I have a roku rk sound bar and on the home screen from start up its fine but as soon as I try and streme a video from Netflix sling exc the screen starts glitching on and off. It goes on for a second and off the next saying no signal and goes back and forth. I have tried restarting the device, changing hdmi ports on the TV, and changing hdmi cables. Any help is appreciated, I payed $140 for this and have not been able to use it once.
