If your TV has a menu button, go into the menu and try setting the input of the TV to the jack that you connected your cable to. Sometimes the TV will not check all the inputs and just does the default one when you do the auto-tune search function to find the active channels. Also, check to see that your wall receptacle is actually hooked into your active cable TV line. You should have a splitter somewhere in the same line that your other TV is using. If not, that jack that you are hooking up your new TV to is probably not active.
SOURCE: turn off closed caption on input(component) on Sharp Aquos 42"
I have a Sharp Aquos 46" and go a Comcast HD receiver as well, and had the same problem turning off the Closed Captioning. I order to turn it off you need to go into the box user setting by (starting w/ the cable box and tv on) pressing the power button for the cable box then the menu button for the cable box. This will open up the user settings menu. Just toggle CLOSED CAPTION to DISABLED.

what cable company do you have because you should have a cable box because only a cable box can scramble the frequency so you can get the channel you subscribe for
SOURCE: no sound on analog channels
Grab your sharp remote and press MENU, arrow over to SETUP, arrow down to RESET and press enter and follow that prompt to reset the unit. Once that is complete turn the tv off and unplug ONLY the tv for one minute then plug it back in. Then turn the tv on and see if you have channels, if you do, your audio should work on you analog stations, if you have no channels and all you see is a snowy picture do the following press MENU, arrow over to SETUP...arrow down to CH SETUP and press ENTER...you will then be at a screen that says AIR/CABLE, press ENTER, select CABLE or CABLE(STD) if that option is available to you. after then, arrow down to CH SEARCH, press ENTER, then you should be highlighted on ANALOG AND DIGITAL SEARCH...press ENTER and wait for 15-30 minutes ( or until you get a picture back) and make sure you DO NOT press any buttons or turn the tv off and you should be good. good luck 2 u
