Software version: 9.4.0 Build: 4183 scrambled most channels

Just updated my 2019 Roku Ultra to Software version: 9.4.0 Build: 4183 this morning because some channels would not come up. They would just spin for a few seconds and take me back to the home screen.

I uninstalled and reinstalled the channel without success.

I then checked for and update and installed it.

Now only a few channels will launch clearly.

Most channels will only show scrambled pictures.

Any help or ideas?

I would unplug the power from both the Roku and the TV for a few minutes and then plug them back in.  I've seen TVs lose their marbles before.

Thanks for the post.

When removing a channel, please make sure that you restart your Roku device before adding the channel back again, specifically in that order.

Please keep us posted what you find out.
