OBERHEIM SYNTH

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'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!!
