Solving playback issues

[konombut]

I have a Roku express I use on my Vizio TV. While streaming the screen will go black and show no signal then go back to streaming. For most streaming services it will go back to the stream but if it is a live show it’ll go back to the menu of the platform.

Example: if I’m streaming on the CBS app watching a show live it’ll show the no signal then go back to the CBS menu

This is the second Roku express I’ve used on this Tv and both have had this problem. Is there a way to fix this issue or is it just the TV. When I used the first Roku on a different tv it worked perfectly fine.

There’s not an issue with the wifi or anything. Is there anything I can do to fix this?

If you're using the TV's USB port to power the Express, try a USB power adapter/charger from a phone or tablet that can supply at least 1 Amp.  Some TVs' USB ports can't supply enough power.
