Recently moved into a new condo. Had Comcast install my cable and
internet. I told the cable guy that the TV pictures seem kinda fuzzy.
He recommended that I purchase a signal booster. I have used these
before so I was very familiar. Purchased one from Radio Shack for
around $50 that plugs into electric outlet and also has a gain control
knob. Installed it and it improved fuzziness immediately. However, now
on some stations top of TV picture very bright. Seems to be worst on
Bravo. Top of picture bright while bottom seems fine. It affects all
TV's in the house. I have adjusted the gain switch. Makes no
difference. When I disconnect the signal booster, problem goes away
but picture gets fuzzy again. Any idea's? Maybe Radio Shack Signal
booster is defective?
