    Hello. I purchased both convergence IC's but have a question as far as high voltage. What is the best way to deal with the flyback transformer, where the high voltage is coming out? Do i take all three wires from that dsitribution transformer? Any other pitfalls around the high voltage? Will the high voltage dissapate after some time?

    Red and blue lines aren't lined up, so it causes shadows

You should not have to worry about high voltage as long as everything is unplugged. If you are worried leave it unplugged for a few minutes... the service manual warns to discharge the picture tube anode to the CRT conductive coating and wear goggles, but any charge should discharge after just 10-15 sec at the longest.
