Recently my Matrix-6 has developed a couple of dead segments on the
display; nothing major, but I would like to get it fixed. However, I
don't feel like trying to buy a whole additional display/panel board,
and Syntaur doesn't have them in stock anyway. I can try to redo the
solder connections just in case it's a cracked joint (I suspect this
is the case, since it seems to be the same segments on each
character,) but if that doesn't do it, does anybody know the part
number for the display and/or a suitable replacement part
