Television blank , but there is a white line across tube. I can hear audio
Your TV is in what is called "vertical collapse". About 70-80% of the time it is due simply to bad solder joints on the vertical output IC. You can verify this by tapping on the side or top of the TV, the picture may jump back into position. If it comes back it's as simple as re-soldering the vertical IC. If not, the vertical output IC may be shot or it may be missing one of it's supply voltages.
If the picture has been shrinking or had lines at the top that means there are some capacitors in the vertical circuit that were drying out. If it happened all of a sudden I'd bank on it being just bad solder.
Don't run it like that with that bright line for too long or it will burn in on the picture tube. Then if you do get it fixed you will see that line there all the time!
