This the PFC in the 5VSB. It is IC1 in the schematic.
BG1 looks like it is wired wrong and would cause the fuse to blow upon application of line voltage. I take it that you derived the schematic from the PCB? I can sort of make out some numbers on IC1 in the photo, but not well enough to be sure of a part number. The photo is very good, but maybe with the lighting from a different angle, we could make out the part number on IC1.

Already have it. Quick question.... Years and years and years ago when I was repairing TV'S I was replacing 5GH8's and 6BK4's. Then we had a monthly Sam's subscription. I notice now on Sam's web site they list a photofact for this model. Do you know if it includes the schematics?

No sorry I don't know if it does.Looking through this service manual it is not that great huh? not that much info in it, almost nothing as far as schematics go...
