Streambar is auto-dimming to low brightness

I received my Streambar from Amazon yesterday. Everything works fine (sound is really good) but when I switch to Roku input (using HDMI port 3 ARC), it will auto-dim to a low brightness setting making it impossible to watch movies. It happens when using any app/channel and sometimes when just browsing to Live TV. I have used just about every other streaming device and have never experienced this before.

I have a Samsung 6 series 55" UHDTV MU6300. I've tried all of the display settings and none fix the issue. I've tried different HDMI ports, cables but no success. I contacted Roku tech support and they just told me to restart/reset which is very frustrating. They blamed everything other than Streambar. This must be a display setting that I can't access in the UI.

is there a technician menu for advanced settings?

Thanks,

Todd

When switching inputs to Streambar the screen starts out properly bright and then dims when I launch an app like Netflix or Youtube. When I switch input back to another device the screen returns to normal brightness.

I used the cable provided in Streambar box. Also, it only dims when I enter app/channel so it's not the cable.
(10:45:14) Todd Thompson
My email is todd.thompson.mail@gmail.com
(10:46:35) Rajarajan R
Yes I have send please refresh or please check in the Junk file.

Okay Thompson to fix this issue can we perform the Factory reset?
(10:52:50) Todd Thompson
I've done that once already
(10:53:13) Todd Thompson
I'd have to re-add all of my channels and credentials
(10:53:41) Todd Thompson
Is there no way to adjust video settings in Streambar?
(10:54:57) Todd Thompson
You are not helping me
(10:56:20) Todd Thompson
I just to to stop the auto-dimming. This must be a setting somewhere
(10:56:32) Rajarajan R
Thompson I am sorry for the delay I am checking with my team.
(10:59:00) Rajarajan R
Thompson could you please check with the another Tv ?
(11:00:28) Todd Thompson
It's not the TV. I've had this TV for years and used just about every streaming device Google, Fire TV, Directv, Xbox, etc. This is the first time this has happened.
(11:01:07) Todd Thompson
Why would I bother going through this with you if it was the TV
(11:01:36) Rajarajan R
I understand we need to check with alternate TV and if that works we can use again with the older one since this is also a Troubleshooting.
(11:01:58) Todd Thompson
I dont have another TV available to test
(11:02:38) Todd Thompson
It is a Samsung 6 series 55"

(11:03:50) Rajarajan R
Please perform this steps for the last ti,me.
1) Disconnect the Roku device from the TV and the power cable from the Roku device. Wait for 30 seconds, and then connect the power cable back to the Roku device and connect the same to the TV.
2) Once you see the bouncing Roku screen loading on the TV, push and hold the reset button that is on the device for 20 seconds.
(11:04:19) Todd Thompson
I've already done that
(11:04:51) Todd Thompson
It takes at least an hour to re-add all of my channels
(11:05:41) Todd Thompson
Please understand. I just got this Streambar yesterday
(11:06:13) Rajarajan R
I understand Please perform the steps again for the last time please.
(11:06:21) Todd Thompson
I followed all of the instructions for setup
(11:06:29) Rajarajan R
I understand Could you please give me 2 minutes while I check this information and get back to you?
(11:06:37) Todd Thompson
Im not going to factory reset again
(11:08:04) Todd Thompson
This is a software issue with the Streambar or a setting for auto-dimming that I cannot change
(11:09:31) Rajarajan R
As we perform the system update so I request you to change the HDMI cable
(11:10:07) Todd Thompson
So far you've blamed everything but the device.
(11:13:33) Rajarajan R
Thompson I request you to replace the HDMI cable and check if that fix your issue. I am sorry for that we need to identify the issue is with the stream bar or with the HDMI or with the software.
(11:15:08) Todd Thompson
I changed the cable and the HDMI port. Exact same issue
(11:18:51) Rajarajan R
I am sorry for that Could you please check have you received Email ?
(11:20:14) Todd Thompson
No email
(11:24:37) Rajarajan R

However, the issue that you're facing is a peculiar one which has to be investigated by the backend team. In order for me to forward this, I would need the following information from you.

1. Issue ID (please push the home button for 5 times and then push the back arrow button for 5 times which is right next to the home button).
2. Your software version, build version and software update last checked date and time (please navigate to Home> Settings > System > System update) and your time zone.
