Plug J102 back in.
Power on.
Measure AC voltage between J102 pins 1 and 4.
It should be about 18VAC.
Report back.

Quoted from at1105:

Between pins 1 & 4 measures 17 VAC

That's good. That is what it should be.
Remove and "buzz" F111 to ensure that fuse is good.
After that, next step is to test BR4.

Oh. Forgot it was a RD.
Follow the trace from F111 to a pair of large diodes. Those two diodes will also connect to two other diodes. Test all four of those diodes.
