To adjust the data value to these adjustments, you have to enter the service mode option to your set. There is no external preset resistors [as in the old model TVs] for the new version TVs.

The text along the sides of the tv screen are not completely in view


you need to change the 'zoom' on the tv by the remote.
Normal mode frames the 4:3 video to the 16:9 picture area by displaying it in its original aspect ratio, with vertical gray or black bars on both sides of the screen. The disadvantage of this method is the fact that the image is small by virtue of not using the entire width of the screen. This is also known as the 4:3 mode.
Full mode Full mode horizontally stretches the 4:3 video evenly across the entire width of the screen. This is the proper mode to display anamorphic video. If used for standard aspect ratio video, everything on the screen will appear wider than normal. Contrast this with anamorphic video displayed without processing on a 4:3 display, in which people on the screen will appear taller than normal. This is also known as the 16:9 mode.
Zoom mode Zoom mode evenly stretches the picture both horizontally and vertically, until the picture fills the entire width of the screen. This crops out the top and bottom of the picture. This mode is used for letterboxed and open matte video.
14:9 mode Main article: 14:9
In 14:9 mode, the picture is magnified more than in Normal mode, but less than in Zoom mode, while retaining the original aspect ratio.
Wide Zoom mode Wide Zoom mode, also called Just mode, Horizon, or Smart Stretch, progressively stretches the picture horizontally, less in the middle and more on the edges. This allows normal aspect ratio video to be displayed across the entire width of the screen, with minimal cropping, and with much less of the unpleasing visual stretching effect of Full mode.

One horizontal line center on the screen


The vertical deflection circuit has failed, or has been shut down by a service code entered from the remote control*. Usually you can get out of service mode by turning the set off and on again.

*Normally, you have to enter a special combination of front panel and remote control codes to get into service mode, then enter another code on the remote control to get the horizontal line. The horizontal line is used for adjusting the screen controls for each color so you get proper color in the dark areas of the picture.

Red horizontal curvy lines


You need to turn the voltage on the red tube down slightly, also you would need to adjust focus to compensate for the lower voltage to the red tube. On the left and right bottom side of speaker cover are two round covers, take them out and there are 2 1/4" hex screws take them out carefully take cover off, there is another service cover same hex screws remove. You will see the focus block on the right side, tubes are labled on block. 2 knobs for each tube. Make voltage adjustments while tv is on a black screen, then for focus, turn color all the way off in the menu, and adjust focus until it looks right in black and white. These adjustments should only be very small; if alot of adjustment is needed, you may have other issues.

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.
