Recently updated system as prompted. Now, I can access apps such as Netflix and Prime, view menus and all that, but when I go to play a piece of content, only audio plays and no video. This happened immediately after my Roku update.
Could you try to disconnect then reconnect all cables including the power cable? If still no dice, try using a different HMDI cable or use a different HDMI port and see if that resolves the issue.
Please provide us the following information if the issue persists:
-Roku device model
(these can all be found in Settings > System > About)
-Does this issue occur on a specific channel? If so, what channel and what version/build is the channel (this can be found by selecting the channel on the Home screen and pressing the * button)
-Tracker ID when this issue occurs (when you see this issue occur, press the Home button 5 times, followed by the Back button 5 times)
-Steps to reproduce the issue you are seeing
With more information, we will be able to assist you further.
I'm also having the same problem after my roku updated last night. I also tried disconnecting and reconnecting both the power cable and the HDMI cable. I tried using different cables, and HDMI ports in my tv. It happens on every channel/app I use.
I am having this issues after the update to 11.0.0 as well on my 4801rw. What works for me is to watch something on YouTube and then everything else seems to work normally. I believe it may have something to do with the refresh rate. It will be good until the device is reset then you will need to watch a youtube video again. This is what works for me
