You mean that the faulty c segment can turn on also the g segment ?
By the way, if we remove the first from the left block
will the others work ?
Take care !

Its possible, but also could be the anode driver decoding.

Maybe the replaced inductor is faulty as well.

The other displays will work if one module is removed, however I am not sure if it will damage the cathode driver chip because the inductor current will have nowhere to discharge when trying to drive the removed LEDs. I think Harald had problems of this nature when developing his Classic replacement board.

I created some information about this in my Classic notes document.
