So you connect an external device and if it has audio in its outputs? If so, comment if the volume control is a button or is it also a remote control?

Cold welding: The tin used in these devices is of low quality and both the temperature variations and the vibration produced by the speakers cause some components to take off producing intermittent failures, which if not fixed in time can cause more serious problems
It happens to me that the amplifiers are placed in places where there is humidity, or water drops, sometimes glasses are placed on the device or beers are opened near it, a single drop of liquid that manages to enter until

Hello Friend. disassemble that volume and check inside the carbon lines may be cut if so, you have to change it to another one of the same number and if the lines are not cut, it may be that this dirt of the grease that it brings internally. Cheers

Then it must be the volume control that is bad. However, if the control is installed with cables from the motherboard to the same control, it may be the cable. Initially you can review the welds as these sometimes come off being very little visible to the eye this damage.
