While trying to adjust my sounds the screen on my FVB shortboard and on the amp went blank although still lit. All the front panel lights ie-A.B.C.D.are off and no sound. I have tried turning off and on, also pressed A while turning on which is suppose to put it to factory settings But nothing works.unpluged shortboard still not working anyone had this problem or how to fix it?.
