Google is your friend, Frank :) I posted how I fixed the one in my Star
Wars a couple years ago. I used a copper window defrost repair kit from
the local auto parts house. At the time everyone was using silver
conductive paint pens but man those are expensive! The copper paint is
absolutely conductive enough for the displays. I didn't have to expose
the broken lead. Dude, it's already exposed! Believe me, the glass
doesn't suddenly melt in over the top where they break off so no
grinding needed. All I did was scrape with a tiny jewelers screwdriver
to clean the broken leads. I could see them shiny under a mag glass.
Then I pretensioned the good leads so they would have pressure against
the glass at rest. Now I used a toothpick and dropped the copper paint
at each joint and let dry overnight. The next day I carefully plugged it
in and by golly all lines were back. At this point I needed it to be
sturdy so I used drops of super glue at the joints and built it up with
about 3 or 4 drops on each one. My start wars is still chugging along
today just fine :)

I have a very nice and bright DMD with 4 lines out due to broken
traces and I figured I have nothing to lose trying to fix it. I know I
can just buy a new one, but what kind of challenge is that ;)
I spent sometime last night followingwww.txpinball.com/fixing_DMD_displays.html.
This is a great tutorial, but I noticed the data east DMD I have
(128x32) has the traces at the bottom of the glass, not at the middle
like in the tutorial. This makes it very difficult to get the dremel
tip down at the bottom to grind away and expose the leads. Perhaps
they have a very tiny grind tip?
Has anyone had success fixing broken traces on Data East DMDs? If it's
possible I'll try again since I have nothing to lose aside from time
and my temper :)

Sounds like a good way to go, no grinding
I tried the grinding method pushed a bit too hard and I ended up with
a crack right across the DMD.
