I have a Roku express purchased in May 2020. It has worked perfectly on the same TV, on HDMI3, never moved, just occasionally unplugged the power, until several days ago. When I turn it on there’s nothing, not even the bouncing letters. Just a black screen and no sound. The light on the device flashes when I press the buttons on the remote, but no sound or picture. Ive tried all the suggestions here and elsewhere online, unplugging for periods of time, resetting, using different inputs and nothing is working. I tried it on another tv and I still get nothing. TV works with DVD player and antenna. Any ideas or did I buy a lemon?
I did reset my Roku. When it came back on the blue light is flashing when I hit any button on the remote, but nothing on the screen. RE: Antenna. I only used it to make sure that the TV was working fine. I will call my service provider on Thursday.
First, turn off your router, turn it back on, then when everything comes back to normal in like before 5 minutes, on the back of the tablo, hit that blue button, also on the roku hit factory reset and undo the tablo channel . wait a moment and re do the tablo channel.
