Recently I have been experiencing an issue with the above mentioned Roku TV. The set is completely off & suddenly tries to turn itself on again, half the screen lights up then slowly fades away. As there have been issues in the past in my neighborhood regarding their of Wifi, I think someone has the MAC address of my TV & is trying to use it to hack my Wifi. My partner says it's a software issue with the TV itself... Any ideas? Thanks in advance.
