Samsung PCH521R May need schematic. Convergence problem.
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.
