I started a new topic on this as the other one by a different person "Roland Juno 2 Won't Power On" has been solved. I believe my problem is different.
I basically have a Roland Juno-2 that has never been opened. I open a lot of synths and I can tell I'm the first one to crack it open. The Juno-2 is in excellent condition all around. When you flip the power switch it's completely dead. No flicker, no heat, nothing. It's like the power doesn't even get to first base. I do try to repair my own synths, however I usually leave the Power supply area alone. Inside the Juno-2 seems pretty basic, so I thought I would scout around and see if I could find the problem.
I opened up the synth and inside everything seemed clean and connected. The power cable was fine, the switch looked good, along with everything else...BUT... the Electrolytic Capacitors looked funny to me on the Power Supply Board. Usually if they are bad I notice a bulging at the top, however the three capacitors on the power supply board look fine on top. The bottom however look like they could either be leaking or perhaps surrounded by a glue of sorts. I'm not sure which, although my guess it's a leak. It's kind of dull and crusty while glue is usually shiny and smooth.
My thoughts are that if the Electrolytic Capacitors are bad, that might be the reason the Juno-2 is not turning on, OR getting power to the rest of the synth from the Power Supply board.
Any ideas would be greatly appreciated.
