It's hard to find a good subreddit to ask this on, but since my TV is an Android TV and this subreddit is active, I'll give it a go.
I have a Philips 49PUS6432/12 Android TV and recently got a CI+ Module for it so I don't have to use the old STB. It's working fine but for some reason almost every time I start the TV I get the pop-up message "Common Interface Successfull" and have to OK it every single time.
Is there a way to turn this off?
I'm not familiar with your model. Is there a power saving setting, on anything setting that might control how the TV turns off. Energy saver, quick start, etc.
Maybe switching to a mode that puts the TV to sleep instead of fully turning off would keep your CI+ module powered/initialized...just a guess, good luck!
