Assignee: D&M HOLDINGS, INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 11:
12. An audio-visual device of an audio-visual system, the audio-visual device supporting a solution of a fault occurring in the audio-visual system including the audio-visual device, comprising:
an input and output interface for an audio-visual signal;
solution support program storage unit for storing, for each potential fault of a plurality of potential faults, at least one solution support program for supporting a job of a user for solving the each potential fault occurring in the audio-visual device and in the audio-visual system;
fault determination means for determining a fault of the plurality of potential faults based on information acquired through the input and output interface;
a control unit for determining a solution to the fault of the plurality of potential faults based on the information acquired through the input and output interface, wherein the solution is one of the plurality of solution support programs; and
a man-machine interface configured for:
outputting a message for prompting the user to conduct a predetermined job, and
outputting a message for prompting the user to form a loop by connecting a cable between an input interface and an output interface for the audio-visual signal,

wherein the control unit inspects input from the input and output interface and inspects output to the input and output interface when no fault is determined by the fault determination means.
