Neither one of my Roku premiers are working. No blinking lights. Nothing. I tried the pin hole to factory reset. That did not work. I have changed TVs and power outlets. Still does nothing. They are both unresponsive.
There should be a light of some sort (white)on the front.
If not they are not getting power. And you need to focus on the power. They dont need to be plugged into the HDMI or anything else.
Power adaptor & USB power cable is where the problem is.
Juggle the ends of these wires while plugged into a known working outlet.
You should get a light if but for a second.
