Can anyone tell me what is wrong?
Thanks a lot.

Probably bad capacitor(s) in the vertical circuit - though this is less
common on Sony than some other brands.

The specific symptom you state may be caused by a "boost" capacitor being
bad. If so, the vertical output IC is running really HOT and will fail.

Also, there is a chance of burning the tube at the top where the lines are.
This is permanent damage.

so DON'T USE THE SET in this condition . Get it fixed. Or replace it, your
choice.
