Sir, sorry reply you so late.
Please test the same signal by the both channels, the probes are the same settings (pay attention the attenuation factor), and give us a screenshot of the scope.

Sir, if you used the probe to test, please use a non-metallic tool to adjust the trimmer capacitor of the probe for the fattest square wave being displayed on the oscilloscope.

In addition, replace a connecting line to try.

Sir, please try to test other frequency signal, greater than or less than 1K.
Is there a similar problem?

Sir, could you solder?

You can try to replace a component (U100, AQY280SX).
