Hello Everyone, attached I have a photo of the inputs for my Rigol DS1054. Every channel but channel 1 seems to be working in order. Channel 1 is very wonky. What would be the best course of action for a repair? Opening up the oscilloscope probing the inputs, or could it be a firmware issue? I will be doing both, but im just wondering if someone before me had this problem and could share a little bit of wisdom.
