Its pretty easy check your remocon for the button that writes
ratio press it continiouly until you find the 16:9 ratio
hope you get it right

Sounds like you have the "Wide" mode set to Zoom or wide zoom. Also if you are on Comcast cable the cable box has a setting of Zoom and full. Set your TV's zoom setting to "Full" and the cable box to Full. I don't have an LG so you'll have to find these settings yourself..

You do not worry at all, because the set is under warranty.

Launch a complaint and sit peas fully.

On the remote control there is a zoom button. Your picture is zoomed in x2. You need to set it to normal.

try to disable the zoom or set it normal size

I just had this problem and got it solved. The issue is that your cable box is likely set to the wrong aspect ratio, so your tv will not be able to display the picture properly without this setting changed. On my cable box(Pace), you need to turn the power off to the cable box using the remote. Then hit the menu button on the remote and a new menu will appear on the screen. Change the aspect ratio to 16:9 and you should be all set. Hope this works for you too.

Turn off zoom option in picture format/ screen settings menu.

I have Time Warner Cable and just FIXED this problem. On the cable box remote, there is a button with the word "Aspect" on it. On my particular remote, this is the "#" button (pound symbol) and by pressing that button, it gives you options of "Zoom 1", "Zoom 2", "Stretch" and "Normal". By setting it to "Normal", it completely solved the problem. Oh and by the way, my t.v. is the LG 47" flat screen LCD. Hope this helps the other frustrated folks out there.

I had the same problem with my westinghouse 47 inch HDTV. It turned out that someone had inadvertently hit the "format" key on my satellite (Direct TV) TV remote controller. If you have satellite TV you might want to check this out. I set it back to the previous setting and I get the entire screen. Hope this helps someone.

Normallly, if the picture size button on the remote for the television does not achieve the desired affect, then, a cable box or a satelite box is where the change needs to be made.
For example:
Some Motorola Cable receivers need to be set up in the menu to go to a wide screen or zoom mode when an analog signal is detected. There may be a format button on the remote.
Some Dish Network boxes have Size buttons on their remotes and also in their main menu.
It's difficult to determine the repair without knowing the types of the peripherals.
Hope this helps.
