Pan TH-50PX80U Dead no Schematic

[Ltank]

The TV is dead no voltages at all on the outputs. There is AC across F002 but no power across any other fuses. I don't hear the relays click. Relays are 5vdc. I can't find a schematic for the
NOAE6JL00001 MPF7719 Power Supply. Obviously with no 5vdc the 5 volt relays will not turn on AC power to the rest of the supply. What's the best way to trouble shoot the Nec F9232 microprocessor? IC 601. Manuel says IC 701 No schematic

There's a couple of 7W 10 ohm ceramic surge-limiter resistors on the PSU that fail.....

No 5vdc. All fuses are good. The 5vdc relays don't click. Relays were tested with external P.S. on bench out of the TV.
