This still sound like you may have a problem with the vertical, try turning up the 'Screen' control on the flyback and see if you get a thin horizontal line across the center of the screen; if you do there is still a problem in the vertical section.
It will likely be an open low value resistor (1 - 2 ohm) that is used as a fuse for the vertical IC. The resistor could be located near the flyback (it will be some place between the flyback and the vertical IC).
Another possibility is a bad capacitor near the vertical IC that is causing the vertical IC to short so the new IC may have shorted instantly when the set was powered on.
Do you have any other numbers on the set (ex: Chassis number or service number) I can't seem to find the model number in my notes or I may have been able to find the exact components to change.
