Hi all, this is my first post regarding my Vizio Co-Star. I have had it since it first came out, and everything had been running smooth until about a week ago. I no longer get any signal to my TV from my Co-Star. I have shut it down and restarted it (unplugging and re-plugging the power). I have double checked all my HDMI cables and the cable box. Not sure what else to do. The power light is solid when it is plugged in. Has anyone come across this issue? Did my box die? Any help appreciated, thank you!
