What should happen when I first turn the 5vdc power on to my 595. Are any of the LED lights suppose to come on other than the red power one? Because right now i'm having problems with mine. I turn the power on and sometimes no LED come on times anywhere from 1-5 come on and sometimes they all come on. Also doing the channel test from within Vixen the all on and off will work a few times then stop. Any ideas?
