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.

What is cost of yoke for panasonic ct tv?


You're discussing about the width problem to picture. If yoke have a short in between its wingdings [even a single winding short], will cause the failure of horizontal output transistor. As per you report here, the set has a raster, but problem is with the picture width.
There possibliliites for this fault are.
1. Lack of voltage from the SMPS power supply output.
2. Horizontal width capacitor.
3. Horizontal output capacitor.
Check the output voltage from the SMPS section first, and confirm that it is OK.

My tv screen shrunk in from the sides


Ok, you have a problem in the Horizontal output circuit--width etc.

Going to be a shop repair as most shops will not tackle this in the home--36 inch from the model indicated so expect repair to exceed 150 parts and labor.

If the border is not large on both sides the set also has a tech menu accessed with the remote--adjustments are there for centering and width--it will not fix a circuit problem.

The picture keeps on changing size.Can I fix this easily?


Hello, I need some more details so I can help, whether the image has grown in height or width? Or that the picture has grown at once, even height and width together? In addition I need the TV model, it says on the sticker at the back of the TV.

Blank screen but it has sound, when i turn on there is a horizontal line in the center of the screen, before it goes blank but still have sound, i already check all the resistor on both power supply and...


Your fly back, horizontal is in good condition but the possible fault is in the deflection coils or the deflection correction , pin correction section or the hirizontal width coils.
Please check them one by one as they are found along the sides of the flyback sections. check the continuity of the horizontal coils, it can also be a leak/burnt coils that can cause this problem.

Picture image does not look full when showing people


There is a service menu adjustment. I have seen several of these sets with bad components in the horizontal width control circuit. maybe your other set has a width problem. put both on the same channel. like cnn with the ticker on the bottom. what is the difference in size?
the width adj. procedure is: with the set off. use the remote, enter. MENU>5>VOL+>POWER . the set will come on in the service mode. then with the menu adj. buttons you can step threw the service menu to H.WIDTH adj. until full picture. also VERT. HEIGHT. when you are done adjusting make sure you press the mute button and watch the word WRITE flash from green to red or you won't save your adjustments.

Hello, I think you have a faulty "horizontal width" or horizontal
linearity preset pot. This pot will be located on the main PCB
and you can adjust it with a small screw driver, when you do the
picture will shift from left to right or vice versa, or move back to fill each side. If it wont hold after making the adjustments then the pots ( potentiometers) need replacing, which means unsoldering them from the printed circuit board( PCB) and take them in to your local radio shop for new ones. By the way you might need 2 pots ( 1 for the WIDTH and 1 for the LINEARITY)
Good luck.
