OK new question. Being I got no replay on my first post. Can
some tell me if the convergence setup is the same for this modal
as it is for the PCJ522R? The schematic would still be great.
Thanks.

Found this tip in T/A
Garris TV, Make: Samsung, Model: PCH521R, Chassis
APT51B,
Problem: Convergence way off and unable to adjust, top/bottom bowed-in.,
Cure: Open 3A on P/S Module located on right side of chassis, this fuse
protects the -26v going to all (3) STK391-020 Convergence IC's which are
located on left side of chassis on large heat-sink. Replaced 3A fuse on SMPS
board and replaced all (3) STK391-020 Convergence IC's on the Convergence/Sound
board.
Comments
3A fuse is good. Before I change all three STK?s, looks like a
pain in the axx?s. Anyone have any quick fixes? No leakage from
tubes.
