when my mother uses the roku occasionally the sound goes out but more often the picture blows up so she only sees a small fraction of the picture on the whole tv. she unplug and plug the roku back in and its fine for a while but it still does it randomly!?!?!
Can you please clarify the issue you are experiencing? Does this issue happen on a specific channel or does it happen on all channels? Doe this issue occur during specific times - during/after a commercial, during playback, on the Home screen, etc)?
With more information we will be able to assist you further.
I am having the same issue with Roku Zooming in picture even at start up, before opening any app. I purchased the Roku Express+ in May 2020 It started happening on occasion a couple of months ago. Last night I had to unplug/restart Roku 3 times within 2 hours. The Roku box is also getting extremely hot.
