PS5/Chromecast Ultra Screen Flash

[userGKtBs7bnEA]

On my un58mu6071 I have a PS5, Chromecast Ultra, and a Firestick 4k (connected to a Samsung soundbar). 

Enabling Anynet+ and HDMI UHD Color causes the TV to flash a black screen on the ports where the PS5 and Chromecast are connected (tested all ports). The Firestick drops audio randomly.

Disabling Anynet+ allows for HDMI UHD Color to be enable without issue but the soundbar no longer play audio. Also, all devices must be turn on individually. No issue with audio from the Firestick. 

Disabling HDMI UHD Color allows for Anynet+ to be enabled but the PS5 is picture is very dark which means messing with contrast and brightness every time you changes sources. No audio issue from the Firestick.

Is anyone seeing this issue?

Are you running everything to the sound bar and then the television or to the television and then to the sound bar?

Please go to Settings>Support and provide the current software version of the television.

[userGKtBs7bnEA]

The Chromecast and Playstation are both connected to the TV itself. The Firestick is connected to the soundbar.

Software version is T-KTMAKUC-1280.5.

Have you tried connecting everything to the television and then only using the soundbar for ARC? 

Have you tried a factory reset?

[userGKtBs7bnEA]

The TV only has three HDMI so one device will need to be connected via the soundbar. But I did try disconnecting everything but the Playstation and I still had the same issue. I tested the Playstation on all three ports.

Just tried doing the reset but the issue remains.

Do your HDMI cables support 4K HDR? Is the software on the soundbar up to date?

[userGKtBs7bnEA]

Yes, the Playstation is connected using the HDMI cable that it came with which is HDMI 2.1 and it does support 4k HDR. I've tested the PS5 and cable on my 4k monitor and I'm getting 4K 120hz with HDR without issues.

I just upgraded the sound bar (HW-T510) to 1004.0 and it didn't change anything.

The next step would be to set up the unit for service. When was it purchased?

[userGKtBs7bnEA]

It was purchased 11/10/17.
