The motor doesn't work. i was told to unplug the power supply hold the power button replug the power supply and hold the power supply for 20 seconds and that didn't work. The motor makes a noise. The screws that came with the motorized arm didn't fit the holes in the frame. The frame wasn't bought with the motorized arm. I was able to use other screws. At this point I would like to return the item for a full refund.
