I have a streambar pro connected to a samsung tv with two roku surround speakers and the sub. for a couple months it was great. Then when i would power on the screen would start flashing on and off at power up. I would do a factory reset and it would be great for a few weeks. Now every time i turn on the tv the roku home screen flashes on and off a couple times then blank screen. I have to unplug and replug in the stream bar and let it power up to get it to work. i have to reconnect the speakers every time which doesnt always work to get them to reconnect.
