Why comes white vertical line on my t.v?

Horizontal scan output fault. Check the connections to the deflection yoke from the main board. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience.

Tv out of foucs

These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

My TV suddenly has a big black rectangle in the lower center part of the screen, that dissapears only for a few seconds when pressing any button. How can I remove it?

Sounds like your Closed Caption has gotten turned on. Try this solution...

1) Press the MENU button
2) Use the CHANNEL UP/DOWN to scroll to CLOSED CAPTION
3) Use the VOLUME UP/DOWN to until MODE is OFF
4) Use the CHANNEL UP/DOWN to scroll to FINISH
5) Use the VOLUME UP to save and exit.

This should make the box go away.

Good Luck.....

What is subfield ? panasonic says subfiels what is subfield ?

Does this help
A standard video signal is actually a series of still images, flashed on screen so quickly that we believe we are watching a moving image. The typical frame rate used in North America is 60 frames per second (60Hz) meaning that a TV would display 60 individual still images every second. Sub-field drive is the method used to flash the individual image elements (dots) on a plasma panel. For each frame displayed on the TV the Sub-field drive flashes the dots 8 times or more, meaning that the dots are flashing 480 times per second (480Hz) or more. (Example: 60 frames per second x 8 sub-fields = 480 flashes per second). subfielddrive_en.jpg

TV changes colour to pink and then image dissapears

Sounds to me like a problem with tubes. In your TV there are "tubes." These tubes work better after heating up for at least 25-30 seconds, sometimes longer in older models. It might be a problem with them. Follow this link to read a small amount about tubes, and steering coils.

Depending on how old your TV is, you may or may not be able to find ones for sale. Google the **** out of your TV and you might be able to find the model # for you tube. Then google that model number tube and see if you can find one for sale.

The TV turns on and you can hear the sound but the picture is dark except for a thin line of blue dots in the center of the screen.

You have whats known in the biz as a cold solder connection on the vertical output IC or on the associated components. Not a job for the handi-man unless you know the issues with safty, and precautions to take with Hi voltage inside of tv sets. Shouldnrt cost much for the local shop to find your problem . Now on rare occations the poor connections are inside the IC and the IC has to be replaced. Good Luck
