Screen suddenly has only a thin bright middle

If it has a white line in the middle running left to right the problem is in the vertical circuit.

This can come with age as solder connections (this is the most common cause) come loose or break at the chip in that circuit.

Much of the time with set on a good hard rap on the top or side and the line will try to open and return a full picture.

Someone who can get to it and can solder can fix that---the chip will usually have 7-13 pins and be mounted on a metal plate that is fairly small(it keeps the part cool)---fixed a lot in less than ten minutes.

You will have to open the set, locate the chip(usually a location number on top of board by it will be something like IC301 or 401).

Most of the chips will have a generic number on them a LA------ or such. You will have to remove the board to look at the bottom where the chip solders in.

I attach a photo of a typical chip.

If you have a white line on screen---middle that runs left to right it is a vertical circuit problem.

This can be a easy repair: The set uses a chip---usually 7-13 pins in a straight line package-----a lot of these sets the solder from heat breaks loose and all that is needed is to resolder the pins on that chip.

A hint: usually a good solid rap on the top or side will in this case try to make the picture open up.

You need to be able to get to the part and solder.

TV: bright line across black screen for several hours.

vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch

Horizontal line on screen

The most common problem would be a bad solder joint on the vertical drive IC. It could also be a bad solder joint on the flyback transformer, as it supplies voltage to the vert. stages. If you disassemble the set, please be careful not to get shocked. Discharge the high voltage stages as a precaution.
