No output on channels 1-8. All other channels fine. The audio in/out board was totally recapped about a year ago but I did not test the machine after I got it back. All interior connection are fine but there is a row of status LED's on the mainboard labeled "XIL DeBug." The one in the middle (designated D21 or D22 - hard to tell) is red while all others are green. Anyone here know what this means?
