I guess what he means is that he tried them on the machine, but because they showed nothing he's not sure if it's the monitor(s) or the computer. No beep means something is amiss. It might not even be getting as far as the POST routine. If this is the case nothing would show on the monitor.
Stll, these 5051s are fairly straightward machines with off-the-shelf (for the early 80s) components. Problems tend to be fixable.
