Our Insignia Roku 5302X TV has worked great for years, however recently we have started having a problem with it. What happens is that it randomly turns itself on and it will not turn off with the sleep timer. It has the latest software version on it and I just double checked that. We are not sure what is causing these new issues as it has just only recently started happening and there have been no other problems. Just wondering if there is something we can do to fix it as we do not want to have to leave it unplugged until we want to use it.
