I recently bought a new 4K UHD Smart TV from Philips, this one .
Before this I already owned an AndroidTV box with a Sony Bravia FULL-HD TV and everything worked fine.
Since this new TV the AndroidTV's remote interferes with the Philips TV. When I press the volume down-button on the ATV box's remote, i get sent to the 'USB source' menu on the TV, and when i press on the OK-button on the ATV box's remote, i get sent to the 'TV guide' on my Philips TV.
I think there's some sort of infrared disturbance/conflict. I have no idea how to fix this. Any ideas?
This subreddit is for devices running the Android TV OS. It sound like you have a tv box running Android. If so you'll likely get better help elsewhere. My only piece of advice would be to disable HDMI-CEC on the tv to see if that helps.
