My personal unit that I used and works great! *The IEC power is working but can restart if the unit is tapped by the AC power connection area.  But if left alone, works as should. But can flicker so maybe a lose solder or grounding issue. BUT...

I am including my workaround for the IEC and bought a 12V to AC 4 pin XLR power supply and it works 100% into the 4PIN XLR which is totally solid.  I prefer this as the XLR is a locking connector unlike the IEC.  

*Monitor shown in pics NOT INCLUDED.  Photos are of this unit in a professional working environment.

Please reach out with any questions.
