I have a TV with the properties written below:TVC TOSHIBA 3373 DG CODE 697635 .Today when I turned on my TV, I had the sound but instead of showing the image, there is just a bright horizontal line in the middle, and all the rest of monitor is black.I wanted to know what's the problem of my TV and if is it economic to repair it.thank you for responding my question.

You've lost your vertical deflection. Probably a shorted output transistor, or maybe an open-circuit output transformer. Could instead be any of dozens of other component faults, though less likely.

Should be a reasonably straightforward repair for a TV technician. Being a big (expensive?) set, it's probably worth having repaired.
