Roland JP8000 synthesizer. No audio output on the main jacks. Headphone worked, but a bit low level. I figured out that the electrolytic capacitor C219 on the main board that sits in the audio mute (reset/power up) circuit and was faulty.
After removing I could clearly see the electrolyte causing corrosion.
I removed the old SMD electrolytic capacitor, cleaned the board and replaced it by a new one. Works fine.. Here are the pictures I have taken during the repair (as always for my own purposes, but I share these with you guys).
I’m documenting repairs for my reference and yours.

There are lethal voltage exposed in electronic devices. Unless you know what you are doing, don’t try this. If you following along, you doing so at your own risk.
