Fixing a Wavestation A/D that won't boot

I attempt to fix my Korg Wavestation A/D in this video. When turning it on, I only see a blank screen.
Been a while since I made a video. Tried a bit of a different style this time. I guess this is also technically a face reveal, although I've never exactly kept my face a secret.

Hope you'll enjoy it. I might have some ideas for future videos as well, maybe my channel won't go silent for another year after all.

Great video, I usually just recap power supplies that are 30ish years old or more. Those were nice Nichicons too. Electrolytics are a pain.

Nice fix! What's the synth on the top left of your desk?

That's a Virus TI2. The one I used for that Supersaw Lead at the end of the video.

it was the epoxy… when it gets old it will be able to transfer electricity instead of isolating… it starts when getting hot… you van see it at the color being dark brown… if you only removed the epoxy you had same result. mine wavestation ex had same problem

Funnily enough, I do still have the old capacitors with the epoxy stuck to them. I just measured across the epoxy, turns out it is slightly conductive. Although it's in the range of megaohms. In my case the epoxy wasn't actually in contact with anything conductive though, so I doubt this would've fixed my particular issue. Though I can see how it would cause problems if it was on other parts of the board. Good to know for future repairs either way.
