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.

My Zenith C32V28 television does not display the top and bottom of the picture. I phoned Zenith tech support who told me that it was the satellite signal. I called the satellite provider who advised me it...


This is applicable to Bell Television Services (Canada)
I solved the problem myself after two calls to both Zenith and Bell Television satellite service. On the bottom left of the Bell remote control there is a * (STAR BUTTON). Press this * button and within two seconds you must press the channel change button up or down. This will do two things. One; it changes the channel; and also changes the ratio of the satellite signal. There are three satellite signal ratio settings. Try this when you are tuned to a TV channel such as BNN (Canada) (Business News) or The American channel which has a stock ticker usually displayed along the bottom of the TV screen. Select the ratio (setting) that allows the stock ticker to be displayed......hope this helps.........Jim McP

Zenith Z25X31D Verticle Adjustment


open up the set and on the board there are 2 small potentiometers mounted on the board called Vert-Linerity and Vert Height, I believe the adjustment of the Linerity control will fix your issue

Zenith Z25X22S 25" TV can't read scores at top or bottom


On the inside of the TV, there will be a knob with a RED cap on it, labeled vertial position. (it actually looks like a variable inductor)

With an allen wrench (possible 1/4) give it a half turn in either direction and see what happens. On the Z25x22S model, the vertical and horizontal position adjustments should be right next to eachother, but on the model i worked on, there was no variable pot for the horizontal position.

Hope this helps!

Picture too tall. How do you shorten?


Picture displaced vertically, picture too high or low
This problem was cured by entering the service mode (menu then 4,7,2,5), then pressing the green fastext button to access geometry settings, selecting VP1 (vertical position) and adjusting as necessary
Very low width and bowed verticals,no ew correction. R626 o/c
C630 (390nF, 300v) faulty, located next to scan socket. This fault can also be caused by R629 (2R7 fusable) o/c. In my set C630 was dry-jointed but not faulty. Check generally for dry joints in the E/W and PSU areas. Note that R629 is a safety component

Picture Shortens, Converges, eventually the set shuts off - $50 for Correct Solution


Open the TV amd turn it on in a position you can see the picture, possibly through a mirror. Now gently tap all of the metal heat sinks on the circuit board until you find the one that is sensitive it will have a small chip mounted vertically on it, with probably like 7-10 pins. The number on the chip will most likely be an "LA****" number. Now turn the circuit board (UNPLUG FIRST) over and resolder the pins. This is your problem 99% of the time. Be very careful there is High Voltage inside this TV.

Sansui - BOTTOM OF SCREEN CUT OFF


Your problem is not a vertical alighnment or size adjustment. No, Im sorry to say its the old vertical output IC and /or the small capacitors around the ic and in the vertical circuit. If you dont have the right tools, like a soldering iron a multimeter know how to read a schematic diagram, then you should seek out a repair person to assist you in this repair.
