Roku express turning tv on and off

I got a new roku express yesterday and I plugged it in on one of my TVs and it turns off every 15 seconds and turns back on it has a little glitching line through the screen and my tv worked fine before I plugged it in I tried a different HDMI cord and even a different power box and it still isn’t working I then plugged it into the other tv and set it up and it worked perfectly fine idk what’s going on it’s brand new
