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 to adjust vertical size my hitachi c29-r30sp


You could go into the user menu and look around to see if it has an adjustment. If not you will have to access the service menu for your tv. There may be a setting to adjust vertical size there. If that still isn't possible you may have to open the tv and look for a pot or a switch that can control the vertical adjustment. It may be by the vertical output circuitry. This could also mean that you have a defective component in the vertical circuit or inadequate voltage to that circuit.

Vertical Stretch


You need to adjust "vertical height" in the service program. You need to put the set in "service mode" to do this adjustment. If you google "enter service mode RCA F32665" you should find the procedure. It will be listed in abbreviated letters such as VERT SIZE or VERT HT. Follow the instructions for entering service mode and saving the data closely!! The data you change will be listed as a number between 1 and 63. The number will only need to reduced by a small amount and you can still see the picture behind the data and watch it shrink as you adjust the number down.Always burn the new number to memory (if required) before exiting service mode. Good luck
