Sounds like you may have caps going bad . Adjusting may tend to only stretch the the picture too much . Also when you say horizontal are you saying the top and bottom are closing in ? If yes then your problem is in the vertical section . If side to side then check the horizontal section . Good luck

Which service manual setting controls horizontal size?


You're discussing about the factory mode adjustments. The horizontal width adjustments will not be there. You have to adjust it by replacing certain capacitors at the horizontal output stage.

Horizontal lines, they can go away for awhile if we move the TV, but they come back. Most annoying. Can't figure out if there is such a thing as a "horizontal hold" button on this thing, but I...


Hello

If your TV has nice thread like horizontal lines on the entire screen, at aboug 1 inch apart or so, it is due to the high screen voltage. In some sets, this voltage may go high due to a defect in screen control adjust preset, integrated to line output transformer [LOT].
You just open your tv and locate the screen adjust control. It can be seen on the above said LOT itself. There will be two adjustable controls, one for adjusting focus voltage, and the other for adjusting the screen voltage.
Dont touch the focus adjuster. The screen adjuster will be at the bottom of the focus control, and both of them have visual markings there stating 'Focus' and 'Screen'.
Just turn the screen adjust control a little, while looking the picture on the screen, and adjust it till the lines on your screen just disappears. Never turn more than this position. The turning must be counterclokwise, not clokwise, as this should shut of your TV.
Take every precautions when we works with an elelctrical equipment. As high as 25,000VDC points are there, while tv is working, you should be very cautious. Do this with confidence. Take care. OK.

Scrolling screen


There's a horizontal adjustment that needs to be made in the TV. If you feel mechanically inclined, you can take the back cover of the TV off (Be very careful with this. If this is a CRT (picture tube) then there is a capacitor at the top that has ALOT of stored energy.) You will see a couple of potentiometers (Looks like a little black wheel with a slot for a screwdriver). One of these will be the horizontal adjustment. Very slowly try to turn this until it adjusts.

If you give me the model number and brand of the TV I can try to find you a manual that will help you determine which one to adjust.

Green tint I can't seem to fix


Hopefully someone on here has a manual and can tell you exactly where the tint controls are. Also need to try adjusting the color level, turn it clear down so you have a black and white picture.
Is the picture still green over the screen with the color control
set clear down to black and white? If it does, you might
have an issue with the green gun going out or problem in the
circuitry to it.


By the way, the best way to adjust the picture settings on a
tv are to first turn the color control clear down, then adjust
brightness and contrast for best black and white picture, then
bring up the color level to where it should be and adjust the
tint for best red/green ratio.

The bottom third of the screen is black and the rest of the picture is scrunched up. it is a part failure so not possible to adjust it. as it has developed watching tv so it is a part failure in vertical section. in vertical section there is a feed back ckt.it is due to electrolytic capacitor (most probably)or any other component but in feed back ckt. it is a common failure it is not major problem.can be rectified at your place with in no time by a skilled tech.

Color Problem after replaced Circut Board


When you replace the entire board in a Zenith TV, you must make the adjustments to align the new chassis with the old picture tube. You must adjust the CRT bias and drives as well as the horizontal and vertical parameters. On the older boards there were controls on the main and CRT boards but on the newer boards the adjustments are made with the remote control after entering the service mode. Tune in the shopping channel QVC, set the color and contrast to minimum and lower the brightness until the picture is just visible. Set the CRT bias settings for a pure black and white image, then increase the brightness and contrast to get a very bright picture and if necessary adjust the drive settings so that the bright picture is pure black and white. Return the video settings to normal and then adjust the vertical and horizontal settings so that the info boxes on QVC are centered top, left and bottom. If you are not sure that you can do that right then have a qualified tech handle it for you.

Picture is too large for the screen, horizontally.


No my friend, there is a problem with the width circuit, and this would be in the pincussion correction circuit of the TV set. There is alot of high voltage in this circuit, and if you have no TV repair experience, play it safe and call in a tech to service this for you. there is not any adjust ment that will fix this. Good Luck
