328P #problem

Hello qcx hobbyist.

I'm asking for your help!

A friendly hobbyist has given me his broken qcx. Before I go into the error search, the error image with solution request.

qcx R / TX works. The buttons and the rotary encoder show no or partial reaction. Visual inspection showed, except too much flux on the solder joints, no errors.

328 has already been exchanged, no change.
