Sharp aquos lcd tv screen gets fuzzy

My sharp aquos lcd tv has a problem with the picture quality. the screen will get fuzzy for a few seconds and then it will be fine for a minute or two and then get fuzzy again. i can still see the picture but it has squiggly lines on it. it only does this with a coaxial cable hook up, when watching a dvd with the video inputs it is fine. i believe it has a problem with the coaxial input. is this something i can replace or do i have to take it to a repairman?

You need to change your TV's settings and enhancements. Directly from the store and out of the box, the settings are adjusted for easiest sell in the store. That means that:
Your contrast is cranked to 100. Move this down to 50 to 60.
Your brightness may also be cranked up high. Lower it to a level nearer the middle range but not so dark as to lose detail in the shadows.
Your TV is set on "Dynamic" or "Vivid" mode. Pick "natural" or "normal" or standard.
Your sharpness is at least on, if not cranked up. Turn sharpness down or off, and the same with "Edge Enhancement" and "VSM", all to off.

Lastly, I bet you upgraded size and you are now sitting too close to the TV. Roughly, if you are sitting closer than 130 inches (about 11 foot) you might do some rearranging or save some money and get a smaller TV.

SOURCE: turn off closed caption on input(component) on Sharp Aquos 42"

ok had to post this one with reference to the above problems
My area St Augustine Fl. .. COMCAST (THOSE PAIN IN THE A--) SERVICE INSTALLED A NEW BOX IN MY HOME THE OTHER DAY ... I KEEP SEEING the box go thru dowmloads

then the very next day I started to see the colosed caption across my screen
SOLUTION ... with tv on and box on ( be in cable mode) press MENU on cable remote ,press power button, press menu again, look at screen and where it says caption make sure it is disabled
Mine was enabled ... change it and problem fixed ... I spoke to comcast finally after trying all day and they confirmed that with their new down loads to box it triggered the CAPTION to be ON

anyway problem was fixed ...

I read all prevoius posts and tried them all ... so may be this will work for problem that someone is having as of 10-9-2008 ( I could not believe that they could do that but they sure can COMCAST is just a PAIN in the A--

thanks to all who post solutions and I had to do my share and maybe be able to help someone else.

How do i change from 480i to 1080i on a sharp 52"


You don't. The TV picture will be fuzzy when watching a program in 480. If you have a lot of video in 480 or 720 you can get an up scaler. They are expensive, but that is the only way you'll ever get a Hi def picture from a low resolution signal

Change your input source. You are probably on Input Source "TV". My HDMI cable is plugged in INPUT 4 so make sure that your TV is set to the right INPUT.
