My 117volt va-76 (has a sticker on it "117v 60hz") was overseas for awhile where 220v is a standard. One crew was using it wit 220v to 120v power converter. Than the other crew was using it and they either accidentally or due to lack of knowledge plugged it in into 220v directly and told me it was working. About a year later another (3rd) crew needed to use it, they plugged it in into 220 to 120 converter and the keyboard doesn't power up.
As I'm at the other side of the ocean it's hard for me to predict what happens or what is happening.
in order to troubleshoot this or investigate what happened I want to know first if Roland VA76's psu is universal? or just fixed voltage?
