Voyager screen goes black after some minutes..

Hi all,

My Voyager screen goes black after some minutes. Sometimes accompanied by a sine sweep that goes downward. In any case everytime after power-up after some minutes the screen goes black and then the sine sweep. Sometimes the screen will then revert to all yellow with no letters showing and I cant play any sounds. I did re-install my OS . It is on 3.5.

best,

This is not a software error. So reinstalling the OS won’t help. Check the power supply, if you are into synth repairing. Or contact Moog or a synth repair professional.
