Hi everyone
we need a bit of advice on this ...
this is an HP-65 display board the behaves like this no matter what logic board
we use, since the same logic boards are working fine in their own units we
assume that is the display board with some problems :
beside an obvious degradation of the first left led block,
for every digit lit (except when the number 2 is shown) it also lits the
next h segment (decimal point) and the next c segment.
What could it possible be and what could we possibly check ?
Thanks in advance !!!
