Anywhere between -7 and +3 seems to be just fine for most SD channels. If it's red, I'd call Comcast and tell them you're having signal problems and that you need a tech to come out. They should be able to repair it.
I get "analog". This might be a stupid question/comment but if I pay for digital cable should it not be all digital?
Actually, that's part of the big deception with "digital cable". Not all the channels are actually digital. In fact, I believe of the channels from 2 - 70-something, very few are. Mainly just the local broadcast channels (03, 05, 07, 09, 010 and 013). If you go up to 103, 105, 107, etc., you'll find the local channels again, but these ones are actually in analog. Most of the basic cable channels (your USA's and Comedy Centrals - stuff that you can still get with analog-only service) are just being picked up in analog by the digital box. For the most part, the true digital stuff is in the 200+ range.
Anyway, my problem started a couple of weeks ago when I noticed that my cable box was reset and the vertical line started to appear. Does anyone else have this vertical line issue?
I've never seen an issue like that before, and it doesn't sound like any kind of signal or interference problem I've ever heard of, either digital or analog. Could be a problem with the box.
