Hey, I have a Viewsat Ultra and when I put the fixes on via USB from time to time my receiver will freeze on the Do not power off screen. So when I power it off it comes up with "----" on the display. I found the instructions on how to fix this and have done this many times by loading the program via null cable and everything is fine. This last time I loaded the program to bring the box back to life everything looked fine. When I plugged it back in at my TV though, nothing came up on the screen...nothing. I know it is still getting power, but I have no idea if it can be fixed. It must be fixable but any help on this would be much appreciated. Thanks again.
