Sharp Aquos LCD 32 inch

Just wondering, recently redid a few things with the TV that I have and now, after changing cable providers, the TV when on the TV channel says 'Falure to recieve signal' or something along those lines but still works fine when used with my PC or PS3. Any clue whats going on or do I need to update the firmware again?

  1. Can you tell that it is a tv message and not a cable nox message.?
    The tv is on channel 3 and channels switched with the cable box?

    Its not a cable box, its just regular cable from the coax line from the wall to the TV
  3. Go into tv setup and scan channels using the various options.(analog, digital, air, cable, whatever is there.) still no signal?
    Most cable systems now require you to have a decoder box. that way they can charge you 5-10 more per month.
