Iโve got the same exact issue on my HW-Q990D soundbar. Firmware auto updated and it seems to have bricked it. No response even after powering down the soundbar for an hour. Canโt even reset it as there is no response and the screen doesnโt even light up! Horrendous only had it for 4 months or so.
Iโm experiencing the same issue with my HW-Q990D soundbar. It automatically updated through the SmartThings app yesterday and then suddenly stopped working. Now, I can only turn it on and off, none of the other buttons respond. In the SmartThings app, it appears offline, but I can still check the firmware version, which shows 1020.7. Iโve tried all the recommended solutions, including resetting the soundbar, but nothing worked. I also contacted Samsungโs chat support. We went through all the reset steps together, but the issue persisted. Theyโve escalated the case, and Iโm currently waiting for their response.
I am busy on more forums with this. Mine also broken but in Netherlands there is somebody who did the update on the exact day the firmware was on Samsung website. So before over air auto update. His system is still working. Seems to be the over air update is not fully going OK so now we have a broken soundbar.
If they find a way the downloadable firmware will be install over the original broken software via service port than it should be possibly solved...
