OK everyone. I have looked through the related threads and I believe my problem is different. In the other threads, the users can still get the menus, etc to work. In my instance I get nothing, no video at all, until I restart the unit, which is no fun as the unit takes an absurd amount of time to restart. It has been working just fine for about 3 years, but now suddenly it seems to be blanked out anytime we go to use it. Any thoughts? It is a non-modded unit and our signal is via comcast cable card.
