When TVs first appeared, they had an picture ratio of 4:3, which matched that of most movie screens at the time. Terrified of losing their business, movie studios struck back with "widescreen" films using 1.85:1 or 2.35:1 ratios. When widescreen TVs started appearing, they emulated those same ratios, but many TV shows (and some movies) were still in 4:3---and we were eventually left with a bit of a mess. Canny manufacturers, including LG, have solved the problem by allowing you to adjust the picture ratio on the TV to fit the program you're watching. If it's not set properly, however, your image will look distorted or cut off. A quick bit of troubleshooting can fix the problem easily.
Press the "Menu" button on the remote and scroll down to the "Option" title (it should be second from the bottom ). Then select "Aspect Ratio." You should see a list of ratio options. You simply need to pick the one which fits the show you're watching.
Choose the 4:3 ratio for older movies and TV programs. You should see a pair of bars on the left and right side of the screen. (That's okay: the bars keep the program in the same proportion in which it was filmed.)
Select the 16:9 ratio for widescreen movies and for more recent shows to match their longer width. For some movies, you may see black bars and the top and bottom of the screen. Again, that allows the movie to be shown in the manner it was filmed.
Pick "Set By Program" to automatically switch the LG TV between 4:3 and 16:9 to match whatever show is on at the time.
Select "Horizon" to horizontally expand the image onscreen. It will fill the whole screen---eliminating the black bars to the left and the right---but it may look distorted.
Use the "Zoom 1" option to zoom the image forward. That will eliminate the black bars at the top or the bottom of the screen, though you will cut off the edges of the image.
Pick the "Zoom 2" button to select a midway point between "Horizon" and "Zoom 1." The picture is stretched, but not as much as with "Horizon," and fills the screen, but doesn't cut off as much as "Zoom 1."
Use the "Cinema Zoom" button to enlarge the picture to fit the screen. This option allows you to adjust the proportion to your liking, rather than use the set proportions of the other aspect options.
Exit the menu when you are done and watch your programming normally.
A lot depends on what the TV station cuts off also. If they are transmitting a 5 X 4 picture, your TV will try an reproduce it giving cut off edges or top and bottom. It won,t fit properly. Hope that helps to explain it.
ok, There are 2 aspect ratio's for tv/movies.
If you have a Widescreen TV, Widescreen formatted dvd's will fill the hole screen, Standard formatted dvd's will not fill the whole screen
if you have a Standard TV, Standard formatted dvd's will fill the whole screen, Widescreen formatted dvd's will not fill the whole screen
this is normal, check to see the format of the dvd you are trying to use.
If you are watching widescreen format movie or tv programming on a non-widescreen tv, that is how it will appear. The widescreen is a wider picture so to show it on a less wide screen, it has to shrink down to fit. and leave blank space top and botton.
There are settings on most DVD players as well as TV's that allow you to adjust the type of display you want. Make sure both the DVD and TV are set to the same display type (usually either 16:9 for your type of TV). If that still does not fill the screen you will have to use the Zoom function on either your DVD or TV. This will cut off part of your movie, but should allow you to fill the screen. Most DVD movies will also allow you to choose widescreen or normal viewing from their menu. Again, you will lose a small part of either side of the movie, but at least you will fill your screen.

4.14.1 Understanding Viewing Features
Your LCD HDTV features four viewing modes and Picture-In-Picture (PIP)/Picture-by-Picture (POP) mode.
You can switch viewing modes using the remote control. 4.14.2 Viewing Modes Normal Mode
The original 4:3 aspect ratio (1.33:1 source) is preserved, so black bars are
added to the left and right of the display image. Standard TV broadcasts are
displayed with a 4:3 Aspect Ratio. Movies in 4:3 Aspect Ratio may be referred
to as pan-and-scan or full frame. These movies were originally filmed in 16:9
(widescreen), and then modified to fit a traditional TV screen (4:3). Wide Mode
When watching a standard broadcast or full-frame movie in this mode,
the display image is stretched proportionately to fill the TV screen.
When watching a widescreen (1.78:1 source) program or movie, the
display image fills the TV screen. If you are watching a widescreen
(1.85:1 or 2.35:1 source) program or movie, there will still be black
bars at the top and bottom. Zoom Mode
When watching a widescreen (1.78:1, 1.85:1, or 2.35:1 source)
program or movie, the display image is zoomed proportionally to fill the
width of the screen. The top and bottom are cut off to remove most of
the source material’s black bars. This mode is good for programs or
movies with sub-titles. Panoramic Mode
When watching a standard broadcast or full frame movie in this mode,
the 4:3 Aspect Ratio (1.33:1 source) display image is stretched
horizontally on the left and right sides to fill the TV screen. The center
of the image is not stretched.
Note: Viewing modes are saved based on input. For example, you lasted watched a DVD in widescreen mode and then watched TV in standard mode. When you switch back to DVD input, the viewing mode will return to widescreen.
Check the aspect ratio of your widescreen DVD. I'll assume that your flat panel TV is widescreen, which would mean it has a ratio of 16:9. Some movies are even wider than that (i.e. 2.35:1), so it would be normal for you to see black bars at the top and bottom. Look for a WS DVD described as 16:9 (usually shown on bottom on back). This should fill your TV screen and not distort the image. If you still see the black bars, you will need to check your DVD menu settings for widescreen aspect, and supply more info on the DVD player and TV.
take your set to a tech you are having problem in your vertical output circuit.leaky filter or coupling capacitor,or defective B+ regulator transistor or IC .buffer transistor or IC,or supply resistor, they need to be replace.good luck
