CHANGING THE SCREEN ASPECT RATIO: ( From Manual )
The TV can display images in four different modes: Wide, Zoom, Panoramic, and Normal. Each mode displays the picture differently. To change the screen aspect ratio:
1. Press the MENU button on the remote.
2. Use the Arrow buttons to highlight the Wide icon. Press OK.
3. Use the Arrow buttons to highlight your desired screen mode and press OK:
• Normal preserves the content's original aspect ratio. Since the 4:3 aspect ratio is not large enough to fill the TV's screen, black bars are added to the left and right of the display image.
• Wide stretches a 4:3 aspect ratio picture to the edges of the screen. Since the picture is being stretched, the display image may appear distorted. If the program is already formatted for widescreen viewing (1.85:1 or 2.35:1), then black bars will appear on the top and bottom of the display image.
• Zoom expands images with black bars to fit the screen.
• Panoramic expands the display image to fill the screen.
images may appear wider than intended.
If you are watching widescreen (1.85:1 or 2.35:1) content, black bars will still appear on the top and bottom of the display image. This option is only available when the TV is displaying a 480i/480p source.

Hello

Watching standard cable on an HDTV can be quite a shock; the images are likely to be in a smaller aspect ratio, and have grainy or pixelated distortions. Additionally, the use of non-HD compatible devices, such as a DVD player, VCR, or older gaming system, will produce a less than stellar picture.

If you've changed the aspect ratio or your television, or have changed the zoom in or out, you may be encountering distortion that would otherwise not be noticeable. Setting the picture to a 1:1 ratio and turning off any overscan can help ensure a better quality image.

If you're using a system that supports HD, such as a Blu-ray player or an HD-compliant gaming system without the use of an HDMI cable, the image may be distorted. HDMI cables transmit both HD quality digital images and sound over one cable, and provide the best possible picture A/V signals.

The "picture size" on the TV needs to be set correctly. You should have a "ZOOM" button on your remote. Press it a few times, cycling through the options... see if this fixes the problem.

Be advised, many (most) HD channels do not show HD content all the time. At the broadcasters discretion, they may choose to ADD the black bars to either side (and/or top an bottom) of the image. This is what the "ZOOM" button is actually for... to allow you to correct this, filling the screen with the image.

*Note: many cable box have a "FORMAT" or "HD ZOOM" button. When used in conjunction with the TVs zoom feature, you can end up having one device set correctly, while the other is not. The result is often a picture that is expanded far beyond the bounds of the displayable area of the screen. If you can not find a solution using the "ZOOM" button, pick the setting which shows the most image. Now adjust the cable box setting (FORMAT / HD ZOOM).

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.

Press the RATIO button repeatedly to select the desired picture format. You can also adjust Aspect Ratio in the OPTION menu.

1. Set By Program. Selects the proper picture proportion to match the source’s image. (4:3 → 4:3, 16:9 → 16:9)
2. 4:3. Choose 4:3 when you want to view a picture with an original 4:3 aspect ratio, with gray bars appearing at both the left and right sides.
3. 16:9. Choose 16:9 when you want to adjust the picture horizontally, in a linear proportion to fill the entire screen.
4. Horizon. Choose Horizon when you want to adjust the picture in a non-linear proportion, that is, more enlarged at both sides, to create a panorama view.
5. Zoom 1. Choose Zoom 1 when you want to view the picture without any alteration. However, the top and bottom portions of the picture will be cropped.
6. Zoom 2. Choose Zoom 2 when you want the picture to be altered, both horizontally extended and vertically cropped. The picture taking a halfway trade off between alteration and screen coverage.
7. Cinema Zoom. Choose Cinema Zoom when you want to enlarge the picture in correct proportion. Note: When enlarging or reducing the picture, the image may become distorted. You can adjust the enlarge proportion of Cinema Zoom using D / E button. The adjustment range is 1~16.
   

The aspect ratio (zoom) button on the cable remote had been changed. On Brighthouse the # button toggles through the zoom settings. It's not a tv issue, it's a cable fix.

On the verizon FIOS tv box, turn the FIOS STB on, and turn on the tv, tap the following buttons on the Verizon FIOS STB )in this order) 1-Power, then Select, then Menu. This will bring up the FIOS STB HD options. Arrow down to 4:3 Bypass and set the bypass option to 480P. Hit power 2 times, once to turn off, second time to turn STB back on. This should on standard channels give you the zoom feature back. This worked on my Samsunf 5053 TV model.

You should contact Samsung service to know if the internal setup for the picture sizing was not adjusted properly at the factory.

Take care that some of these sets have a user zoom mode. Maybe it is in the zoom mode. Check in your instruction manual before calling for service support.

burn in is not supposed to occur on an lcd tv, however I have an lcd from Proview that leaves images on the polymer layer the white horizontal address bar is the most prominent. if I leave the monitor off for about 3 days the images disappear, this may or may not help you, if Samsung has created a ticket on this issue you may well receive a prepaid shipping label to return the tv for repair.
