Toshiba 55H70

My set will not power on this happened after a power outage though may not be related. I checked the fuses F470,F850,F851,F860,F889,F890,F891 all are ok. The power switch on the front does nothing. I got a schematic and jumped the SR81 relay when I do that I hear the main power come up and I can tell the audio is powering up as I can hear it come on. I still have no red led on the front pannel though terminals 1 and 6 on PB11 have 4.8V supposed to have 5V. I think I don't have power to whatever powers the control part of the circut. Perhaps a transformer? I don't know how to tell? any ideas?
