Quoted from pookycade:I have power to U6 and chip enable and output enable are OK.
Im assuming the chip enable you mention here (OC) reads low as a high here (BLANKING) would effect the entire board. I'm confused on "chip enable" are you referring to the clock signal on pin 11? If so, this should not be high or low, but a clock signal from the CPU (SOL4) to change the state of the Q outputs. The state only changes on leading edge of the high going clock signal. If this is missing its most likely connection related
