[TV] Re: RCA model R52WH74 ITC222A Chassis special convergence problem
I had one of those recently that appeared to be a convergence problem, yet I
could get into the convergence menu and adjust the convergence red and green
crosses normally and the center of the picture was fine. All voltages on
convergence module were normal. Fix was resoldering connections on the
power/deflection board, I don't remember the locations but there were two
obvious cracked/burned connections on 2 capacitors. Fired it up, ran
autoconvergence, picture was perfect.
