Do it the other way around. You turn on the tv with tv remote and let CEC turn on the Bose. When finished watching, use tv remote to turn off tv and let CEC turn off Bose.
Thanks for the posts!
Are you able to change the CEC mode for the Soundbar 700 in the Bose Music app? You can change CEC Mode to "Alternate", which may help.
Are you able to use the Bose remote instead of the Philipps? This may help reduce issues.
