Model tc1393. how do i adjust vertical size - Emerson TC1351 13" TV

To do this adjustment, you should enter the service mode option. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

Service mode entry, adjust and exit procedure to many popular brand TVs are given.

Usually this means that a cap in the vertical circuit is starting to fail. Are there any other symptoms at all? Does the height seem stretched more at the top?

if your vertical section of your mother board has a vertical adjustment trimmer, adjust it to reach your desired vertical size..if doesn\'t have, increase the resistance of the resisitor only connecting from cold ground to the negative of the e.cap and the positive pin of e.cap connecting to the line 1 of the vertical focusing coil. the common value of the resistor you would focuse is 1ohm, try add with .5 or 1 ohm depending with vertical size result.

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.

If you are using a DTV coverter box, you may have changed the aspect ratio with your remote control. look for a button marked "aspect" or "picture size" use that to change size.
If you have a cable box, you may have a similar button.
Or you may find a picture size adjustment on your TV remote.
If you do not have "aspect" button on your remote try going to set up menu and look for picture size.
Older TVs used to have a vertical size adjustment at the back. look in the manual.
If none of the above, you have a biiger problem with the TV internal parts needing attention

try to adjust the vertical cont....

Generally vertical issues on a set are from a bad panel

most likley they are in the tech menue
you would need the service manul to access the proper proceedure the cause may be caps going bad in the vertical circuit

well its all new now could be bad caps or vertical i.c. okay if you have a esr meter check around the i.c. for a leakey cap good luck

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.

Hope this helps or gives you a start.
