Cold solder joint on the power supply or in the vert curcuit. If you know anything about the proceder to troubleshoot cold solder connections GO for it but if you dont and dont wanna cause any other problems with the set My advice would be to take it to a pro before any other problems arise if they already havent. Its not a major repair most of the time.

Tvs use high power so becareful if you take it apart. There is usualy a large red wire that goes into the top of the tube this is the one that can hurt you. Ive seen them discharged before and they make a loud crack when they discharge indicating serious voltage.

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!

Line across the tv no sound no picture

If you look carefully at teh line it should be red, green, and blue close together to appear like a white line. If this is the case, then the vertical circuit has failed. This is often poor solder connections at the vertical IC or a defective IC. Expect a parts cost in the $20 range for this repair.

Picture up side down

change the verticle cables on the deflection coil on the tube.
note just the verticle cables ( verticle has only two cables)
what is happening is that current is reversed.

Sound but no picture

A white like across the screen means that the vertical circuit has stopped working. Look for a small fuse that looks like a resistor near the vertical output IC, replace that fuse if open and resolder the pins on the vertical output IC.
