Q990D HDMI Ports Quit Working

[useru0G76TQYOm]

UPDATE: I have no sound even through the eArc port. Sound only comes from the TV

So I usually have my PC hooked up to HDMI port 1 on my Q990D and use eArc going to my S90D. This has been working fine for months until today. My PC no longer sees the soundbar.

I tried to plug the hdmi cable from my pc into the TV and I get a picture, but I can't get any sound out of the sound bar. If I turn on QSymphony I can hear parts of the audio from the TV but nothing from the sound bar. 

I did a factory reset on the sound bar and still had the same issue. Any ideas? 

My blueray player doesn't seem to get picked up by the sound bar either. I get no image when I go to external devices on my S90D and then to hdmi 2 on the sound bar.

Same happened with me, auto updated to 1024.1 and now facing this! Before this my soundbar was working perfectly. Tried resetting and everything but nothing work on eARC

updated accidentally from 1021 to 1024 and this happened to me as well, so upset

I have the same issue, except mine is a new soundbar. everything seemed to work for couple of days, and now no sound on the ARC connection. Updated version is v1024.1. So frustrating.

I have same issue. I can only power on and off. No connectivity. I can't even factory reset. Even deleted devise in smart things and when try to reinstall devise it cannot be found. It's useless.

Came here to investigate.

I’ve had the Q990D for like a month with zero problems and then all of a sudden today it will not play anything that is outputting Dolby Atmos.

Everything else seems to work, but nothing with Atmos.

Wondering if I was hosed by a recent firmware update…

I have the exact same problem after update 1024.1 which was performed without my consent at a samsung repair centre because I sent it in for repair concerning the subwoofer. 

So i received my 1000 euro soundbar with more issues than I had before!

After the forced update that bricked so many soundbars, and now this. Samsung, you're done. This is utterly ridiculous and totally unacceptable!

I have a Q990C but both of my soundbar’s HDMI in ports stopped working as well.  The arc still sends audio back to the soundbar thankfully but it will not send video single out from the soundbar.  It appears to not even recognize anymore that something is plugged in and sending signal to those ports.  Stopped working suddenly.  Worked fine with a Nintendo switch 2.  Turned off the game and when to boot a different game and it went out.  Hasn’t worked again.  Tried it with a Sony blu ray player and same result.  I once got it to flash the Sony logo when booting for 3 seconds and then it went out again.  I’m well past warranty at this point - not sure what to do.  Also on FW 1024.
