Normallly, if the picture size button on the remote for the television ( If it has a picture size or format button) does not achieve the desired affect, then, a cable box or a satelite box is where the change needs to be made. For example: A Motorola Cable box needs to be set up to go to a wide screen or zoom when an analog signal is detected. Some Dish Network boxes have Size buttons on their remotes and also in their main menu. It's difficult to determine the repair without knowing the types of the peripherals. Hope this helps.

To do this adjustment, you should enter the service mode option. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. http://electronicshelponline.blogspot.com/ Service mode entry, adjust and exit procedure to many popular brand TVs are given.
Factory setting will not cure a convergence problem---in customer menu look for convergence and see if it will adjust---if not and looks 3d etc parts have to be replaced and set adjusted.
There are kits for this available on the internet by brand and model number.
May or may not be a do it yourself repair depending on what skills you have.
Zenith sets, like most others now, are adjusted electronically through a service menu. You'll need your original remote control (or a Zenith-brand universal replacement with a MENU key) to access the menu. Press and hold the MENU button until the channel number and time display goes away, then press 9, 8 , 7, 6, ENTER. This puts you into service mode.
In service mode, CHANNEL UP and CHANNEL DOWN move through the different settings, and VOLUME UP and VOLUME DOWN change the values. Make sure you write down the original value of anything before you change it so you can put it back if necessary. One of the reasons the manufacturers hide the service menu is because the set can be damaged by incorrect settings to some of the parameters.
On some models, you can't get to all the parameters unless you change
one called F MODE from 00 to 01. You might need to do this on yours.
The list of parameters varies by model and features. I haven't worked on a Zenith in a long time so I don't remember exactly what yours says, but you want to find two settings for V SIZE (vertical size) and V POS (vertical position). Adjust the size first by lowering the value until the top and bottom of the screen are black. Then adjust the position so the picture is centered (black strips close to equal size). Finally, increase the size until the picture fills the screen again. It's normal to adjust for a little overscan, meaning you push the top and bottom a little bit out of view. If you stop too soon, on some channels you might see flashing lines at the top of the picture.
When you're finished adjusting, turn the TV off to exit service mode. If you needed to change the F MODE setting, put it back to 00 first. Your picture should be properly sized after all this.
How much to big? have you tried pressing the "Aspect" button on the remote to change the picture size? Futher adjust ments can be made by pressing the "Picture Pos./Size" button.
This information can be found on pages 22-24 of the Owners Manual. If you do not have you user manual here is a link to it:
If you are using a DTV coverter box, you may have changed the aspect ratio with your remote control. look for a button marked "aspect" or "picture size" use that to change size.
If you have a cable box, you may have a similar button.
Or you may find a picture size adjustment on your TV remote.
If you do not have "aspect" button on your remote try going to set up menu and look for picture size.
Older TVs used to have a vertical size adjustment at the back. look in the manual.
If none of the above, you have a biiger problem with the TV internal parts needing attention
Chances are, if it's an older set, componants have changed value through use over time, which also includes the picture tubes and associated driver circuits. The way to compensate for this color drift is through adjustments. Either turn the red down a little, or turn the blue and/or green UP. Be carefull though as there are potentially dangerous voltages in and around the circuit boards and picture tubes.
( If it has a picture size or format button) does not achieve the desired affect, then, a cable box or a satelite box is where the change
needs to be made.
