Hello. I have an RCA model R52WH74 with an ITC222A chassis with what I have gathered (from reading other threads here) a convergence problem. There is a black dip in the top of the screen and nowhere else. My auto convergence option is no longer in the menu. After reading here I decided to open it up and see what I could see. I do not see any burns or bad connections (not a pro though) I did find where to manually move the colors. Turned on tv and started "moving the colors"....I can move all three colors (individually) horizontally and vertically , but that dip at the top is keeping things from lining up properly. Is this in line with an IC, resistor, or fuse problem? Do I just need to order one of these "STK" parts and go from there? Any help would be greatly appreciated.
