Model # KP-53XBR200, had bad convergence, replaced 2-STK 392-020, & one 3.150 amp picofuse, now auto focus works ok, & overall convergence is fine...just off a bit, but I get a code of E17G right after auto focus is finished. I can't see how to get into the basic customer convergence menu. It isn't in the customer menu. Is there a special way to do convergence? Thanks, Dani.
