QN85QN900AFXZA 1. Turns itself Off Browsing Internet & 2. Keeps Switching TV Speakers from AVR

[userMXB7XweU8V]

Hello,

I've had the 85" QN900A since 3/31 and have a couple of repeating problems.

1.  The TV turns itself off when I am using the Internet App.  I've also been able to repeat the turning off problem when using the Youtube app and pausing it.  

2.  TV will start up with sound coming from my Onkyo TX-RZ920 and 5.2.4 speakers and within a few seconds switch to TV speakers.  If I go into the sound menu, I can change Sound Output to Receiver(HDMI) and within a few second it will revert back to TV Speaker.  

As a workaround I go into Expert Settings and turn HDMI-eARC Mode from Auto to Off.   With this setting the TV will hold "Receiver(HDMI)" sound output.  After the TV warms up for ~ an hour, I can turn HDMI-eARC Mode back to Auto and the TV hold Sound Output "Receiver(HDMI-eARC)" for the most part.  

If I want to watch an Atmos movie in Netflix it comes up as Dolby D+ until I go back and toggle the TV or AVR to get the AVR to display and play "Dolby Atmos".  I haven't nailed down what exactly fixes that issue since turning off the TV also turns off the AVR and turning off the AVR also turns off the TV.

Feel free to contact me if you have any questions.  

If you aren't already, you might want to monitor the QN900A owners thread on AVS Forum  for other owner issues.

Thank you,

Mike

How long does it take before TV turns off while using the Internet app? What about YouTube app while in its paused state?

[userMXB7XweU8V]

Anywhere from 10 minutes to an hour once I've opened the we browser.  

I tested YouTube just to see if it would happen in another app.  I paused YouTube and the TV shutdown in about 20 minutes.  

I'm thinking it may be occurring after an app is opened and there is a period of inactivity.
