Sony #KP-61HS10 Convergence Problem

I have a sony kp61hs10 projection tv and need some advice. At first when i turn it on the convergence is bad but as it warms up it gets better and then it gets distorted. Before the convergence was terrible but I have replace Convergence ICs and Pico fuses in the past to fix problem and it made it better but not perfect. If anyone has any ideas or knows what the problem is i would greatly appreciate it!
