To be clear, on a working unit, should the standby lights light up when turned on?
As soon as you press the button on the amp all the lights turn on blue, as you turn the zones on the corresponding blue light turns white.
I wouldn't play with the 110/220 switch especially if you have 220. Are you I the US? Is this in any sort of UPS?
Have monoprice confirmed the sent back units were bad, or admitted that they are having any issues with production? Doesn't make any sense.
Did you try any first in a different outlet?
I would try the next one at the office first just incase
