No output from left channel after crackling sound

Crackling sound commenced a week ago, & now there is no sound at all from the left channel. Re-configured the speaker setup & still occurs. Swapped the speakers around & it was still happening on the left channel. Model is SR-6200.

Marantz SR 5200/6200 lost audio or crackling on left or right channel except in mode s-direct is now fixed !
The root cause is a defective inegrated circuit on DSP board (the one with digital inputs). To fix it change the chip CS4391 by a new one or better by the improved version CS4392. On my device a capacitor was cut close to this IC : replace one 1uF after changing the IC. For any question search me with my callsing "F5RCT"; i have a spare IC for the one who is able to change it !

Does your unit have a volume knob or is it a paddle type with up and down?

Audio Output signals distorted

Without knowing what make and model of whatever you're asking about we can't be specific.
But if all outputs are distorting. Either the preamp is driving the amp too hard, or the amp is fried and needs repair/replacement.
