On this particular model there is one capacitor from the video process IC (jungle IC) that supplies the Vertical pulse that shoul be changed.
This is an easy repair if you've ever soldered and would not be too costly for a repair shop to do it for you. The problem is a bad Vertical Output IC (usually mounted on an aluminum heat sink with the part on it labeled LA78?? ) and 1 or 2 bad capacitors. Some times you can even fix the problem by re-soldering the contacts of the IC- To find the IC follow the 4 wires that come from the Yoke (which is a contained coil of wires slipped over the neck of the picture tube(s)) back to the board. 2 of the wires go to the horizontal o/p and 2 to the Vertical o/p the thinner gauge wires are for the vertical. Be sure to vote/rate me if this helped Thanks!

Toshiba TV (about 7 years old)

You had parts in the vertical deflection circuit failing, most common are the vertical output IC and possibly several capacitors also in the same circuit.

It is my guess that you have some intermitent solder connections in the Vertical output circuit.

Vertical size of picture

You have a number of bad capacitors in the vertical circuit. If you can solder, you should be able to repair this yourself. I'll look up your model to get the parts needed.

Yes...this TV may be repaired. The line you describe is in the center and is horizontal across the TV. You will need to resolder the vertical IC pins. This vertical IC is mounted on a large heatsink. Under the board you will see there are 5 or 7 pins that will have rings around them. Resolder these. And you should replace two or three capacitors that are next to this IC. A bad cap will overheat an IC and separate the solder grounds. If you can find my expertise page on this website, you will see the repair in more detail. Thanks for asking and show a few hands of support.
