Insufficient vertical height

I have a Panasonic TV Model No CT-32G13W. When the set is powered on, the picture fills the entire screen. At some point in time, retrace lines appear at the bottom of the screen and move vertically upwards resulting into a narrow picture. i know that it is a strong possibility that the problem is probably in the vertical output circuit. I tried to get a schematic from a vendor on the internet but the print is very poor and is impossible to read. I would very much appreciate if you would assist me in solving this problem.

    picture is significantly narrower than the screen. There is black space to the left and to the right of the picture. But the picture extends all the way to the top and all the way to the bottom of the screen. Is this vertical insufficiency? What causes it? What is the fix?

Horizontal lines across TV screen Pansonic CT 35g25

Check its vertical output section circuit for any component damage or loose soldering terminals. Check the solder terminals of the vertical output IC. Resolder all the suspected solder terminals by applying al little more fresh solder, without making any solder bridge short in between adjacent solder terminals.
If this do not help you, replace the vertical output IC. Lose of Vertical Scan is the problem of your TV.

It appears that the image on the screen is zoomed in, but I can't figure out how to "undo" that. Thank you!

If the image on screen is zoomed both in vertical and horizontal direction, your TVs power regulator inside it is faulty. [Overvoltage]. If it is zoomed in vertical direction only, that is only the height of the picture is zoomed, you can adjust it with the remote control button directly on going through menu and get in to the function menu. Normally all TV remote has a special button marked as "Zoom" which on pressing it once the picture get zoomed, again another press the picture gets wide and again an another press picture will come to normal mode. You should select normal mode to retify the problem.

Help with panasonic ct-z1410

If the picture is short top to bottom then the vertical is your problem . Check the caps in this area as they tend to become weak can't fill the verticals height . The transistor you talk about if it reads 1 ohm from the collector to the base or the emitter then the set would not work , But it will read 1ohm from the base to the emitter . Check the vertical . Good luck

Adjusting vertical height

I looked for info for your the Mct-2051 & imagine my surprise that Magnasonic not only doesn't have a manual for your model they don't recognize the model #. Excuse my sarcasm.

If MCT-2051 is not a typo, then the closest I could find was an MCT-2053 & there was no mention of a vertical height adjustment by software control. From my past experience this adjustment can only be performed by a TV tech because you need to access the inside of the TV.

The fact the picture has shrunk this much means that the vertical height driver is failing & eventually you will see nothing but a vertical line, stretched across the screen. Which will mean, that do to Magnasonics' lack of support, you'll be out of luck.

When shopping in the future for a TV try to stay with name brands who will support their products.

By the way, where did you hear that you could adjust the VH utilizing the remote? That could possibly be a function of digital device like a computer monitor, not an analog device like your TV.
