I have a problem with micromaster 420. When I conected, I cant see anything on display. Also, coupling noise cant be heard in micromaster. Micromaster is properly fead. What can be? Thank you.
sounds like its toast to me, if its a small drive, toss it, buy a new one, a larger drive might bw economical to repair. Anything over 20kw I send for a quote to repair, then decide
