Re: 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.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

To adjust the height of the picture, you have to enter its service mode option, and should adjust the vertical amplitude data value, accordingly. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. http://electronicshelponline.blogspot.com/
Check the aspect ratio set. If it is set to wide, there will be black bars at top and bottom of the screen. Go to its picture setting menu, and adjust the settings. If it do not help you, enter its service mode to adjust the picture height. Although this is a semi-skilled work, if you have patience and concentration, you can do this adjustment. There is no need to open the TV. If you wish to get more details about how to enter service mode, and adjust the data values there, check the site linked here. http://electronicshelponline.blogspot.com/
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.

4.14.1 Understanding Viewing Features
Your LCD HDTV features four viewing modes and Picture-In-Picture (PIP)/Picture-by-Picture (POP) mode.
You can switch viewing modes using the remote control. 4.14.2 Viewing Modes Normal Mode
The original 4:3 aspect ratio (1.33:1 source) is preserved, so black bars are
added to the left and right of the display image. Standard TV broadcasts are
displayed with a 4:3 Aspect Ratio. Movies in 4:3 Aspect Ratio may be referred
to as pan-and-scan or full frame. These movies were originally filmed in 16:9
(widescreen), and then modified to fit a traditional TV screen (4:3). Wide Mode
When watching a standard broadcast or full-frame movie in this mode,
the display image is stretched proportionately to fill the TV screen.
When watching a widescreen (1.78:1 source) program or movie, the
display image fills the TV screen. If you are watching a widescreen
(1.85:1 or 2.35:1 source) program or movie, there will still be black
bars at the top and bottom. Zoom Mode
When watching a widescreen (1.78:1, 1.85:1, or 2.35:1 source)
program or movie, the display image is zoomed proportionally to fill the
width of the screen. The top and bottom are cut off to remove most of
the source material’s black bars. This mode is good for programs or
movies with sub-titles. Panoramic Mode
When watching a standard broadcast or full frame movie in this mode,
the 4:3 Aspect Ratio (1.33:1 source) display image is stretched
horizontally on the left and right sides to fill the TV screen. The center
of the image is not stretched.
Note: Viewing modes are saved based on input. For example, you lasted watched a DVD in widescreen mode and then watched TV in standard mode. When you switch back to DVD input, the viewing mode will return to widescreen.
You don't give a model number or age of the set so I can't be too specific, but there is an adjustment for picture size (it's actually termed "vertical height") in TV sets. Many newer sets make adjustments through a service menu using the remote control, but many sets have a physical adjustment control inside. I can't tell you how it is in your set, but you can take the back off and look at the circuit board. If you see a small round adjustment control (screwdriver slot for turning) marked "vertical size," "height," "vh" or something similar, that's the one. A little turn one way or the other will do the trick.
Now having said all that, it's also possible there may be bad capacitors in the set's vertical circuit. Is this a problem that just started, or that's gotten worse over time? Do you notice distortion at the top of the picture, like a person's head or other round object looking stretched out if it's at the top of the screen? If so, that's usually a sign of capacitor failure. There are a few in the vertical circuit, usually in the range of 1 to 10 mfd at 50 volts, and they commonly go bad with age. Without knowing what model TV you have I can't suggest specific part numbers.
I think what your asking is for an on screen service menu?? That wont fix your problem. It sounds like you have a vertical height problem where the screen doesnt fill the entire screen with the Picture. The adjustments wont go out like that for no reason and all by them selfs. The vertical sweep IC went bad and is going to have to be replaced. This is not a job for the end user. You should call an experienced tech to assist you with this repair. Good Luck
