1981 Magnavox with a problem.

[Firebird]

I am a little confused. Last week i resoldered the half of the chassis that has the flyback and it came on. Displayed a black and white picture with no sound. This week i resoldered all the modules on the sound and color half of the chassis and the flyback starts arcing. Still no color except for red and no sound. Why the arcing when i did not work on the flyback. I did solder the connection pins on the color and sound side of the main board. I double checked my work, no cross solder. Could the flyback or tripler be getting too much voltage?
