TV Remote control volume button stopped working

[userHr1MO17Zqo]

I have a Samsung QLED TV, model QN85Q70AAFXZA. I've had it for a few years and everything's worked fine. Now, with no other changes, the volume button has stopped working on the remote; I can neither raise nor lower the volume, which I unfortunately set to 10 this morning, so it's lower than I'd prefer if it has to be stuck at something. All other buttons and functions work exactly as normal. There's no feeling of damage to the button, and it doesn't matter if I hold the raise or lower volume button for a while, or if I press more firmly. The TV has all the latest updates, and the self diagnosis says the tv is fine. The remote control is fully charged. The remote control is the one that came with the TV, and the remote control model number appears to be RMCSPA1EP1 - it's the solar-powered version. The sound output still works, and it's the standard TV speaker. Any thoughts?

If you have a Samsung Phone through smartthings app you can use the remote there to see if volume can be controlled. If so you'll need a new remote. In the US they're available on Amazon.

Hello, userHr1MO17Zqo. Welcome to the Samsung Community! Have you attempted a factory reset on your remote?

To do this simply, press and hold the Return and Enter (center of the navigation pad) buttons for more than 10 seconds.

After the reset, you'll need to pair the remote with the TV again. To do this, Point the remote at the TV's IR sensor. Then, Press and hold the Return and Play/Pause buttons simultaneously for at least 5 seconds, or until a message appears on the TV indicating that the remote is connected. Please, let us know if this helps!
