Hello Ron,
if you see two files in firmware upgrade mode (jumper set) the QMX starts for the first steps. Firmware 1_00_027 is loaded already.
When jumper is removed the QMX should start when pressing the volume encoder. But if you see nothing at the display and no backlight maybe the start procedure isn't completed. Please tell us for normal start the supply current when volume encoder is depressed and for a few seconds after released. And which voltage do you use?
?
