Brand new Q990H soundbar, yesterday and this morning when turning on I'm getting sound from the soundbar but nothing from subwoofer or rear speakers even though they have solid blue lights on the back of them, I'm having to unplug them and the soundbar from mains and plug back in to get them to work. Is there a fix for this? Thanks.

it can be a lot of things but I think it is from the device. Did you left the device plugged in while it thundered, and did you left the device on the mains at that time? By the way, is there Grounding done on the outlets?

Hi I’m having the same issue on the latest firmware. Was there a resolution? I have to completely power the main unit to fix it

What was the part? Did they conclude there was a problem?

The part was the mainboard. Apparently that is the issue.

Thanks. Yeah that’s not great. This is a really frustrating issue. I’ll need to take mine in sometime this week. Awful support for a brand new device

I've just seen on a Facebook group people saying they've had to have the mainboard changed in their Q990F soundbars. You'd have though this issue would have been rectified before releasing a new product.

Samsung have been really good, they sent engineer out who basically said pointless getting ut repaired. He sent report to samsung, samsung have arranged dpd to collect it tomorrow, so should have new one in a few days.

That’s a great outcome for you. I’m glad you’re getting a new one. I’m in Australia and my experience hasn’t been as positive

So an update. I rang the retailer that I bought the soundbar through and explained the situation. They were very accomodating and said to bring it down and they would exchange right away. They were great. I’ve now set up the new one and it’s not showing the same issue! earc is now turning on main unit and the rears are working!! I have not updated the firmware and won’t as I’m not sure whether it was a hardware issue in the first unit or a software issue with the latest firmware. So I’m not going to connect it to my home network. Hopefully it’s all now resolved.

Hi, I've had the same soundbar as you since Monday, and I'm having exactly the same problem. I installed the latest firmware right away, and I can't tell if it's a software or hardware issue. Either way, I'm really frustrated :

So you only bought the soundbar Monday and then installed the firmware and having the issue? That exactly replicates my scenario. I had tried to reset the soundbar to its factory settings, but it didn’t take the firmware back (or maybe it reinstalled the firmware when I connected to check). So far the new one has been working and I haven’t installed the latest firmware. Personally I suspect this is software rather than hardware (because switching on the soundbar first doesn’t produce the issue), but that’s just a guess. It really needs someone from Samsung to comment. Which being a premium top of the line soundbar wouldn’t be unreasonable.

Yes, that's exactly it. I also think it's probably a software issue, though I'm not entirely sure... It would definitely be nice if Samsung provided an explanation and a solution, especially if it is a software issue.

Annoyingly auto update is set as on by default if you add the soundbar to smarthings. Wondering if it can be turned off quick enough before the app updates the firmware
