If the main IC is not putting out a vertical drive signal then the vertical output will not do anything and therefore will not be damaged. What exactly do you mean by the set "literally eats deflection IC's"? What is the number on the vertical output IC? I will bet that your pump-up cap or pump-up diode is defective.

A vertical line means the line is up and down in the middle of the screen. That would indicate that the vertical IC and the surrounding components are working perfectly. A vertical line as described is the result of a lack of horizontal deflection (to move the beam from side to side) Since the high voltage is obviously OK, the problem is most likely a bad solder connection in the horizontal yoke circuit. Examine the bottom of the PC board in the area of the flyback transformer, and yoke connector (has four wires Red, Blue, Green, Yellow).and the pincousion coils, capacitors, etc in between. Flexing the board in that area may cause the problem to come and go. Resulting arcing should also be visible. BE CAREFUL, as hazardous voltages are present in the circuit!
