I guess there is no point now risking damage to a newly working calculator. It is hard too see why a digit mid display would be ghosting due to a faulty display module. The only thing I can think of is one or more LED segments went faulty and perhaps lost some of their diode properties causing small leakage currents to flow. cheers Tony |
