Super Gemini getting zero output

I’ve had my Super Gemini for about a month now, and have started to have some weird issues. First started with random notes holding, and then progressed to audio clicking, popping, and glitching until fizzling out into complete silence when playing the synth. And now im getting zero output entirely. Seems like a pretty serious issue here.

UPDATE: had it powered on for about 30 minutes after getting no output, and the fizzing and popping started up again randomly. both envelope lights flickering randomly as well.
