      If your Toshiba CRT TV has no sound but the picture is fine, first, ensure the sound isn't muted by pressing the VOLUME button. If that doesn't work, the broadcasting station might be experiencing difficulties, so try changing the channel. Also, check if the MTS feature is in SAP mode, and if so, press the MTS button on the remote until STEREO (or MONO) mode is active.
