HDMI CEC issue with samsung tv

Hi all,
I have an intermittent issue with my x96 air running CE 20.4
The HDMI CEC funtions work just fine… until i power off coreelec from the menu.
The samsung tv which is connected via HDMi1 will power down, then about 5 seconds later it powers back on again.
This doesnt happen all the time but id say 50% of the time.
Any suggestions?
