Toshiba TV

[TonyGol]

I have a Toshiba TV model# CE35F15 which is 10 years old. The unit worked great until this weekend when all that was left was a 1/2" white horizontal line in the center of the screen. The audio works fine. Anyone know what part went bad? And where to purchase?
Thanks,
Tony

You said white line in center, of this is down the middle then it's a line scan, usually scan correction components or dry joints a possibility...

... if its across the middle then it's the frame/vertical scan problem, this could also be dry joints or a faulty vertical output drive chip.

Leaving it on with a bright line will burn the inside screen coating and cause permanent damage, better to keep this at a low brightness to avoid tube damage.
