Re: Need access to service menu to adjust vertical size

No service menu for this set. Sounds like you have a bad yoke winding on this one....accordianman

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.

Zenith tv picture is larger than screen

There are Horizontal and Vertical size controls behind the back cover that need to be adjusted using a hand held tool. This adjustment requires a trained tech. High Voltage from the set is dangerous.
However, there maybe some limited controls that may help through the on screen menu.
To get into the setup menu, you need the original Remote that came with the TV.
Hold the Menu Key down until a box appears in the corner of the screen, then press 9,8,7,6 Enter. this takes you to the service menu. Just scroll through the items to find Horiz Size and Vert Size.
Good luck

Cannot make horizontal and vertical size and position adjustments

OK...I paid a whole $50 for an Apex AT2702 that had [undisclosed] vertical zoom, horizontal shift, vertical shift and width issues. Before I raised hell for the person who sold it to me, I decided to first exhaust all alternative solutions.

I found that in order to tweak these settings, you have to be in service mode and must have a service manual which I can email upon request.


1-Reduce your tv volume to 0
2-press the MUTE button on your original tv remote [you'll see "Mute" in red on the screen]
3-AT THE SAME TIME, press MUTE on the same remote and MENU on the tv controls.
This set your tv into service mode [there will be a red "S" at the top-center of your screen.

You'll need the table in the service manual page 47 where there are V-SHIFT, H-SHIFT, V-ZOOM, E/W WIDE default values that will need to be changed. WATCH YOUR SCREEN as you change the values to ensure you don't over do it.

If you have news ticker and sports scores issues, you'll want to be tuned to CNN, FOX, ESPN or whatever to see how your changes are applied.
If you have tv guide problems then tune to that channel or press info and see what happens when you make the changes.


This has worked for my set and you may attempt this solution on yours at your own risk.
I'm no longer pissed off that I got a bogus tv because it now works just fine and I can see everything!

Good Luck!
