Sorry to see you've had trouble with your remote volume button not responding after you changed batteries.
Could you advise if you get an error message or code displaying on your TV screen after this problem came up and batteries were replaced?
Also please, try the below fixes:
1.Press power button on the TV box for 10 seconds
2.Press TV + 0 buttons on the remote for 10 seconds
You should a see message on screen stating that the pairing was successful.
If the above does not work, please try this:
go into the Settings>Audio & Video>Pair Remote With Device then select the option for Change TV Setup from there you can manually choose your TV manufacturer and setup the remote control to pair with the TV
In case this is not of help either, you can reboot your TV box by turning it off from the on/off switch at the rear left-hand side of it for 10 seconds, then turn it back on and see if the issue has cleared out.
Let us know if any of this works for you. Please, feel free to ask in case you need more assistance.
