TV works fine for a while, then the picture disappears.

I would just replace the TV, the parts are not going to be made to repair this. The set is just to old.

the vertical drive ic that drives the yoke for vertical sweep has blown.
sometimes it is solder problems like sharp and toshiba had.
the part is 10$ the pc board will label it ,the yoke is the coil setup on the picture tube.if you follow the wiring half goes to the horizontal drive,and the others to the vertical section.the chip drives the coil directly.there are VERY high voltages in there ,even turned off. the pix tube cap on top is 30000v. like a stun gun.the horizontal drive 2000 volts and the main power supply 165 volts dc high need a special setup to discharge the picture tube.

Horizontal Line through middle of TV screen

This is usually a bad elect capasitor or a bad solder connection on the vertical IC, The capasitors will be close to the vert chip..Sometimes you can clear problem with a light tap on the TV, if so then suspect bad solder.

Curved horizontal lines in picture

Its Sounds like Convergence Circuit,If you take the Back off and look on the right side you should see a Board with Big black Ics Mounted beside a Large Heatsink,Mark the wires where they go and Make sure the POWER is Off Pull the Board out and Inspect the Connections from the ICS,you find Circle Breaks,They need to Be resoldered and That should fix the Set....
