Hello, I hope you're doing well. I bought a Samsung sound bar HW-Q600B in April 2023. Everything was okay until I moved to a new place, and when I tried to turn on my sound bar, it said "CONNECT USB" and nothing was working. I cannot change it with the remote because it's not working. I tried to change the source by the button on the sound bar itself, but it stuck on the "CONNECT USB" option. The power button is not working and if I press the source button on the device, it says "BYE" and nothing. I tried to install the firmware update via a flash USB stick, but it showed me "UPDATE" and after a few seconds, the screen turned black, and nothing. I unplugged it for a while and plugged the power cable again, but no progress. I cannot reset the device either by pressing the + and - buttons.
