Subject: [TechAssist] Sony KPR-46EXR15 Convergence Problems


This Sony KPR-46EXR15, Chassis SCC-F19E-A came in with a severe bending
of the raster in the lower left quadrant. I found F902 on the convergence
 board blown. I replaced IC905, STK4278L and the fuse.
I turned the set on and both fuses blew. Should I have replaced both
STK's? Any other componets
that could be faulty?

TIA,
