How do you adjust vertical size on westinghouse tv?

If model indicated here is correct either a problem in the Vertical circuit of the set or an adjustment.

Almost any shop can take the set into the service menu and adjust vertical size a bit to correct if not circuit problem.

Vertical and horizontal adjust went out with black and white TV pretty much.I remember those days too...what would kids nowadays do???lol.Anyhow,the fact that it clears up sometimes when you slap it should mean that the screen is fine.Something on the circuit board may need repair.Unfortunately,I have searched for diagrams for TV's online many times and only authorized shops have the access required.I just checked westinghouse,not even a way to sign in if I were a reapir shop.So,needless to say, a shop will have to check it out.Sorry That's all I can suggest and good luck!

the lines are from the vertical control, theres a minor short on the vertical board if not fixed the power supply will short and whole tv will go green call repair shop and get short fixed

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.

on the back side of set should have a control that says vertical size/ sweep. it is recessed into a small hole or has protruded knob, if so used a small flat tip common screwdriver for the adjustment. make sure you can see the control knob or slot clearly otherwise you could short out something!!!!!

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

There is a black box appearing on about 75% of the screen. How can I remove it???

There should be a vertical height adjustment control potentiometer near the vertical output IC on the right side of the PC board near the front section of the TV that can be adjusted to shrink the picture vertically. Be careful not to short anything out or getting yourself shocked in the process if you decide to try to adjust it yourself. Good luck. This chassis has also been known to have bad solder connections in that area also, so don't man-handle the printed circuit board roughly.

your pic. has shiffted vertically. very easy to fix. open the tv set, located the crt tube(end of the screen) there are four wires going down to the board that is compined in one socet. around that socet, you will find small knobs, look for vertical phase and you could adjust that pic. the adjusting should be done while the tv is on and has pic so be careful, you are dealing with a live electricity. good luck

you have to get into the tv to do the adjustment. take the cover off and then look for the CRT tube and follow the yoke cables that will lead you to the printed circuit. you should see some small tiny knobs there. something like vertical phase or horizantl Phase..you need the verital to adjust the vertical size of the pic..good luck
