No, it means the multiplexers that switch the various sliders and deliver their voltages to the ADC are working, but the ADC isn't measuring those voltages because it's blown out. I expect that when you've replaced it, lots of things will suddenly start working. When that happens, the first thing you should do is repeat at least those parts of the calibration procedure that involves sliders and other analog inputs.
