Started using converter box back in February. Everything was okay, got channels I was supposed to. Then May came and I lost ABC, and all of the PBS stations. Now since the DTV switch has happened, I got PBS stations back, but no ABC and no Christian stations. I just don't understand what happened. I mean, at the beginning there was no problem. Then as time goes on, WOW!! All kinds of problems. Can someone out there maybe figure out how to fix the problem?
