Check the remote there would be a zoom button. Every time you press the button the screen of the Tv will change just like X2,X3,1/2X ect. select it to normal mode or OFF.

See if remote has a ratio or zoom button on it.

Try pressing the same button to rid of zoom. Or power off and re-start.

Ok, first make sure you or someone in family didn't hit the "HD Zoom" on your cable remote or whatever kind of remote you have. On ours - Cable- if you hit it once it is in "Normal" picture which on ours has black around edges on a non Hd channel. Then if you hit it again it Zooms once makes pix very large and if you hit button a third time brings it into a wide screen Zoom that fills the Tv screen. If we are viewing HD channels I put it on Normal which will fill the screen and give you the best HD pix. If we are viewing a NON HD channel, then normal will have black on sides, so I hit the Zoom a couple times to fill in the screen. My brother in law had this problem and couldn't figure out why his Sports channel Scores were always half cut off the screen! it was zoomed in too much for that channel. His sports channel was in HD so needed to be on normal instead of zoomed in.
if it is not the Cable remote then this is a second possible cause:

The other thing that happened to me was - we hardly ever use our original TV remote that came with the TV. but one day our picture looked weird and the cable remote didn't adjust it. One of us had hit the "P SIZE" button on the TV remote. this changes your pix from - 4:3 ratio to 16:9 ratio and vice versa. I put clicked that button and on the TV it shows whether it is at 4:3 or 16:9. For newer wide screen TVs you want that set at 16:9 ratio.

All cable company remotes probably are a bit different so check with your company ... to find out where the zoom control is on their remote.

Hello
You can set the picture size by remote control itself.

You can vide 480i format programmes in three picture sizes. 4:3, 16:9, and ZOOM
You can change the picture size by pressing the PICTURE SIZE button on the remote control.
4:3 Picutre size
To fill the screen, the top and bottom edges are extedted more widely, although the center of the picture remains near the former ratio.
If receiving a 4:3 programme, the image size is displayed in its originally formatted proportion.
16:9 picure size
This image displays the size of standard 16:9 with black bars at the top and bottom.
If receiving a 4:3 programme, the image is displayed with black bars at the top and bottom and stretched wider.

NOTE: If a fixed bar remains on the screen for a long period of time, the image can become parmanantly engrained in the screen and cause subtle but permanent ghost images. Never leave your TV for long periods of time while it is displaying these images.

Zoom picture size [for 16:9 formats]
The entire picture is uniformly enlarged --it is stretched the same amount both wider and taller (retains its original proportion). The right and left edges of the picture may be hidden.
OK.

I had the same problem after plugging my pc into the pc-in socket. The problem happened with the scart connections after.
I solved it by turning the tv off/on from the wall plug socket.

You will have a button on the _original_ remote that says Format, Aspect Ratio, Zoom, Size or just AR. It will cycle through Normal, Stretch, Partial Zoom, Zoom, Gray Bar, or the like. You are not in Normal but in one of the Zooms. Stretch is used to make 4x3 movies fill a 16x9 screen, may not be desirable. Zoom is used to fill the 16x9 screen with movies that have been letter boxed. Gray Bar fills the sides of a 4x3 picture on a 16x9 set with gray to "avoid" burn in. Use normal except zoom on LB. -Ken

i have the same problem. i finally went to "setup", "video" and selected "16:9". it doesn't fill the whole screen but it is better.

They may have gotten to the zoom function. There is a zoom button on the cncealed part of my remote. Hit the zoom button to cycle through all the screen sizes.
