I recently connected my TV to basic cable (it is also connected to my DirectTV and DVD receiver via component through a Maratz reciever) and was unable to get a picture. I noticed that cable TV comes through in PIP but while on the normal screen all I see is a black screen. I would like basic cable to watch the football playoffs. Aside from this the DirectTv and all else works well. I would greatly appreciate any input on why this is happening and how to correct it.
