I was touring with mine when the same problem occurred.
The synth repair man I go to for my old gear replaced all of the caps,
including the 2 big BLUE ones on the power supply board by the transformer.
but the soldering job from the original Oberheim factory was off he said,
and he showed my the holes in the plastic circuit board where the wires from the caps
come through and get soldered had enlarged, and couldn't hold the connections
for long after being tossed around from gig to gig.
* LUCKILY*,  he found me another power supply board on eBay, including the big BLUE caps,
(that look like "C" size batteries,) all in one piece and popped it in.
Everything was perfect after that.
just FYI...

      Also, I noticed that the display and voice bd use
+5VA and the CPU uses+5VB, so
probably you would want to focus on +5VA first.

I need to recap my Matrix 6 power supply

 







       

















I've
been having this problem with my Matrix 6 for a while where
the screen flickers on and off and when I am playing the
synth and this happens, the sound goes in and out too. Its
been seeming to get a lot worse recently and I need to
figure out a way to fix it! Im going on tour in a few weeks
and this is my main synth on stage.. here is a video example
of what is happening. Its kinda hard to tell that the sound
is cutting in and out too when the screen flickers, but
trust me, it does. And it is very annoying, especially
during important parts of songs!

It seems like a power supply issue,
so what should i do next to fix it I was thinking recapping
the PS. Ive never done that to a synth, but I do lots of
other electronic work so Im guessing it shouldnt be that
hard if i get the right parts. Is there a way to tell for
sure if the capacitors are bad or not
thank you for any help you can
provide!!
