The picture on the T.V is bowed toward the center, with the top and right side bowing the most. The bottom and left side are not so noticiable, and there is double picture(the 3 colors aren't lined up right)

With the bow in it it's likely the convergence has failed... Where did you purchase the amps that you put in it? Did you use a good heat sink grease to mount them?? Did you really scrutinize the resistors in the feed and return circuits???
Do you mean that at the top of the picture, the red color has shifted downward, bowed towards the center? If that is what you see, one color suddenly bows toward the center on any side of the picture, then it means that one of your convergence IC's has burned out and needs to be replaced. It is a good idea to go ahead and replace both STK392-110 IC's with the newer improved STK392-150's. If you have never replaced convergence IC's and realigned the convergence circuits in a projection TV then allow a qualified tech to handle it for you.
you have a convergence problem.. If you understand how this works then you can go into the set find the convergence ic's and replace them and sometimes you need to do some alighnment as well. Its always best though to let a service tech do a job like this as he will have all the proper equipment to adjust and troubleshoot the set Good luck
