Re: Selecting a netflix channel loses HDMI signal

Thanks for the notes. We're currently investigating these reports, and appreciate the helpful details. 

In the meantime, try adjusting the output resolution in Settings>Display type from 'Auto' to one of the manual display type options to see if this helps resolve the issue. 

I'll continue to provide any additional updates once they are available. 

 

Thanks!

Re: Selecting a netflix channel loses HDMI signal

Model 4640X

Software version: 9.2.0 build 4131-29

For me it seems to be once per day.... I get netflix logo, then black screen and tv no longer able to detect signal (Vizio 65" 4k tv). mashing buttons does nothing but make the led on the roku flicker.  Unplugging and plugging it back in(power) will fix it for the rest of the evening, but I can pretty much guarantee that tomorrow when I get home and launch netflix it will do the same. I've uninstalled netflix channel, reinstalled.  I've done a factory reset on the roku. No improvement. One other thought I had was screensaver, so I've disabled it. (shot in the dark).

 

Re: Issue with Netflix on Roku - No picture and Crashing Behavior.

Mine started two days ago.  I have tried everything outlined in this thread and still having the problem.  I'm a software engineer by trade and this look like a software bug to me.

Re: Selecting a netflix channel loses HDMI signal

I am having the same problem but only when I try to go to Netflix.  Has it been solved?

Re: Selecting a netflix channel loses HDMI signal

OK I changed the display from from Auto to 4K 60 Hz (without HDR) and it's working.  It failed when I used the HDR setting.

Re: Selecting a netflix channel loses HDMI signal

Could you please tell me how to stop my Premiere+ from reverting back to Auto? Someone here posted a series of button pushes on the remote, and I have never gotten it to work.

Re: Selecting a netflix channel loses HDMI signal

I've been told that they are trying to figure out what is causing the problem, but after they fix it, they are going to have to push another software update to all of the Roku boxes.
