I was scanning the file I uploaded and it seems the SONY KP-61XBR38 uses two STK4278-L ICs on the D board. (listed on pg 184)
The SANYO part replacement cost appears to be around $17.95 each.
The Parts listing for the D Board lists:
F901 1-576-107-22 FUSE 3.15a/250V
F902 1-576-107-22 FUSE 3.15a/250V
The Parts listing for the D Board lists (pg 180):
