Question about Televison & Video
This is an old CRT tv. When the tube ages it's cutoff point (the value of the voltage on one of its cathodes at which the current that generates the image is completely cut off) gets lower so the return beam becomes visible. The image controller has some means to dynamically adjust that, but even this has its limits.
There is nothing left to fix in your tv - the tube has aged so much that the automatic adjustments can no longer compensate. The only way to fix that is to replace the tube but they are no longer produced for at least 10 years now.
This tv is dying of old age, time for a new one.

All plasma an Lcd ts have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them, but it is very easy to wreck em. Good luck.
I hope this will help in solving the problem.......
