I just got a MXiii 4k Android TV box. It has both HDMI and AV output and I want to use the AV output. The box came with a "AV" cord - 3.5mm phone plug on one end to go to the MXiii and regular RCA plugs(white/red/yellow) on the other end to go to the TV. When I connect the box to a tv using the AV cord, I get no signal. I checked the cord for continuity and shorts but it tests okay. So do I need to do something on the box, within Android, to get the AV port to turn on or is the box defective? Has anyone else used the AV port on this box or other Android TV boxes? I tried asking the seller but they don't seem to understand what I want to do - they just say connect HDMI and it will work. ( Once I know it works I want to connect the AV port to a DVD recorder and record some of what I watch to give to friends.) I've tried asking various forums, the seller and searched the web but I'm not finding anything so any help would really be appreciated. Thanks.
