The picture is oversized and the printing as in the stock ticker or in the sports scores can only be seen a little bit on the bottom. Can't find anyway to resize the picture.

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 do I change it from wide screen to regular? I have a black area above and below the picture.

You can set the picture size by remote control itself.

You can vide 480i format programmes in three picture sizes. 4:3, 16:9, and ZOOM
You can change the picture size by pressing the PICTURE SIZE button on the remote control.
4:3 Picutre size
To fill the screen, the top and bottom edges are extedted more widely, although the center of the picture remains near the former ratio.
If receiving a 4:3 programme, the image size is displayed in its originally formatted proportion.
16:9 picure size
This image displays the size of standard 16:9 with black bars at the top and bottom.
If receiving a 4:3 programme, the image is displayed with black bars at the top and bottom and stretched wider.

NOTE: If a fixed bar remains on the screen for a long period of time, the image can become parmanantly engrained in the screen and cause subtle but permanent ghost images. Never leave your TV for long periods of time while it is displaying these images.

Zoom picture size [for 16:9 formats]
The entire picture is uniformly enlarged --it is stretched the same amount both wider and taller (retains its original proportion). The right and left edges of the picture may be hidden.

This RCA set uses the CTC187BD chassis. Look on the back of the set and to the right of the cable connector you will see 2 controls sticking out, one on top of the other. The top control is for focus and the bottom one is screen, or overall brightness. If these controls have been turned clockwise then you will have a bright, fuzzy picture with white lines (retrace lines) through it. Tune in a channel with white letters on the screen and turn the top (focus) control until the letters are crisp and sharp. Go into the menu and turn the contrast and brightness all the way down, and then turn the bottom control (screen) until you can just see the picture, just above the point where the picture is too dark to see. Go back into the menu and reset the contrast and brightness and the picture will be back to perfect.
