@Laura64 Thanks for the note here. Is anyone is your house using the Roku mobile app on a phone or mobile device connected to the same network as your TV? They would be able to use the remote functionality built in to perform all the functions you described.
You can try disabling control by mobile apps in Settings>System>Advanced system settings>Control by mobile apps to see if this helps.
If you need more help from there, feel free to contact your Roku TV manufacturer for additional support. You can locate their contact information here: https://community.roku.com/t5/Manufacturer-Support-Warranty-Resources/Contacting-Support-for-Your-Ro...
