Juno 6 Repairs

Post by em12341 » Thu Feb 02, 2017 9:37 pm

Hello everyone, I recently acquired the beautiful Juno 6 for a very reasonable price (300$). However, it does have a few issues:
- Dead keys (about every 6)
- Transpose Key doesn't work
- Square Wave LED turns on sometimes (when not pressed)
- Sticky Sliders

So far these are the only issues I've encountered. Do you guys have any ideas about repairs? Anything I could do easily on my own. I'd say my soldering/DIY experience is about a 6/10.

Thanks.

Also forgot to mention the Arpeggio seems to skip a step (usually every 4th step)

Sounds like most of those problems could be solved with a simple cleaning. The transpose button will most likely need to be replaced, and as for the square wave selector, it might be need to be replaced as well or it could be a faulty connection to the motherboard. Here's the service manual BTW: http://www.florian-anwander.de/roland_j ... ervice.pdf

Dead key is most likely a failed voice chip. Have you de-soldered ICs before?
