I have the same problem. i know it involves changing the Aspect. there is an Aspect button on the remote which does not work for me, but could for you? also, after pressing the menu button, some options come onto the screen and i used to be able to get to Aspect that way also, and now i can't. i hope you can! if not, do we need a manual for it? good luck.

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.
Press the RATIO button repeatedly to select the desired picture format. You can also adjust Aspect Ratio in the OPTION menu.
Set By Program. Selects the proper picture proportion to match the source’s image. (4:3 → 4:3, 16:9 → 16:9)
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.
16:9. Choose 16:9 when you want to adjust the picture horizontally, in a linear proportion to fill the entire screen.
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.
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.
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.
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.
Is the onscreen menu just as distorted and are the lines across it or behind it? The pop you heard may have been a capacitor and since the TV is still powering on, it's the probably the video controller board that is on it's way out. If the onscreen menu looks fine, you maybe having a problem with the input board only so try a DVD that uses a different input and if it's poor, I would say the TV needs to have the input/output board service. If the OSD is distorted as well then it's definitely the video controller board and service is likely required.
