Why does my Optimus PROFFESIONAL STAV-3370 have no sound?

If your Optimus Stereo Receiver has no sound, there could be several reasons: * Incorrect connections: Ensure all connections are correctly made. * Mute function: Check if the mute function is activated and, if so, press the MUTING button. * Volume level: Make sure the volume isn't turned down; increase it. * Speaker wires: Verify that the speaker wires are properly connected. * Speaker selection: Confirm that either SPEAKERS A or B is selected.
