After initially setting up the Roku device on the Google TCL TV using its own dedicated HDMI port for the streaming stick, I am experiencing continuous issues where the device just drops out from the HDMI connection after shutting the TV down. I continually have to re-setup the remote then re-establish the account for the stick and allow it to update all the apps as if it were setting up the account for the first time. It has gotten to the point where it is dropping me out of a program I am streaming. The internet connection is excellent. I run two other streaming sticks on the same network on different TVs with no issues whatsoever.
After turning on my TV after a successful shut down from Roku, I toggle my TV input to the streaming stick HDMI and I get the screen to set up the remote. This happens about 75% of the time. Is it a faulty remote? A faulty stick? I've checked and re-checked my stick connections.
What is going on?
By any chance do you have the USB port plugged into the TV? That can cause mayhem if the TV doesn't supply quite enough power.
If you are saying the Stick is performing a factory reset every time you power it off, I would vote for a defective Stick. I carry a Stick in my suitcase that might not be powered up for weeks or even months, and it's never done that. I have another player (Premiere 3920) that I power from the TV's USB port so it's powered off whenever the TV is off, and it too has never done that.
But re-reading your post it seems it's just the remote that needs to be re-paired? I've never encountered that either, but it does seem to point to either the player or the remote. No real way to tell for certain from a user's point of view. You could use the Roku app on a phone to control the Roku after you turn the TV on, then go to the Settings/Remote menu and see if it still shows paired there. If it does, my finger would point at the remote being the failed device. If no paired remote is listed, then we're back to either one, although I would be more suspicious of the player in that case.
