Yes, I know about those connectors, having taken a lot of LCD devices
apart (but didn't know what they were called). And thanks for the
suggestion. I think I'll just leave it alone; the chances are that it
wouldn't work at all if I tried to rebuild it. I'm pretty sure that is
where the problem is as you suggest.
I see that my surplus catalog (Electronix.com) sells those same DVMs for
$7.95. Not worth tinkering with.
