OBERHEIM SYNTH

Do you know that the display itself has gone, or could it be one of the driver chips or inverter that has gone (ie: the Roland MKS-70 right hand third of display is driven by a specific chip for some reason). Might be useful to check where that section of the display is powered from - might be a simple component swap out.

Subject: [oberheim] Matrix-6 display issues?

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?
