X1 box not working
I have had the box just sitting around for a few months, just now setting it up for my father. However, when I connect the box, it will only display the Welcome screen and then say No Signal. I have tried swapping all of the cords between the TV and the box but the issue persists. I tried the box on another TV and all was fine, but when I tried another box on the first TV(The box that was working fine before) and the same issue came up.
the box will also display codes like boot, 1PSt, S1St. Anyone know how to help?
