Mute Signal Circuit between Radio Receiver and Television Display Assembly [12/2019 - 10/2022]: Description

The radio and display receiver assembly controls the volume according to the mute signal from the television display assembly.

The mute signal is sent to reduce noise and popping sounds, such as those generated when switching modes.

If there is an open in the circuit, noise can be heard from the speakers when changing the sound source.

If there is a short in the circuit, even though the radio and display receiver assembly is functioning normally, no sound or only an extremely faint sound can be heard.
