I have a Philips 50pfl5604. I promise I have tried to answer this online, but I don't know where else to turn. Philips is closed until tomorrow. My TV has chromecast built-in. I need it off because it is interfering with the TV in the other room. We have never used it but when we try certain apps on the other TV we get a pop-up wanting us to connect to it. (Example is Paramount +, Vudu, and Crackle) we can't close the pop-up on the other TV. All I can figure is I need to shut it off on my TV so it isn't showing on the network. I'm sorry if I am being dense. I really appreciate any help. 🤗
