Hi, just bought a roku express and tried setting it up. When I turned my tv on and plugged the roku in, the roku would blink a couple times and turn off without ever displaying anything on my tv. I tried switching the HDMI cable to a different one and the same thing happened, I also tried a different port on my tv as well. Any help would be appreciated.
I tried for about 20-30 minutes to get it to stay on. I’ve unplugged it and retried many times, it’ll turn my screen black for a second after plugging it back in and then back to no signal and the roku will stop blinking and turn off.
