I have a 2020 The Frame 65". I use an external amplifier (NAD AMP-1) which volume is controlled from the smart remote via the Infrared out on the One Connect box.
Everything works great when I adjust the volume one click at the time. But if I press volume up on the smart for a few seconds the volumes increases indefinitely. I have to turn off the TV to stop the volume from increasing.
I can see that it the IR out on the One Connect box that never stops to flash. What can I do?
