Advertisements For about 2 weeks I had the newly added FIOS HD channels (i.e. FX HD East, Disney HD, WGN HD, Hallmark HD, Fox Business HD etc.), but as of a couple of days ago I've lost them and don't know why. They're listed in the guide as "to be announced", but when I try to tune them in I get a black screen and no joy. When I did have them working, there was no guide info and I just assumed it would eventually update. I've done a restart and forced connection but all to no avail. The only thing I haven't done is a guide setup. That is my last resort, but I don't think it will help. If it helps, I live in MA and the other HD channels work fine. Any ideas?
