These units have a reputation of loose solder joints in the horizontal/high voltage circuit. As this is a dangerous circuit be carefull if trying to repair it yourself. Always unplug before attempting a repair. Start by soldering the horizontal driver transformer. This is a small four pin transformer just off of the base of the horizontal output transistor. Solder these four pins and work your way soldering everything up to the horizontal output. While you are there be looking all over the board for little burnt places at solder joints. Next, work your way from the collector of the horizontal output to the high voltage transformer. Remember also to solder both legs of all components that you come across. Solder all the legs of the high voltage transformer. I hope this helps and thanks for using fixya. I am here to help.

There are defective components in the vertical circuit. If you can solder and are comfortable working inside the set (there are dangerous high voltages present even when unplugged), you can fix this. Let me know and I'll provide additional details and instructions.

The H.O.T tranistor and flyback transformer are bad. This can be fixed cheap if you find the right shop. Transformer cost about $22. and the H.O.T transistor is about $6.00. The labor is what you have to shop for.
