When I got this monitor at first it had one dead blacklight inverter but it did work. I put it into storage for six months and now when I try to use it (prior to me spending the afternoon opening it to replace the inverter coil) the thing is dead to the world. The power button is useless and when the G5 is powered on from its power button the monitor displays nothing and the power lamp for the display does not even light. no power over USB either. It's like it's not even plugged in....even though it is.
