Re: Black screen with white horizontal line in middle of...
The solder connections at the vertical output integrated circuit are bad and losing contact as the part heats up. A few minutes with a soldering iron to repair the connections should fix that up.

You would need to replace the flyback on this and your looking aroung $65 parts and $85 labor to shore this problem up. We can recommend you a repair shop or you can purchase a new TV its all up to you
Did you mean the picture is collapsed only in the middle horizontally(white line appears on the middle part of the screen)? If that is the case, maybe vertical IC failed or loose connection.
You don't have to buy a new tv, it is a fairly simple problem, your vertical ic is blown, and it could be the powersupply to the vertical ic also. To verify, slightly increase the screen voltage, and a horizontal line will appear on the screen, if the voltages is okay, change the ic, but first try resoldering the ic pins. Good luck
caution
whenever you see horizontal line please reduce brightness of your tv for safety of crt.
your problem in vertical section only mostly due to loose contact in
connector,print or loose components.
