We just installed a Samsung TV model QN65Q70T. Every function of the remote works except the volume button. When pressing the volume button, mute appears; however, we are unable to adjust the volume up or down. We have tried turning off the TV, taking the remote batteries out and holding the power button for 50 seconds, but this did not work. The volume will increase now, but NOT decrease. Also, I managed to turn on a "little voice" which tells me everything happening. VERY ANNOYING! I can not determine how to turn it off. When I press the microphone, a screen appears to "sign into amazon." Shouldn't I be able to tell the TV to turn the sound up or down? PLEASE HELP.
There's a quick check to perform to figure out if it's your remote or your TV at fault. Remote is flashing but not responding.
Reset the remote
Check to see if the remote is sending an IR signal.
If you have a Smart Remote, try to pair it with the TV.
Press and hold Return and Play/Pause simultaneously for at least 3 seconds until a message appears on your TV indicating that the remote is now connected.
If the remote will not pair, get your phone out again (or another similar Bluetooth device) and navigate to its Bluetooth menu. (On many phones you can swipe down to open the navigation bar, then touch and hold the Bluetooth icon to open its menu.) Look for your TV on the list of available devices.
