randomly it is disconnecting my q90r soundbar. I have it connected via arc it changes from TV ARC to DJN. The sound bar firmware is up to date. Is there a way to go back to the previous firmware on my TV before this issue started happening.

I'm having the same issue with my Yamaha YSP1600 soundbar. I've already had the main board replaced on my Q70R and after the firmware updated the issue returned within 24 hours. New mainboard getting swapped in today. Soundbar has been running without issue on another tv for a week so it is the TV and, most likely, the firmware. Will see if the engineer has any knowledge of the issue from elsewhere.
Oh, and Samsung don't allow downgrading. Only way to go down is to replace the mainboard.
