    My 50 inch projection TV doesn't seem to want to take a the feed once
    the cable is connected to either ANT1 or ANT2. The picture comes up
    with grey fuzzy dots as if the cable weren't plugged in at all. I was
    working a week ago before we had a power outage, but after the power
    came back on i it didn't work. It plays the vcr no problem but i get
    no signal from the cable. Can anyone give me any feedback as for what
    to do or have any clues as to how to fix the problem. It would be
    greatly appreciated.

    Call a reputable repair shop to look into it. I would suspect that the tuner
    has been damaged. If not the tuner, then something in the RF or IF signal path.
    If you have no TV circuit diagnosis and repair experience, then you would be
    money ahead by calling the repair shop rather than attempting repair that you
    can't handle.
