature sensor, a current measuring device and temperature detection circuit. The method includes displaying on a pressure-sensitive display screen a processor-generated image of a vinyl record and playing, by use of a processor in communication with a processor storage, a sound encoded in the processor storage, to produce a playback of the encoded sound. A predicted-power-on instruction determines whether the corresponding component has been powered on, and powers on the component when it has not been powered on yet.
