HDMI-CEC Not working correctly



I was just wondering if you could assist with this? I’ve installed the CEC control app on the devices (DSCS9) and sent the command, but it flashes off then comes back on straight away.

Any ideas as to why this would be happening? I copied the commands directly from the guide on how to set it up.



Disable one key power on the box. Leave one key power on tv ON , and one key power on box to OFF
