I have a Roku branded TV, it has the Roku logo in the middle at the bottom, so it is Roku branded and not another manufacturer. I have had the Roku TV since early April. I have had several problems, such as incessantly disconnecting from WiFi, I solved that problem by simply using a hard wired network connection. My current problem: when I power on the TV it comes to the Home screen and then within a second, it automatically goes to "powering off" and it powers itself off. I have to press the power-on button again. So far, it will power-on, but it shouldn't power itself off immediately after I power it on. How can this be fixed?
