Roku and App UIs display but only black screen for content

I have tried both a Roku Ultra LT and an Express 4K+ with a Panasonic Plasma Screen TV.  Both the Roku UI and various apps (Amazon Prime, Netflix, YourubeTV) interfaces display correctly but once content is selected I get a black screen. I used both auto detect and selecting lesser resolutions for the display type with no improvement. We have a very solid internet connect. I have also tried 3 different HDMI cables.

Any suggestions?

Re: Roku and App UIs display but only black screen for content

My device express 4k+ upgraded to 10.5 also has the same problem. This problem can only be solved by restoring the factory. After restoring the factory, the problem still occurs after restarting the device.

Each restart must automatically restart twice to enter the system

ROKU OS 10.5

Model: 3941X - Roku Express 4K+

Serial number: X01600C4LMKC

Software Version: 10.5.0 build 4187 CR

Device ID S07P5154LMKC

Re: Roku and App UIs display but only black screen for content

I am having the same issue with my Roku and Sony TV. The menu and app UIs display correctly, but sound and video content do not work. The progress bar show that the content is playing, and the preview thumbnail shows up when skipping ahead. 

Sony Bravia 1080p TV w/HDMI 1.4

Roku Express 4K+

Model 3941X

Software V. 10.5.0 build 4187-CR

I have tried adjusting the output settings from 1080p to 720p and back again, with no change. 

Any ideas?

I solved the issue by factory resetting and going through the setup process again. I just received the Roku today, so strange that the first setup didn't work. Oh well.

No video from any channel

Got a new roku express 4k. Set everything up and all looks good until I try to play a video then all I get is blank screen and no sound. I have progress bar and can see the the picture as I move across it but play from anywhere and nothing. Have tried multiple channels and same result. Tried 720, 1080 and 4k. No difference.

Re: No video from any channel

@Arod3367, have you tried swapping devices (keeping all cables in place) to see if the problem stays with the device or the TV?

@Jut_72, have you tried different HDMI inputs and/or different HDMI cables?  Can you try another TV?

Re: Roku and App UIs display but only black screen for content

I tested it a few times yesterday, and I suspect it has something to do with the theme. It seems to be fine to use the default theme.
However, it still appears that it needs to be restarted several times after the machine is turned on before it can be used normally.

Black screen on new device

I bought a brand new Roku Express after a previous one stopped working and I thought it was my device. It connected and goes through all steps fine but when I try to play anything (hbo Max, Disney+, etc) the movie / show will not play. It stays black with no sound. If I rewind or fwd I can see the pictures but it won’t actually play any content. Any advice? Thank you !!!
