I have spent so much time, trying to get this worked out. There is no help or proper videos. A person is non-existent. I moved my Tv from one side of my room to the other. I carefully disconnected all attachments. Including roku streaming stick. when replaced, only the streaming stick was having issues. iI followed all videos Ii could find. Cut power, changed batteries, reset button on device.. Nothing. he ROKU The screen shows the Roku logo, then after a few seconds blanks out. Then comes on again. The blanks out. Remote has no control on settings and they do not even appear. I reset my internet and all other products work, but roku remains off line. I tried to get into settings on my computer. cannot even find them. The videos only say to go to settings, when quiz about how. no such vided appears. I have three roku devices, the other two are working, but I have not moved them. Truly poor customer service to sell and disappear.
