Re: DC504 counter display

If these are socketed, first try wiggling the individual displays in the socket, then try swapping a known good display for an apparently defective display.
I've known these displays to lose a segment. ?I've also known driver lines to go bad. ?Swapping the display will diagnose both problems.

I wasn't clear in describing my symptom. 5 of the 7 digits are OK; they display an "8" when you hold the reset button. One digit has a bad center horiz segment; another digit has a bad top horiz segment.
Does that change anyone's diagnosis?
