hi. this will be an easy fix for you if you are a good solder. you will need to replace the convergence chip that is located on the PC board(main). this chip is damaged and it has failed due to this damage that has occurred. click below for your new convergence chip(stk).

Convergence


Did you remove 1 leg of each resistor out of circuit when you checked the resistors? sounds like thier is still one resistor open or maybe one of the new IC pins need abit more solder.

Blue shadow


If the blue shadow is convergence you should have an option for convergence adjustment via the remote control to converge the blue onto the green. If it doesnt move then its probaly a IC problem. What make and model set do you have?
