If I remember correctly from earlier postings, you bought a halfnut, whose internal components (display, keyboard, CPU and other chips) are integrated onto a single board -- even in the CX, I would assume. Halfnuts are generally more difficult to repair than the (older) fullnuts, although that may not be relevant to this problem.
On any HP-41, separate the case halves by removing each of the four rubber feet, along with their adhesive backing, and the screw underneath. Then, you'll be able to see how far the corrosion has spread.
If it is limited to the battery terminal contacts, one Forum participant has developed and fabricated a replacement "foil" for sale. The individual and the details can be found in Archive #15.
