Roku setup

[Staci3]

I’ve been using my express Roku for about a month, now the tv says mode not supported and the Roku box has a white flashing light 

I’ve tried resetting the box, changing the batteries, switching the HDMI outlet, changing the plug in, changing the HDMI cord. 

any suggestions

Thanks for the post.

Can you please specify the issue you are experiencing? What are the steps to reproduce the issue? How are you powering the Roku device? What make and model TV are you connecting the device to?

For troubleshooting purposes, have you tried connecting the device to another TV to see if you are seeing the same issue occur?

Please keep us posted what you find out.

Thanks,
Danny
