My Roku Express 3930X that I've had for years did the same thing. Screen froze when I was watching. I unplugged and replugged everything and did a hard reset (held reset button down on back for more than 30 sec). I figured it died of old age so I got a new Roku Express 3960RW today. It came with the streaming device, a remote, some batteries, the HDMI cable and a USB cable. No wall plug. My old unit didn't have a wall plug either. I disconnected the old unit and plugged in the new unit exactly the same - one end of the HDMI cable to the back of the Roku, the other end to the back of the TV; one end of the USB cable to the back of the Roku, the other end to the back of the TV. I'm getting nothing on the screen. I made sure I was on the correct input location, unplugged and replugged everything, did a hard reset. Nothing. And the light is flashing on the front of the Roku. What is causing this? I have a Vizio TV. The TV is powering on and I can manually move thru the menu for the input locations, so I know it's not the TV. How can I get this thing to work???
Building on RokuNimfa-C explanation of insufficient power supply of your TV USB power port (sometimes they wear out), try using a wall adapter plug at the wall outlet and see if that resolves your issue.
Try using a cell phone USB charging wall adapter (5volts, 1amp) since your device did not come with one.
Unplug the USB power cable from your TV, plug the USB into the power adapter, and plug power adapter into wall outlet.
If it resolves issue, try the wall power adapter with your old Roku device as well.
I am have the same issue! Starts to boot up then in a few seconds the blue light starts flashing and it shuts off! 😤 I have changed the power cord, plugged it into the wall and tv -everything! Continues to do it!
