I have had the Express+ for just about a month. It set up fine; I was able to add my channels and get logged into my Netflix, Disney+, etc. Now the light is not on and the TV says no signal. I have already tried changing the HDMI port, changing the HDMI cord, unplugging/plugging EVERYTHING back in, reset button, and no results. The light on the Roku is not on and I still get the "no signal" message on the TV. Any ideas on how to fix since I cannot call into customer support?
