Intermittently, while watching any channel, the screen will begin a right to left rapid scroll. Nothing will stop the scroll. It appears to eventually reset, but not because of anything I've done. When it resets itself, it goes to the ROKU bouncing screen.
We'd like to know more about how we can help. How are you powering your Roku device? Is the device plugged into the TV USB port or is it plugged into a wall outlet? Have you already tried performing a factory reset on the device to see if you can get past the bouncing Roku logo screen?
As a last resort, if you are still experiencing an issue, we would recommend disconnecting your wireless network, then rebooting your Roku device to see if your Roku device is experiencing the same issue. Once the device is getting past the bouncing logo screen, try reconnecting your wireless network.
Keep us posted and we'll continue assisting from there if needed.
