Yes there is but there are 3 capacitors in the vertical circuit that go bad causing a height problem,white lines on top,or a very small height. change the capacitors in the vertical section.the yoke on the back of the picture tube has 2 coil sets on it,one is horizontal,and the other is vertical.the connector next to the flyback transformer is the horizontal. follow the wiring from the other connector and it will take you to the vertical drive ic located on a heat sink.the three capacitors go bad because of heat from the heatsink cooling the vertical drive ic.

The vertical sweep output section of your tV has the fault. Replace all the electrolytic capacitors [5 or 6 of them there] at one time. Height to the picture is more than normal is the fault now.

Top of screen disappeared...cant see score of game


The Height adjustment is off... look in the back of the TV set, it has some knobs in the back, one should be vert.lin for Vertical Linearity adjustment, and there is another call Vert.Hgt. for Vertical Height adjustment. try adjusting the Vertical Height first with someone watching in the front of the big TV to see if the top comes back into view, you might have to adjust the knob very slowly one way then the other way, to make this adjustment. If it doesnot adjust take it to a TV shop to get it repaired.
Good Luck.

CF3273A Toshiba Vertical height and linearity problem, looking for adjustments


I'm not real sure what year this set is. Most sets 5 years or newer have service menu adjustments. Unless someone went in and adjusted it to get it out of adjustment, adjusting is not going to do much good. I would be looking for bad capacitors in the vertical circuit or possibly the vertical output IC. These IC's tend to run pretty hot anyway so they are usually the problem along with leaky caps.

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.

If the height has dropped down, you need to first find out why. Most likely there is a bad capacitor in the sweep power supply or the vertical output section. Good Luck
