Re: Adjust manual picture on TV
Sounds like you may have caps going bad . Adjusting may tend to only stretch the the picture too much . Also when you say horizontal are you saying the top and bottom are closing in ? If yes then your problem is in the vertical section . If side to side then check the horizontal section . Good luck

hi sir have you been already tried all the picture format at picture settings. automatic, super zoom and wide screen. try also in picture settings go to vertical shift adjustment and horizontal adjustment to adjust the position of the picture.
Hi, There is button "Wide Mode" on tv remote, press it repeatedly to select desired zoom mode to view best fit picture in screen. Click Sony Support link to download user manual free copy and check page-48 for details. Thanks.
There's a horizontal adjustment that needs to be made in the TV. If you feel mechanically inclined, you can take the back cover of the TV off (Be very careful with this. If this is a CRT (picture tube) then there is a capacitor at the top that has ALOT of stored energy.) You will see a couple of potentiometers (Looks like a little black wheel with a slot for a screwdriver). One of these will be the horizontal adjustment. Very slowly try to turn this until it adjusts.
If you give me the model number and brand of the TV I can try to find you a manual that will help you determine which one to adjust.

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.
Verical position is hard to adjust and is in service menu. A service manual will get you there, but you might get lucky with the vertical size adjustment. If you open the front of the TV, the vertical size is adjusted with a knob on the deflection board. Remove the speaker grille and take off the access panel. You will see two knobs, one horizontal and one vertical. Be careful, those red wires have 30,000 volts on then, don't touch anything but those knobs. If its just an adjustment, the v-size knob will fix. Set it so ESPN ticker is just above the bottom of the screen. *Service mode - the manual tells little but entering is done by "press and hold the input button, press the power button, release both after you hear HV come up" .. the v-pos parameter is in there, but this manual doesn't say where or how to adjust, procede at your own risk. If you get into trouble, pull the power so you don't save any settings. I believe you just navigate through the menus to find the parameter and use arrows to adjust. Enter may save. Sorry the service manual I have tells nothing much.
Hopefully someone on here has a manual and can tell you exactly where the tint controls are. Also need to try adjusting the color level, turn it clear down so you have a black and white picture.
Is the picture still green over the screen with the color control
set clear down to black and white? If it does, you might
have an issue with the green gun going out or problem in the
circuitry to it.
By the way, the best way to adjust the picture settings on a
tv are to first turn the color control clear down, then adjust
brightness and contrast for best black and white picture, then
bring up the color level to where it should be and adjust the
tint for best red/green ratio.
