If the audio sound is not output, the
multivision display may have a problem. In addition, if any of the speakers
or tweeters is short-circuited, the protection circuit inside the
multivision display disables all the speakers or tweeters to sound.
Therefore, if all the speakers do not output sound, the speaker or tweeter
circuit may be shorted or the speaker or tweeter may be defective.
