New to the board, so any post or advice will help.
I was using the LEDrain 38 one night before a show, I ran programs on it and worked perfectly. I left them overnight and came back the day of the show and when I went to turn them on, all of them did but one. I checked the power source and cords, dipswitches and fuse but to no prevail. When I turn it on also it makes a sort of buzzing sound, not loud but can hear it. Don't know if this is a simple fix or not. Any help would be appreciated. Thanks.
