Hi every one! I have an SK 20 Symphonic Ensemble which I love it, I am trying to fix all problems it is has right now, but one of them I don't know how. When I turn it on starts a constant noise like a hi frequency that sounds on every outputs. You can listen it on this link. https://www.youtube.com/watch?v=U4PIEiXCrNY
Does any one have an idea what could be the solution? I would appreciate any help!!
You should contact Yamaha Customer Support / Service Deparment - they can give you exact details. In the back of any Yamaha Owners Manuals are the contact info in your area. Or you can contact them via email via the SUPPORT area on the main Yamaha website.
Thanks, I will do it.
