Hi All, Samsung 52" PTV model PCH521R Set has bad bow at both top & bottom, Convergence menu comes up but is way off and not adjustable. Found open (F855A) 3A fuse On +13v And -13v Supply Lines In Power Supply. I have no print on this Set. What would cause the 3A fuse to open? Are all (3) of the STK390-020 Convergence IC's bad?
